Neurotransmitter Molecules are Stored in Vesicles Within

Question

Neurotransmitter molecules are stored in vesicles within
A) myofibrils.
B) motor units.
C) motor end plates.
D) motor neuron endings.
E) sarcomeres.

Accepted Answer

Neurotransmitter molecules are stored in vesicles located at the endings of motor neurons, also known as motor neuron endings. These vesicles release neurotransmitter molecules into the synaptic cleft, where they bind to receptors on the muscle fiber and initiate muscle contraction.
