Nerve

This essays purpose is to contrast the mechanisms that underlie signal propagation within and between nerve cells. It is important that this is answered correctly, as the actions of the mechanisms are crucial for what is going on inside of our bodies. To begin with, the basic anatomy of the neuron has to be explained, to understand what exactly happens, and how it happens. A neuron cell is most likely the supreme cell within the body of a mammal. Like any other cell, the neuron cell has the…

Also known as the second cranial nerve, or CN II, the optic nerve is the second of twelve cranial nerves. Although located at the back of the eye, the optic nerve is considered a part of the central nervous system due to its role in visual integration and function. The optic nerve transfers visual information from the retina to the vision centers of the brain via electrical impulses. Made of about 1.7 million retinal ganglion cell axons, or nerve cells, the optic nerve encompasses the first…

react to the certain stimulus. The word neuropathy is defined as nerve damage and thus the nerves that could be referred to are motor, sensory or autonomic nerves. As a result, symptoms can range anywhere from numbness and tingling to paralysis or organ dysfunction depending on the type of nerves(s) that are damaged. Motor nerve damage can result in muscle damage or uncontrolled movements. Depending on the size of the sensory nerve that is damaged, patients may become over sensitive or even…

within the face. It occurs when there is a disruption of normal function in the trigeminal nerve, which sends electrical impulses of pain, pressure, temperature, and touch to the brain from the jaw, face, gums, and around the eyes. The disruption is caused by compression or damage to the trigeminal nerve, usually due to contact between the nerves and a nearby blood vessel. This contact places pressure upon the nerve, which leads to malfunction and pain. In most cases, the disorder begins as…

anatomical map of structures such as the phrenic nerve is vital for medical treatments. G.S. Muller Botha mapped the phrenic nerve and described her findings in The Anatomy of the Phrenic Nerve Termination and the Motor Innervation of the Diaphragm. Sleep apnea is a common disorder caused by under stimulation of the diaphragm from the phrenic nerve, O. Oldenburg and team described alternative treatments for the apnea in Effects of unilateral phrenic nerve stimulation on tidal volume. Lastly,…

splinting and splinting plus local steroid injection in moderate to severe carpal tunnel syndrome; A Randomized control clinical Trial Introduction Carpal tunnel syndrome (CTS) which defined as “a symptomatic compression neuropathy of the median nerve at the level of the wrist” is considered as the most common disabling neuromascular condition of the upper extremities(1,2). With an incidence rate of 276:100000 per year, it known as the most prevalent entrapment neuropathy, accounting for 90%…

Carpal tunnel syndrome (CTS) is a hand injury which occurs at wrist joint and causes several problems at this joint, such as finger numbness, pain and muscle weakness. It happens as a result of compression of the median nerve which innervated thumb, index and middle finger (ASSH, 1990). This compression is caused by pattern of hand use, fracture at wrist joint and other medical conditions, for instance diabetes, obesity and rheumatoid arthritis (NHS, 2014). There are two ways to treat carpal…

Optic Neuritis is a condition where the optic nerve, which carries visual information from the eye to the brain, becomes inflamed. Most of the damage is done to the protective myelin sheath that surrounds the nerve, which is vital for good vision. A few symptoms that occur to people who have Optic Neuritis are: distorted color vision, blurriness, pain, and even vision loss. During a routine eye exam, a doctor will look for signs of Optic Neuritis by checking the eye pressure. The eye will be…
