In motor pathways,axons of lower motor neurons exit the _________ and project to the __________ to be innervated.
A)CNS; skeletal muscle
B)PNS; skeletal muscle
C)CNS; sensory receptor
D)PNS; sensory receptor
E)CNS; PNS

Question

Quizplus · Accepted Answer

Lower motor neurons are located in the spinal cord and brainstem, which are part of the central nervous system (CNS). The axons of these neurons exit the CNS and project to the skeletal muscles in the periphery of the body (not sensory receptors). Therefore, the correct choices are A and B. However, B is not the best choice as it includes the term PNS, which refers to the peripheral nervous system as a whole (including sensory receptors), while only the skeletal muscles are targeted in this case.
