Electrical impulses are transmitted from the motor neuron to the muscle fiber via axon terminals (also known as neuropodia or axon endfeet), to generate muscle While gamma motor neurons do not directly cause muscle contraction, they regulate the sensitivity of these muscle spindles, ensuring continuous feedback to the nervous system about muscle stretch The point where a motor neuron communicates with a muscle fiber is a specialized synapse known as the neuromuscular junction. Motor neurons, also known as efferent neurons, are nerve cells that run throughout the body and allow both voluntary and involuntary movements by innervating The structure of a motor neuron consists of a cell body, dendrites, and an axon.
