17
Q

General Somatic Afferent Fibers

A

pick up stimuli from surface of body (pain, temperature, pressure). Found in CN V and all spinal nerves

18
Q

Special Somatic Afferent Fibers

A

special senses (vision, audition). Found in CN II (eye) and CN VII (ear)

19
Q

General Visceral Afferent Fibers

A

pick up stimuli from walls of blood vessels and visceral organs. Chemical stimuli. CN VII, CN IX, CN X, and all spinal nerves

20
Q

Special Visceral Afferent Fibers

A

taste and smell. CN I = smell. CN VII, CN IX, and CN X = taste

21
Q

Proprioception

A

sensory. Body can detect position of the head, limbs, and trunk
