The Specialized Region of the Sarcolemma at the Neuromuscular Junction

Question

The specialized region of the sarcolemma at the neuromuscular junction is called the
A)syncytium.
B)varicosity.
C)fascicle.
D)motor end plate.

Accepted Answer

The specialized region of the sarcolemma at the neuromuscular junction is called the motor end plate. This is where the axon of a motor neuron makes contact with skeletal muscle and neurotransmitters are released to stimulate muscle contraction. The other options, syncytium, varicosity, and fascicle, are not specific to the neuromuscular junction.
