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, ...

ANATOMY OF URINARY TRACT INFECTIONS

The urinary tract, simply put, is the bodies system of drainage through which excess water and wastes are removed from the body. It is a multi-organ system consisting of the two kidneys, two ureters, the bladder and the urethra. The kidneys are small organs that assume the shape of a bean and are equivalently the size of a normal human fist. They are located below the rib cage, each of them on either side of the spine. Wastewater (urine) moves from the kidneys downwards through two narrow tubes known as ureters, and it is then stored in the bladder, ...

The overhead football throw is one of the most popular sports movements amongst young males in America. It is an overhead throw with a football, which quarterbacks make when they throw the ball, usually for a great distance. Due to the shape of the ball, it should also have a particular twisting pattern so that the throw may be more accurate and fast. The main joints involved are the elbow and the shoulder, so it is important to take them into account when discussing the motion’s biomechanics. The starting position of the movement is simply standing up, with ...

Final Test

Explain in general terms the process of DNA replication. The replication of the DNA starts when the double helix unwinds. Each of the two strands serves as the template using which the new DNA double helix strands are formed. The different bases on each of the two strands are then matched in order to form a new set of two strands. Each of the new strands partners with the parent strand to form a double helix (Roth 26).

Prophase – Chromatids are joined at the centromere. Spindle formation occurs. The separation of centrioles occurs in animal cells (Tobin and Jennie ...

1. Explain in general terms the process of DNA replication. DNA replication refers to the process whereby DNA makes its own copy during the process of cell division. During this process, the DNA strands unzip themselves since helicase enzyme breaks the hydrogen bonds between the complementary strands. As this occurs, a replication fork is created. Each individual strand (leading and lagging) will be used as templates. A primer attaches itself to the leading strand and the synthesis of DNA begins, whereby DNA polymerase adds nucleotides to the synthesized strand. This is a continuous process and occurs in 5’ to ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Compare and contrast the structure and function of the three simple tissue types: parenchyma, collenchyma, and sclerenchyma.

Parenchyma cells refer to plant cells in the leaf that are usually alive at maturity. They have cell walls that are thin and flexible. They generally have a central vacuole that is large. They have a polyhedral arrangement. They are involved in carrying out photosynthesis, storage functions, and other metabolic functions. Most of these cells have the potential to undergo differentiation generating other cell types in certain conditions. For instance, when the plant is injured and there is a need for repairing and replacing organs. Their large central vacuoles enable them to store water, regulate intake of ions 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 ...

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 ...

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 ...

In most cases when we think of pollution very rarely do we spare a moment or two to think of ecological footprints of the shoes on our feet, the cap on our heads nor the shirts on our backs (Claudio). Instead, all we think of is the raw sewage piped into our watercourses; we envision the emissions from the textile and coal industries, our bare-stripped forested landscapes, and the municipal wastes piling on our streets and landfills (Sweeney). The bitter and unfortunate truth, however, is that the overall impact of the apparel industry on our plant is quite grim ( ...

Introduction

A fossil is any substance that evidences a once-living organism (University of Arizona, 2016). As such, fossils evidence the ancient life forms which inhabited the earth long time ago and were preserved by a natural process. Most of the fossils are found in sedimentary rocks formed from the sediments of rivers, seas, and lakes. Some of these fossils are actual remains of living things such as bones, or events that happened in the past, for instance, the dinosaur footprints. However, it is ordinarily the hard parts of organisms that get preserved under the right conditions and the interaction of ...

Diverticular is a disease that involves the appearance of pockets or small bulges in the intestine walls (NHS, 2016). The pockets may become infected or inflamed resulting into diverticulitis. Some of the symptoms of diverticular include bloating; and pain in the lower abdomen. Many people who suffer from diverticular do not exhibit any symptoms. In such a case the condition is referred to as diverticulosis. On the other hand, diverticulitis has some serious symptoms that include fever; diarrhea; and severe pain in the abdomen. The diverticular disease occurs on the walls of the colon. The responsibility of the colon ...

ABSTRACT

Pilot uniforms, particularly in the commercial airline industry, conveys professionalism, competence, and experience. However, historically, uniforms started as a component of safety in aviation, which relied not just in their protective functions but as well in their capability to protect combat pilots from the natural elements of extreme heat and cold, particularly during the era of open cockpits. Protective flight clothing has evolved significantly through decades and even centuries. The sophisticated development in protected flight clothing, however, failed to influence adaption in the civil air transport industry. Using grounded theory through archival literature analysis, the Capstone Project revealed advantages ...

Rhabdomyolysis

Introduction In normal conditions, muscles grow when certain activities cause the muscle fibers to become damaged and then subsequently regrown and developed through a series of cellular process. This activity occurs during the body is at rest. In other words, the continuous breakdown is normal for growing muscles as it allows them to become bigger through the introduction of myrofibrils, or muscle fibers. However, there is a condition when the muscle fibers break down rapidly due to a number of reasons, and then they do not regrow at a corresponding rate. This condition is known in medical circles as ...

The foods that provided carbohydrates in my recorded daily intake included whole grain meal, cheese, yogurt, lettuce, and grapes.

Melt spinning refers to a method that is used to cool liquids in a rapid manner. The method involves the internal cooling of a wheel using liquid nitrogen or water. The wheel is then rotated as it cools. A liquid is streamed onto the cooling wheel, and that causes it to solidify rapidly. Melt Spinning is used in the development of objects that demand high cooling rates for them to form. A good example of such material is metallic glass. Polymers that can undergo melting use the melt spinning technique (NPTEL, 2010). Examples of such polymers include polyester; sulfur; ...
