Vedclass · Answer

(A) The stimulation of a muscle fiber by a motor neuron occurs at the neuromuscular junction (also known as the motor end plate).This is a chemical synapse between a motor neuron and a muscle fiber.When an action potential reaches the axon terminal of the motor neuron,it triggers the release of the neurotransmitter acetylcholine into the synaptic cleft.This neurotransmitter binds to receptors on the sarcolemma of the muscle fiber,initiating an action potential that leads to muscle contraction.

Stimulation of a muscle fiber by a motor neuron occurs at:
