Nicotinic acetylcholine receptor

In class, we’ve talked about the myosin when seeing the microfilament. It is the motor protein of microfilament which moves along it tracks toward the positive end. It is also the major component of skeletal muscle thick filaments and thus, is involved in muscle contraction. The disease that is going to discuss is related to muscle contraction, called Myosin Storage Myopathy (also known as hyaline body myopathy). The characteristic or symptom of this disease is the weakness of the muscles that…

activated and then will release acetylcholine. This causes the acetylcholine to bind to the nicotine receptors that will cause the receptor to open a channel by changing shape, which allows sodium to flow into the cell. Once full, there is an action potential that that travels down the nerve, which leads to signals that allow acetylcholine to be released; however not all these cells arrive at the listening cell to be cut by the acetylcholinesterase or bound to muscarinic receptors, some wander…

pocket formed around the end of a motor neuron by the sarcolemma, or the cell membrane of a muscle cell. Each motor end plate is mitochondria-dense because a lot of energy is needed for the release and re-uptake of the neurotransmitter acetylcholine. Once acetylcholine crosses the…

Demographic Information For this assignment I watched Still Alice (Glatzer, 2015). This movies main character is Alice who is a linguistic professor at Columbia University. At the begging of the move she is celebrating her 50th birthday. She is married to John and has three adult children Anna, Tom, and Lydia. After having some issues with her memory Alice decides to see a neurologist who tests her cognitive abilities and does scans of her brain. After the test are performed Alice is diagnosed…

Alzheimer’s is a form a dementia where the brain begins to deteriorate, causing the decline of memory in middle to older aged individuals. Although there are treatments that slow the progression of Alzheimer’s and soften the symptoms of the disease, there are still no cure. Alzheimer’s only continues to worsen as a person diagnosed with the disease continues to grow older. Approximately 4.5 million Americans are affected by Alzheimer’s disease at the current date (Alzheimer 's Disease Center).…

Alzheimer’s disease. The medications that have been approved by the Food and Drug Administration (FDA) for Alzheimer patients are cholinesterase inhibitors and memantine. Cholinesterase inhibitors prevent the breakdown of the neurotransmitter acetylcholine, which is the neurotransmitter associated with memory and thinking, and delay the worsening of symptoms for 6 to 12 months. This type of medication is usually prescribed to patient’s in the early to moderate stages of the disease. The most…

The sympathetic nervous system is a faster system as it moves along very short neurons, but when the system is activated, it initiates the adrenal medulla to release hormones and chemical receptors into the bloodstreams. In turn, the target glands and muscles are activated. Once the perceived danger is gone, the parasympathetic nervous system takes over to counterbalance the effects of the sympathetic nervous system 's responses. The flu for…

disease. The immune system produces immunoglobulin G antibodies against voltage-gated calcium channels (VGCC) residing on the cell membrane of the presynaptic nerve ending.1,3,5,6 The etiology of LEMS is decreased exocytosis of the neurotransmitter acetylcholine from presynaptic neurons into the neuromuscular junction (NMJ) caused by autoantibodies attacking VGCCs.3,7.10 There are two distinct groups of LEMS patients: those with small cell lung carcinoma (SCLC) and those without SCLC. SCLS is…

It is estimated that up to 80% of acetylcholine receptors may be destroyed by this disease. It is believed that the thymus gland causes the body to develop immune cells, and causes the production or maintains the production of antibodies that block the acetylcholine receptors. Therefore, causing the immune system to attack its own cells, tissues and specifically the acetylcholine receptors, making Myasthenia Gravis an autoimmune disorder. Myasthenia Gravis is…

Alzheimer’s is cellular disease that affects your neurons. The neurons are the cells in your brain, which forms a network of communication with other surrounding nerve cells. This helps transmit signals throughout the body. Alzheimer’s is a very serious and emotionally excruciating disease. While many diseases wound people physically, Alzheimer’s is a disease that takes away persons inner self. In other words, Alzheimer’s robs a person of their mentality, self-respect and free-choice.…
