Paralysis is a condition linked with the inability to move and involves loss of muscle function. It can occur due to many different reasons such as illness, poison or trauma. Flaccid paralysis and spastic paralysis are two conditions that are considered different forms of paralysis. It can be accompanied with sensory loss as well as loss of feeling. Flaccid paralysis is the loss of muscle tone. It gives rise to limp and floppy muscles that lack firmness due to loss of activity in these muscles.…

The Sensory System is a very complex System in the body. There are several paths in the Sensory System from places like the eye,ear,skin,nose,etc. to the brain. I am going to tell you about the pathways from the ear to the brain, the eye to the brain, and the nose to the brain. Also, I am going to write about three Geico advertisements I watched and explain the message from the advertisement and what personal factors might be affecting my perception of the advertisements. The sound wave path…

(Candide, 1991). As we all know, in everyday life events can not come to pass or occur without something or someone releasing an impulse or cause. For example, when neurons communicate to one another, a nerve impulse is sent across the axon. Without the nerve impulse, the axon would not be able to release the neurotransmitters. Lastly, if the…

Concussions In Sports Concussions are the most popular type of head trauma in children and adults, yet it has only been within the last few years that the understanding of what concussions are and how easily they can occur in sports and other accidents, such as a fall or a car crash, has come to the attention of coaches, parents, and medical professionals. Because the awareness of what concussions are and the effects they have on brain function has increased, the number of concussions in…

Multiple Sclerosis is an autoimmune disease that causes a disruption of the myelin sheath that insulates and protects nerve cells in the brain and spine. It is an abnormal response in the body in which the immune system’s T-cells pass from the bloodstream into the nervous system to attack the myelin sheath around nerve cells. Myelin sheath are essential to the body for the nervous system to function appropriately. They are a fatty white substance that encompass a nerve cell to form an…

Topic: Understanding the Key Aspects of the Brain and the Nervous System. The entire human body activity relies on the brain function, in this first section of this report I will try to discuss the major structures, the functions as well as the major methods of studying the brain. The brain is in charge of all body functions, such as the ability to make decisions, do activities, learning and all everyday life stuff. The brain is situated in the skull protected by brain blood fluid. In the…

The NCAA and the universities benefit tremendously from the profits the student athletes generate. Through various sources of profits the NCAA has grown to a multi billion-dollar industry. The NCAA is broken down into conferences, some of the conferences are more competitive then others. There are powerhouse programs within the conferences that groom the best athletes, get the best recruits, and compete for the most prestigious championships. As a result, these conferences get the best…

(17, 27, 28). Thus, the developing brain MR images are characterized by an inverted contrast of WM and GM as opposed to the developed brain as seen in figure 1.2. The inverted contrast is due to WM axonal growth where myelin sheath forms around the axon tracts (29, 30) (see figure 1.3) and change occurs in the cell water content as a result of decreasing both T1 and T2 times in order to avoid fetus motion (30, 31). By the completion of the myelination process, the brain tissue contrast appears…

The muscular system is the system of the body that contains smooth, skeletal, and cardiac muscle tissue. This system contains a variety of functions including movement of the body and of materials throughout the body, maintenance of posture, and heat production. Muscles are the only tissue in the body that have the ability to contract and therefore move the other parts of the body. The muscular system is important because without it, life would completely stop. Muscles produce not only…

The defining characteristic of ALS is the death of the upper and lower motor neurons in the brain, brain stem, and spinal cord of the brain. Prior to their destruction, motor neurons develop protein components in their cellular bodies and axons. These components are often combined with and combining one of the proteins associated with ALS: SOD1, TDP-43, or FUS. These components are non-amyloid aggregates. This disease has been found to contradict plaque and protein accumulation. The TDP-43…
