Homework Answers
Acetly choline is a neurotransmitter which is a chemichal produced at the nerve endings act as a neurotransmitter .it is an ester of the acetic acid and choline . It is produced at the neuromuscular junction . In brain it act as the neuromodulator which alters the chemichal structure .it is released at the neurons and enters at the synaptic cleft .
answer ; SYNAPTIC CLEFT

Draw (by hand) the steps involved in the release of acetylcholine (Ach) from a preganglionic nerve into the synaptic cleft Your drawing should include: a presynaptic nerve with an drawing/explanation of an action potential A drawing/explanation of the process by which Ach is released into the synaptic cleft A drawing/explanation of what type of receptor Ach binds with (on the post synaptic nerve) An explanation of how the body degrades/recycles Ach How is Ach involved in myasthenia gravis? Write 2-3...

Sequence of Events at the Neuromuscular Junction The site where a motor neuron excites a skeletal muscle fiber is called the neuromuscular junction. This activity will test your understanding of the sequence of events that occur at the neuromuscular junction. Using the images for help, place in the correct order of occurrence from left to right the events that occur at the neuromuscular junction after the action potential reaches the axon terminal. Termination of Neural Transmission Which of the following...

90) The motor end plate is A) the same as the neuromuscular junction. B) formed by the membrane of enlarged axon terminals, or boutons, that lie on the surface of skeletal muscle cells. C) a special fibrous matrix whose collagen fibers hold the axon terminal in proper position. D) a folded area of muscle cell membrane with ACh receptors clustered at the top of each fold. E) the same as the synaptic cleft.

1. What channels or carriers are NOT found at the axon to the axon terminal? Select one: a. Na+ leaky channels b. Cl- gated channels c. Na+ gated channels d. Na+-K+ ATPase e. None of the above 2. What is TRUE about action potential in the neuron? There may be more than one answer. Select one or more: a. At resting membrane potential (-70mV), the inactivation gate of the Na+ channel is closed while the activation gate is opened. b....

Part I—The Hospital At last the day had come. Mr. Th ompson was having his wisdom teeth removed. He was tired of the aches and pains and the sight of his puff y face in the mirror every morning. He felt helpless, lying on the gurney watching the ceiling lights whiz by as he was being wheeled to surgery. Mr. Th ompson had selected this particular oral surgeon because of the sign outside his practice that read: “We cater to...
