True or False: Lower motor neurons synapse onto muscle.

Lower motor neurons are a critical component of the motor pathway that directly controls voluntary muscle movements. They originate in the spinal cord and extend their axons out to skeletal muscle fibers. When these neurons synapse onto muscle fibers, they release neurotransmitters that stimulate muscle contraction. This connection is essential for the execution of purposeful movements, making it clear that lower motor neurons are indeed responsible for directly innervating muscles.

Therefore, the statement is true, as lower motor neurons do synapse onto muscle fibers, facilitating the communication necessary for muscle contraction and movement. Understanding this fundamental relationship is crucial for comprehending how the nervous system controls motor functions in the body.
