Exam 15: The Nervous System: the Brain and Cranial Nerves

Which of these statements concerning the glossopharyngeal nerve is incorrect?

The parasympathetic nervous system is characterized by

Gray rami communicantes contain sympathetic fibers that travel to peripheral structures.

Division of the ANS responsible for the fight-or-flight response describes the

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.

Parasympathetic ganglia that are located within the walls of the innervated organs are called

The cardiac center of the medulla oblongata regulates the diameter of blood vessels.

Parasympathetic fibers innervate the sweat glands, arrector pili, and smooth muscles of the arteries.

Postganglionic sympathetic fibers release norepinephrine and are called cholinergic fibers.

Autonomic fibers to the pelvic organs pass through the pelvic plexus, also known as the plexus.

Parasympathetic postganglionic fibers of the head travel within the

The secretions of the adrenal medulla act to supplement the effects of

Parasympathetic stimulation of blood vessels causes vasoconstriction and increased blood pressure.

Vasoconstriction and bronchodilation result from stimulation by the division.

A descriptive term that identifies the type of neurotransmitter released by sympathetic postganglionic fibers.

The adrenal medulla is comprised of modified sympathetic neurons which secrete epinephrine and norepinephrine.

All of the following plexi contain fibers from the vagus nerve except

Network of autonomic axons giving rise to nerves of the pelvic organs.

Which of these is not innervated by the ANS?

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