Because the ANS is a visceral motor system, afferent pathways are of no importance and actually are rarely found.

False

The ANS contains both sensory and motor neurons..

False

Which component of the ANS is characterized by ganglia located in or near effector organs?

parasympathetic division

Oculomotor nerves are responsible for which of the following functions?

focusing the eyes on close objects

Parasympathetic ganglia are also called __________ because of their location.

first thoracic
