The nervous system (NS) denotes a collection of human body organs as well as connections, which have expressly differentiated cells referred as neurons or other specialized biochemicals, tissues, and supportive cells that assist in the normal working of the human body NS (Swanson, 2015). The human nervous system helps in addressing acquisition, processing, understanding, storing, as well as coordinating or transmitting signals in the body. Therefore, many body organs, as well as sensory organs, possess discrete and different roles. The nervous system (NS) can be categorized into two, that is, peripheral nervous system (PNS) as well as central nervous ...

Part A: Cranial Nerves:

There are 12 pairs of cranial nerves emerging from the brain’s underside passing via cranial openings leading to various parts of the head, neck and body trunk. These nerves are naming, and numbering of these nerves is based on their position i.e. from the anterior to the posterior of the brain. In this case, the olfactory nerve is CN1 while CN12 is the hypoglossal nerve (Wissmann, 2013). In this paper, only four of the twelve cranial nerves shall be discussed i.e. the Olfactory nerve (CN1), Oculomotor Nerve (CN-III) which are sensory nerves, and the Trigeminal Nerve (CN-V) and ...

Mechanics function of the spine

The human body is meticulously designed with a complex and specialized skeletal system that helps not only provide support and structure for the body but enhances motion and stability. The spinal cord is the extension of the brain and it forms an essential part of the central nervous system. As people age the mechanics of the body are altered (NiosiOxland 2004). Degenerative processes are inevitable and as such, the facet joints, discs and vertebrae are affected. These degenerative issues of the spine include the degenerative disc disease, which is well known; others include Slipped discs, Spinal stenosis Osteoarthritis and ...

Question 1.
Insect-eating birds will decrease in number since their source of food has been reduced. The birds may also migrate to warmer areas during this period.

Question 2.

The habitat is the specific place where the organism lives e.g. a fish’s habitat is water. On the other hand, niche is the position and the role played by the organism in an ecosystem. It includes how the organism obtain food and shelter, the mode of survival, and the mode of reproduction (Sutton & Anderson, 2009, p. 46). For instance, a lion’s niche in the ecosystem is that of a predator.Question ...

Vestibular Projections

Vestibular projections in the central nervous system consist of vestibular end organs which communicate with the brain stem and the cerebellum via the vestibular branch of the eighth cranial nerve. These nerves are also connected to the auditory fibers. Thus damage caused to these structures can cause both vestibular and auditory disturbances. The vital function of the vestibular system is to coordinate head and eye movements. The ability of the eye to stay focused on an object even while the head is moving is brought about by the vestibular system.

Vestibular Cochlear Nerve

The vestibulo cochlear nerve or the auditory nerve is ...

Surgical Anesthesia

Pharmacology and Indications
Licocaine
Licocaine is a type of medication used with an aim of numbing tissues and nerves within a given area of the body, which provides that anesthetic effect for the body. The most popular brand names for this particular drug are xylocaine and lignocaine. Some of the common effects associated with this particular medication include drowsiness, muscle twitching, nausea, and confusion (1). The severity of the side effects depends wholly on a patient’s reaction to the chemical composition of the drug. Regarding its mode of action, licocaine works by blocking the voltage-gated Na+ channels, which ...

A. An anticholinergic is a drug used in the treatment of diseases such as asthma, muscular spasms, insomnia and gastrointestinal cramps (Healthline, 2016). The drug is also used with anesthetics as it inhibits the action of parasympathetic nerve impulses by preventing acetylcholine reaching the receptor cells of nerve impulses. This may lead to memory loss, confusion, drowsiness and even sedation. These effects are more pronounced in old-aged people. Loss of muscular strength and fainting is a symptom which could be seen in the patient. Use of anticholinergic drugs is not recommended for patients with conditions like glaucoma, hyperthyroidism, heart ...

Introduction

Diabetes refers to a metabolic disorder of several etiology. The disorder is typified by chronic hyperglycemia and metabolic disturbances of fat, carbohydrate and protein due to insulin deficiency, defect in its action or a combination of both (Alberti & Zimmet, 2004). The chronic hyperglycemia leads to damage, dysfunction of several organs including the eyes, heart, blood vessels, kidneys and nerves (American Diabetes Association, 2011). Diabetic patients present primarily with excessive thirst, loss of weight, blurring of vision and weight loss. Long standing diabetes is associated with complications such as retinopathy, cardiovascular diseases, neuropathy, hypertension and metabolic abnormalities. There are two types of ...

Introduction

Nervous system is categories into two major systems The Central Nervous System and The Peripheral Nervous System. The Central system nervous consists of the brain and therefore the neural structure (Sanes, Reh, & Harris, 2006). The cerebral mantle, that is concerned in an exceedingly type of higher psychological feature, emotional, sensory, and motor functions is a lot of developed in humans than the other animal. It’s what we tend to see once we image an individual's brain, the grey matter with a large number of folds covering the neural structure. The brain is split into two symmetrical hemispheres: left (related to ...

Question 1

The cerebellum is an essential part of the neuromuscular system in that it plays major roles in the timing of muscular activities and the smooth progression of one muscular movement to the next. The summary of how this is done is that it sequences all the muscular activities necessary for a particular movement, and then makes corrective adjustments as necessary when the movement is being executed so that they conform to the motor impulses being generated by the cerebral cortex and other significant parts of the central nervous system (Ganong, 2005).
For instance, for an individual holding a cup and ...

A. The human cerebral cortex is divided into three main areas: sensory, motor and associated areas (Association Cortex, 2016). Sensory areas belong to the peripheral nervous system. They extend from the spinal cord to the receptor cells located in all parts of the body. The primary function of sensory area to carry impulses from the receptor cells to the brain for interpretation. These impulses can be those of sensations like touch, pain, smell, taste and sight. The motor area or the primary motor cortex is located in the interior part of the brain at the central sulcus. Its pyramidal ...

Human perception of sounds is not only performed by an ear as a part of the body. In fact, a person hears through the organ of hearing, which has got complex structure. The ear is only a visible part of it.
Auricle or pinna essentially acts as a funnel through which a person catches vibrations in the air. Coming through the auditory canal, they affect the eardrum – a thin membrane that separates the outer and middle ears.
Then the eardrum vibrations are transmitted to the auditory ossicles and reach the inner ear, the main part of which is an organ called the bony ...

Lou Gehrig's (ALS) disease is a health disorder that is also known as amyotrophic lateral sclerosis, abbreviated as ALS. The symptoms of the disease include muscles becoming smaller and weaker, and at the same time lose sustenance. Pain in the spinal cord because the disease affects parts of the spinal cord, and it is in the spinal that the nerves that nourish muscles are located. Development of hardened or scarred tissue in place of healthy nerves is also a symptom. In health care provision, there are ethical issues and principles that determine, and control actions that health care providers take in ...

Spina bifida is a birth defect involving the incomplete development of the spinal cord or its coverings. Normally, it occurs towards the end of the first pregnancy a time when both sides of the embryo’s spine do not succeed to join together thereby resulting in an open area. There are also cases when the other membranes or the spinal cord may push through this opening in the back. This condition however is detectable before the baby is born and it can be treated right away. It is the most common of a group of defects known as neural tube defects which ...

Specifity is the change that occurs in the body as a result of training. Specificity in athletics comes in when the athlete trains repeatedly performing specific activities in preparation for the exact requirements of a sport. Distant runners require doing exercises that would make them adapt to sustained running. On the other hand, throwers need to train in a way to build up their muscles in size and thickness in order to ...

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system. It is characterized by a triad of inflammation, demyelination, and gliosis; the course can be relapsing and remitting or can be progressive. Some nerves found in our body are encased by myelin. These nerves have faster conduction speeds then would be found in unmyelinated nerves. Segmental demyelination of the nerve as caused by multiple sclerosis has been shown to be due to an autoimmune reaction, with auto-reactive T lymphocytes, B-cell activation, and the release of cytokines (Harrison’s, 2008, pg.-2612). The axonal damage leads to a progressive and irreversible ...

1. Motor pathways: Briefly describe important differences between the lateral and the medial (motor) systems

ANSWER:

The motor system is the corticospinal tract. The lateral part of the corticospinal tract decussates while the medial part does not. The lateral corticospinal tract controls limb muscles while the medial corticospinal tract controls the axial and trunk muscles. The lateral corticospinal tract carries contralateral fibers from the cerebral cortex to supply the limb muscles while the medial corticospinal tract carries ipsilateral fibers from the cerebral cortex to supply the axial and trunk muscles.

The Corpus Callosum is the largest commissure, which facilitates communication between the right and left hemispheres of the brain. The views on the value of the Corpus Callosum are varied: from the most "useless" to those defining the higher cognitive functions of human brain structure. According to modern concept, the role of Corpus Callosum is not limited to the transfer of information. This commissure enables meta-control of the information in both hemispheres, as one of them must establish the function of its processing (Banich, 1995). Corpus Callosum not only transmits sensory information, ensuring its double representation in every hemisphere, ...

The term ‘Ergonomic' denotes two phrases of Greek, ‘ergon' that implies work, as well as ‘nomos' that implies laws. Currently, the phrase describes the art of devising a job or activity to fit a labourer and not compelling a labourer to fit a task (Salvendy 274). Ideally, this implies designing a workplace to offer the feasible attainable comfort as well as avoiding work-related injury or stress. Ergonomics encompasses all facets of a task that ranges from some physical stresses work places on nerves, bones, joints, muscles, as well as tendons to environmental issues that impairs vision, hearing, or overall ...

Rene Descartes is a French philosopher and mathematician of the XVI century, considered as a father of modern philosophy. He defined an opening point of existence and he is an author of well-known dictum “Cogito ergo sum” that means “I think; therefore I am.” He was influenced by Plato, Aristotle, Anselm and Thomas Aquinas.
Descartes’s famous proofs of God’s existence are based on the system of personal experience and the “I” conception but in his speculations, it was not a person that have a conversation with God but the idea of the human “I” as a thinking ...

Three nursing interventions for a post-operative patient

The three nursing interventions that can be offered to a post-operative patient include the diagnosis for acute pain, diagnosis for nausea and diagnosis for risk levels for infection (Heater, Becker, & Olson, 2008). Acute pain that is related to reflex muscle and surgical incision are diagnosed by complaints of restlessness, pain, irritability and facial grimacing. This type of pain can be corrected by assessing the location of the patient’s pain and giving him or her appropriate analgesic and teaching and then assessing their correct usage of the same. Other than drugs, other methods such as massage, distraction and imagery ...

Cranial Nerve Palsy

Cranial Nerve Palsy is when the nerve is lacking its functionality. This condition may cause a partial paralysis or weakness of the areas, which the affected nerves serve. In some cases it may cause complete paralysis and weakness on such affected nerves (aapos.org).
This nerve condition can be traumatic, congenital, or can be vascular disease and infections. Symptoms of Cranial Nerve Palsy affects the eye movements and diplopia. The orientation of diplopia is going to be different based on the affected cranial nerve. Besides limited movements of the eyes, this condition also causes droopy eyelid or ptosis and sometimes ...

The Central Nervous System is the control system of the human body; it is the core of the human nervous system. The Central Nervous system is made up of the spinal cord and the brain. The brain uses the electrical signal, which is generated by the Central Nervous System. These electrical signals travel via the Peripheral Nervous System effector cells. These effector cells carry out physiological responses whenever the brain demands it. Axonal regeneration occurs successfully in the Peripheral Nervous System. However, regenerative axonal growth starts occurring in the Central Nervous System too, but stops two weeks after the ...

The Intervertebral Disc Disease

The intervertebral disc disease is a condition that involves herniation, deterioration and intervertebral disc dysfunction. The condition is common among the aging group. As a person is aging, the nucleus pulposus gradually dehydrate, and this limits its ability to transfer and uniformly distribute the loads inter-vertabrally. Instead, the loads are transferred non-uniformly via the annulus fibrosus as it undergoes a progressive structural degeneration (Shankar, 2009). This condition gradually manifests itself in the form of pain as one is carrying a heavy load. However, the severity of the condition varies from one individual to the other. Disc degeneration has become a relatively common concern among ...

What happens with a patient who develops a cataract?

A cataract is the opacification of the crystalline lens in the eye. In a patient with cataract, there is progressive loss in the transparency of the crystalline lens; this is due to changes in the density of the epithelial cells. There is also a derangement in the fiber of the lens cells. Lens transparency can also be because of deposition of minute epithelial masses of apoptotic lens tissue in the substance of the lens leading to disruption of the internal homeostatic mechanism of the lens and accelerating the process of cataract formation. (Vincente Ocampo, 2012)

Cataract initially leads to an increase ...

Senses and Others: Organs Systems of the Body

An organ system is a group of organs working together to perform a specific and complex function (Grabowski & Tortora, 2003). The human body is composed of 11 organ systems, all performing specific functions. This paper focuses on six organ systems, namely the integumentary system, muscular system, skeletal system, nervous system, endocrine system, and the sub-system sensory system.

The integumentary system is the system that is composed of glands, hair, nails, and the body’s largest organ: the skin. The system’s main function is to protect the other organs from invasion of harmful bacteria, viruses, and chemicals, as well as ...

a) Explain why the effort of hormonal (Endocrine ) control tends to be slow whereas nervous control is usually very fast.

Endocrine control is normally slower when compared to nervous control majorly because hormones once released by the endocrine gland have to travel via the circulation to reach their target receptors on the effector organ which generally takes more time. Meanwhile, information relayed by nerves is in form of impulses (that is, action potentials generated due to electrical excitation produced by a change in the charge across the surface membrane of the neuron evoked by the stimuli) that simply travel along the ...
