Nervous System Case Studies Samples For Students

Part 1

Imagine you are being chased through the woods by a hungry bear. Which nervous system would engage? (Parasympathetic or sympathetic) Why is this?
The nervous system of a human being is categorized into two major parts, the first one being the peripheral nervous system, which comprises the autonomic nervous system, the somatic nervous system and the cranial and peripheral nervous system. The second major part is the central nervous system which made up of the brain and the spinal cord.
The autonomic nervous system (ANS) plays the fundamental role of controlling the spontaneous or involuntary body functions. Such functions ...

Multiple sclerosis

Introduction
In order to understand the situation to be addressed and discussed in this case study, it is necessary to start by understanding the medical condition in question. Also referred to as disseminated sclerosis, multiple sclerosis is an inflammatory disease, commonly found in young adults, which leads to the damage of the accumulated fatty sheath of myelin, in which case, demyelination results. Demyelination is the occurrence of diseases of the nervous system, which comes as a result of the scarring of the myelin fat, leading to impaired conduction and coordination of the nerves. At the same time, it is ...

Introduction

Bacterial meningitis is an infection that affects the meninges, the cerebrospinal fluid and the spinal cord that causes death and disability in a number of people worldwide. This is a highly contagious airborne disease that is spread through the transmission of three organisms present in the respiratory secretions: Neisseria meningitides, Haemophilus influenzae, and Streptococcus pneumoniae. The onset or origins of the disease varies among different age groups and geographic locations. According to estimates, 200,000 people die annually of meningitis. Case fatality rates vary with age at time of illness and also depend on the particular bacterial strain causing the infection ( ...

Introduction

A stroke is a medical condition which is characterized by rapid loss of brain function which is caused by interruption in the blood supply to the various parts of the brain. It can be due to a blockage and it’s known as thrombosis or lack of blood flow known as ischemia or a leakage of blood that is hemorrhage (Feigin, 2005). It results in the person’s inability to move certain parts of the body.
The brain is designed in such a way that the right hemisphere always controls the left side of the body while the left hemisphere controls the ...

Describe how a nerve impulse is transmitted from one neuron to the next

The transmission from one neuron to another is characterized by exchange of electric charge across the membrane of each neuron (Fields, 2014). An unstimulated neuron would be polarised (McCance 2014). In the polarized state, there is difference in the electric charge across the membrane. However, during exchange, a neuron is said to undergo polarization, wherein there is an excess of Na+ (sodium ions) outside and excess of K+ (potassium ions) on the outside (Fields, 2014). Nerve impulse is transmitted through the process of polarization, repolarization, and hyperpolarization (McCance 2014).

1.Diaphoresis is a medical condition of the body that an individual often sweats because of a drug side effect or symptom of a disease. Motor dysfunction has associations with the nerve and muscle center responsible for movement; this term defines the improper functioning of the muscle. Cyanosis is a condition related to the low supply of oxygen in the blood where the skin color of an individual as well as mucous membranes appears to have purple or blue coloration. The peripheral nerve connects the central nervous system and the brain to the entire body neurons; any damage or pressure ...

Introduction

The aim of this paper is to present a comprehensive report on a case study conducted on an individual who is displaying symptoms of hypertension. The paper explicitly explores as a chronic disease and some of the aspects that will be touched on include its epidemiology, Pathophysiology, differential diagnosis, treatment plan, drug analysis and follow up care.
Hypertension, also commonly referred to as high blood pressure is a body condition in which blood vessels, specifically the arteries high and persistent pressure. This high pressure makes it hard for the heart to pump blood to all the other parts of the body. Hypertension ...

The issue/ problem

The case concerns Mr. A. His medical condition relates to terminal cancer that is affecting his lower spine and pelvic bones. The problem with his condition is the complexity of the situation. The patient has decubitus ulcers since the skin around his pelvic bones has developed bed sore and pressure sore. At one point, nurses do not know whether to keep on turning him to avoid any further skin breakdown while other nurses insist that he has to remain in the present position to stop causing pain to the patient. Also, it is critical since Mr. A has a ...

Any person who is suddenly withdrawing from alcohol must experience unpleasant reactions that accompany the process. The abrupt withdrawal brings about certain signs and symptoms that characterize the sudden discontinuation of taking drugs or alcohol. Some of the symptoms may include a rapid heartbeat, profuse sweating, temporary memory loss, insomnia, headaches, anxiety and even social isolation (Miller & Gold 1998). Most people who experience similar reactions as a result of sudden withdrawal from alcohol suffer from delirium tremens (DT) (Koob 2006).
It is one of the most prevalent risk factors in this case. The patient often experiences DT after 48-96 ...

A brief account of the patient/client assessment

Drug misuse within state prisons has persistently been a major problem for the healthcare personnel. The treatment of misusers within these units is however a challenge for those concerned and this is attributed to a host of factors which dependently or independently leads to fragmented measures of managing this population. These challenges range from the vulnerability of the prisoners to self-harm and suicide cases while in prison; the occurrence of death upon serving their term due to intentional or accidental opiate overdose; the lacking measures of counseling as part of an integrated withdrawal system; the non-adherence to national and ...

Abstract
Asthma is a chronic problem that influences lung function. Clinically asthma is identified by the variation in expiratory airflow and abnormal respiratory symptoms such as wheezing, chest congestion, cough, and shortness of breath. The aetiology of asthma is linked to a mixture of genetic and environmental factors, though; heredity or atopy also plays a role in asthma. Asthma is categorized into two types: extrinsic (allergic) and intrinsic (nonallergic). Allergic asthma is an outcome of the reaction of an antibody ...

Overview

The second half of summer, 1982. Five women were found strangled to death at the Green river banks in King County, Washington. During the investigation, the detectives found out that all they were prostitutes. They were working nearby. All the women were announced to be lost for some time already. This was only the beginning. In the next several years, more and more girls have been found along the Green River banks and in the woods nearby. If the first five murders made investigators suspect a serial killer in the King County, now there was no doubt about that. Sometimes ...
