Question

multiple choice question
which efferent pathway has a single nerve fiber extending from the cns to effector?
autonomic
visceral
somatic

Explanation:

The somatic efferent pathway has a single nerve fiber extending from the CNS (central nervous system) to the effector (skeletal muscle). In contrast, the autonomic efferent pathway has a two - neuron chain (preganglionic and postganglionic neurons). The term "visceral" is more of a general description related to internal organs and is not as specific as "somatic" in answering this question about the structure of the efferent pathway.

Answer:

Somatic
