Question

Somatic motor and autonomic neurons are?

1) Efferent neurons of the CNS
2) Efferent neurons of the PNS
3) Afferent neurons of the PNS
4) Afferent neurons of the CNS

Answer 1

Somatic motor and autonomic neurons are 2) efferent neurons of the PNS. Motor neurons carry instructions from the CNS to the muscles, forming efferent fibers. Both the autonomic and somatic nervous systems include sensory and motor neurons.

Step-by-step explanation:

Somatic motor and autonomic neurons are efferent neurons of the PNS. Motor neurons, carrying instructions from the CNS to the muscles, are efferent fibers. The autonomic nervous system and the somatic nervous system both interact with the CNS and include sensory and motor neurons.
