Skeletal muscles are controlled by motor neurons in the somatic branch of the peripheral nervous system, which is controlled by the central nervous system.
Neurons that carry signals from the central nervous system (CNS) to skeletal muscles are known as somatic motor neurons. These neurons are responsible for controlling voluntary movements of the body by transmitting signals that stimulate muscle contractions.
Efferent motor neurons stimulate muscle contractions.
no
Peripheral nervous system (PNS) motor neurons are responsible for controlling voluntary movements of skeletal muscles. They receive signals from the central nervous system (CNS) and transmit them to the muscles to initiate movement. PNS motor neurons are essential for activities like walking, talking, and grabbing objects.
in the CNS
A neurotransmitter is released by neurons in order to signal other neurons, muscles, or glands.neurotransmittersneurotransmitters

Motor neurons send impulses to muscles to stimulate muscle contraction. Glands are typically innervated by autonomic neurons that regulate secretions like hormones and enzymes.
acetylcholine
Skeletal and smooth muscles move when nerve impulses sent from the nervous system stimulate the muscle fibers, instructing them to either contract or relax. In skeletal muscles, this stimulation comes from motor neurons, while smooth muscle contraction is typically regulated by autonomic nerve fibers. These signals trigger a series of biochemical events that lead to muscle contraction and relaxation.
