Essays About Nervous System

Parkinson’s Disease is a neurodegenerative disorder that affects predominantly dopamine-producing neurons in a specific area of the brain called substantia nigra. Parkinson’s disease is a progressive disorder of the nervous system that affects movement. It develops slowly, sometimes starting with a barely noticeable tremor in...

Amyotrophic Lateral Sclerosis (ALS) is a disease that destroys nerve cells and causes disability. The nerve cells gradually break down and die. Muscle twitching, weakness in a limb, or slurred speech is how ALS typically starts. It eventually affects the muscles needed to move, speak,...

The human brain is a magnificent system in the human body. It is the most complex, complicated, yet outstanding brilliant organ in the human body. Eric Kandel once said, “The brain is complex biological organ of great computational capability that constructs our sensory experiences, regulates...

Post-micturition convulsion syndrome sometimes called pee shudder or pee shiver is the involuntarily shiver that happens to some of us, especially men when we void a large amount of urine. This has affected most of us, especially the men but well it’s not something dangerous...

Animal behavior Animal Behavior is the scientific study of the wild and wonderful ways in which animals interact with each other, with other living beings, and with the environment. It explores how animals relate to their physical environment as well as to other organisms, and...

The central nervous system contains both myelinated and unmyelinated axons. Myelination greatly increases the velocity of action potential propagation and is associated with Hebbian learning. It acts by essentially insulating the axons that it ensheaths allowing salutatory conduction to occur. Oligodendrocytes are glial cells that...

Nervous tissue is a vital part of our nervous system. Without the nervous system, humans would not be able to function. Nervous tissue is composed of cells called neurons, which allow the body to convey messages through electrical nerve impulses. Neurons help us make sense...

Disorders and Routine Care: The Cardiovascular System – Coronary Heart Disease Effects: The organ of the heart is the main function within the cardiovascular system. When the heart developed the coronary heart disease (ischaemic heart disease) due to health issues formed by lifestyles such as...

Normal CNS Structure The skull is divided into the viscerocranium which is the facial skeleton and the neurocranium which surrounds the brain and brainstem. The neurocranium is composed of 8 cranial bones; 1 ethmoid, 1 sphenoid, 1 frontal, 2 parietal, 2 temporal, 1 occipital, their...

The Nervous system helps us control our body and works well with other systems. Some examples would be the Muscle system and the Endocrine system! Therefore, the Nervous system uses the help of these systems to gather and send information throughout the body. The Nervous...

Two or three meningeal sinuses may join to form a vestibule just before reaching the superior sagittal sinus. There is a tendency for the veins draining the lateral surface of the anterior frontal and posterior parietal regions to join the meningeal sinus in the dura...

The nervous system has numerous disorders. Though one order heard of today is a neurological disorder named epilepsy. When brain activity becomes unusual and causes a seizure that is the disorder known as epilepsy. These seizures happen unexpectedly and are different for each case or...

The experiment I have designed is intended to observe the potential impact of central nervous system (CNS) depressants on basic reading comprehension. CNS depressants come in many forms and categories, however for the sake of accuracy, the experiment would focus on one category such as...

The Nervous system is composed of two parts which then branches into more divisions, the central and the peripheral. Getting deeper into it the peripheral is then divided into two as well. The sensory division, in control of the senses and the motor division, in...

The most notable risk factor for the development of primary central nervous system lymphoma (PCNSL) is immunodeficiency [1-7]. PCNSL was historically treated with cranial irradiation, i.e., whole-brain radiotherapy (WBRT). WBRT may become complicated by the development of chronic and late neurotoxicity. In order to avoid...

Introduction Since time immemorial, animals have been seeking rewarding stimuli as it results into pleasurable sensations. In the animal kingdom, the search for rewards, such as water, food and sex amongst others, is tightly linked to survival of an individual and of the species as...

Introduction Intellectual disability (ID) is a central nervous system disease that affects 2-3 % of the worldwide population. With a wide range of sign and symptoms, three major criteria make the diagnostic picture of intellectual disability: Intelligence quotient (IQ) less than 70, present symptoms before...

The term Sciatica is described as a pain going through the distribution of sciatic nerve, commonly known as a symptom of spinal disorder and not a spinal disorder itself. Symptoms of sciatica includes pain from sciatic nerve compression which may feel dull, sharp, tingling, numbness,...

Nerve cells also are known as neurons transmit and receive electro nerve impulses. They can be found all over the body and are connected all over the body, but can mostly be found near around the Central Nervous System. They are connected to other neurons...
