Question

the motor end plate is the
a the location on a muscle cell that has chemically gated channels.
b the location on a muscle in which a nerve can communicate with.
c both of these are true.
d neither of these are true.

Explanation:

The motor end - plate is a specialized region of the muscle cell (sarcolemma). It contains chemically - gated ion channels (such as those for sodium). When neurotransmitters (e.g., acetylcholine) bind to receptors on these channels, they open, allowing ions to flow. This is the site where the nerve (motor neuron) communicates with the muscle cell (the neuromuscular junction). So both statements in options A and B are correct.

Answer:

C. Both of these are true.
