Question

a&p flix quiz: events at the neuromuscular junction 6 parts 0.33 of 1 point part c (3 of 6) 2 tries left action potentials travel the length of the axons of motor neurons to the axon terminals. these motor neurons arise in the epimysium of a skeletal muscle and extend to individual skeletal muscle fibers extend from the brain to the sarcolemma of a skeletal muscle fiber extend from the brain or spinal cord to the sarcolemma of a skeletal muscle fiber extend from the spinal cord to the sarcolemma of a skeletal muscle fiber

Explanation:

Motor neurons that transmit action - potentials to skeletal muscle fibers originate in the central nervous system (brain or spinal cord) and extend to the sarcolemma of the skeletal muscle fiber. They do not just arise in the epimysium of a skeletal muscle.

Answer:

extend from the brain or spinal cord to the sarcolemma of a skeletal muscle fiber
