The Neurotransmitter Released from the Motor Neuron at a Neuromuscular

Question

The neurotransmitter released from the motor neuron at a neuromuscular junction is
A)norepinephrine
B)acetylcholine
C)adrenaline
D)calcium
E)glycine

Accepted Answer

Acetylcholine is the neurotransmitter released from the motor neuron at a neuromuscular junction. This neurotransmitter binds to receptors on the muscle cell, leading to muscle contraction. Norepinephrine and adrenaline are neurotransmitters for the sympathetic nervous system, while calcium is an ion necessary for muscle contraction, but not a neurotransmitter. Glycine is an inhibitory neurotransmitter in the spinal cord.
