Question

A single motor neuron together with all the muscle fibers it innervates is called a(n)
A) end foot.
B) end plate.
C) motor unit.
D) dermatome.
E) myotome.

Accepted Answer

A motor unit consists of a single motor neuron and all the muscle fibers it innervates. The other options are not correct - an end foot is not a recognized term in neuromuscular physiology, an end plate refers specifically to the neuromuscular junction, dermatomes refer to the region of skin innervated by a single spinal nerve, and myotomes refer to the muscle groups innervated by a single spinal nerve.
