Exam 15: The Autonomic Nervous System and Visceral Sensory Neurons

Which one of these is solely innervated by the parasympathetic division?

Identify the pathway that correctly traces the movement of preganglionic sympathetic fibers.

Describe the correct pathway that a nerve impulse to blood vessels and hair follicles (glands and arrector pili muscles) in the dermis must travel using the following structures: ventral ramus, dorsal root, ventral root, sympathetic trunk, gray ramus communicans, white ramus communicans, and spinal nerve.
