Acetylcholine has two types of receptors: muscarinic and nicotinic, these receptors are functionally and structurally different. Nicotinic receptors are ionotropic, meaning that ions flow through it when acetylcholine binds to it. It acts as a channel for the ions that cross it, especially sodium, and this causes the depolarization of the cell. There are two types of nicotinic receptors formed by different subunits, N1 are found in the neuromuscular junctions allowing muscle movement, and N2 is…
addition, changes to motor function resulting in muscle atrophy, decreased reflexes, abnormal stress to joints, and difficulty walking on toes. The most severe manifestation of motor function is muscle weakness because it can progress to total motor paralysis and death from respiratory failure (Kuwabara, 2004). Furthermore, changes to autonomic functions, resulting in will lead to difficulties gastrointestinal, genitourinary, cardiovascular, and sweating dysfunctions. Of the autonomic changes,…
Spinal muscular atrophy (SMA) is a neurodegenerative disease characterized by progressive degeneration of alpha motor neurons, leading to muscle atrophy, paralysis, and even death1 .Mostly it has a recessive inheritance; however, autosomal dominant and X-linked inheritance has been documented2 The reported incidence is about 1 in 10,000 live births with a carrier frequency of 1 in 50.3 The gene for SMA, survival motor neuron (SMN1) has been mapped on the 5q11.2-13.3 region and there are two…

If you could cure cancer, eradicate a disease or given an infertile couple a child would you? I would bet you said yes and that is what scientist have been trying to do for over 50 years with cloning. According to the American Medical Association, cloning is defined as “the production of genetically identical organisms via somatic cell nuclear transfer. ‘Somatic cell nuclear transfer’ refers to the process in which the nucleus of a somatic cell of an existing (or previously existing) organism…
Dweck's article goes in details and illustrates examples of a fixed mindset and a growth mindset . A great example provided in the article explains the two mindsets view on failing a midterm. A person with a fixed mindset will feel "utter failure and paralysis" . A person with a growth mindset would think of it as a bump in the end the road and to just work harder at it . I believe that throughout any obstacles you may have , thinking positive about a bad situation can get you to a good…

the mouse is easier to feed on, which then the ticks get infected and can infect humans. Herpes B came about in 1932, after a scientist in New York got bit by a monkey while he was researching a polio vaccine. He developed slow symptoms such as paralysis of the legs, tender lymph nodes, etc. After three days, he died. Herpes B was found to be carried by rhesus macaque, as well as other Asian monkeys. The only weird thing is that people get scratched by these monkeys all the time and never get…
of antibodies against the disease Zika. This showed that this man was more than likely suffering from Zika. The troubling thing with Zika is that people infected can go on to develop Guillain–Barre syndrome an auto-immune disease that can cause paralysis and damage nerves. The article goes on to talk about the disease Zika and the problems we face from it. Throughout the world Zika is gaining ground, traveling to other countries. With our current weapons against the disease, it is looking…
