Select all that apply: Based on the functions of CN III, this nerve is

A.
Special sensory

B.
Somatic sensory

C.
Visceral sensory

D.
Somatic motor

E.
Visceral motor

Answer 1

The oculomotor nerve (CN III) functions as both somatic motor, controlling eye movements, and visceral motor, with parasympathetic fibers for pupillary constriction and lens accommodation.

Step-by-step explanation:

Based on the functions of CN III, the oculomotor nerve, this nerve is:

• D. Somatic motor – CN III controls most of the extrinsic eye muscles that contribute to eye movements.
• E. Visceral motor – CN III contains preganglionic parasympathetic fibers responsible for pupil constriction and lens accommodation.

CN III does not have the functions related to special, somatic, or visceral sensory modalities.
