When a motor neuron depolarizes, an electrical current (the action potential) is passed down the nerve fiber


Question Number 1140
Question:
When a motor neuron depolarizes, an electrical current (the action potential) is passed down the nerve fiber. Upon reaching the end of the neuron, the impulse causes the release of the neurotransmitter, acetylcholine. The acetylcholine binds with receptors on the muscle membrane which are in close proximity to the neuron (the motor end plate). What type of receptors are these likely to be ?
a) ryanodine receptors
b) dihydropyridine receptors
c) nicotinic receptors
d) Ca2+ channels
e) muscarinic receptors
