b) ptosis
c) APD
d) EOMS
e) diplopia
f) contrast sensitivity
g) muscles of facial expression
h) visual fields
i) pupils
j) color vision
k) facial nerves

Answer 4

a) vision loss–afferent
b) ptosis–efferent
c) APD–afferent
d) EOMS–efferent
e) diplopia–efferent
f) contrast sensitivity–afferent
g) muscles of facial expression–efferent
h) visual fields–afferent
i) pupils–efferent
j) color vision–afferent
k) facial nerves–efferent

**sensory=afferent, motor=efferent
