Exam 21: Peripheral Nervous System

Judy has sustained an injury that has damaged the vestibulocochlear nerve. This injury will have an effect on her ability to:

Match each cranial nerve with its function or description. -Sends fibers to the superior oblique muscle of the eye

Match each cranial nerve with its function or description. -Abducts the eye

Which is not true of the ventral nerve root?

Two cranial nerves, the hypoglossal and the vagus, receive branches from the cervical plexus.

Match each term with its description or definition. -Reflexes that involve cardiac muscle, smooth muscle, and glands

The knee jerk can be classified as a segmental reflex because:

What is a dermatome? What is a myotome?

Match each cranial nerve with its function or description. -Branches into three nerves: the ophthalmic, maxillary, and mandibular nerves

The lower end of the spinal cord bears the name lumbosacral plexus.

There are 62 spinal nerves.

The final efferent organ of the knee jerk reflex is the quadriceps femoris muscle.

A dermatome is the skin surface area supplied by a single spinal nerve.

The olfactory nerve, the optic nerve, and the oculomotor nerve are the only cranial nerves that do not come from the brainstem.

Match each cranial nerve with its function or description. -Fibers are widely distributed in the body; name means "wanderer"

The peripheral nervous system includes:

Based on the numbering system of the cranial nerves, cranial nerve XI would be more anterior than cranial nerve III.

All of the cervical nerves contribute to the cervical plexus.

Briefly describe the structure of the spinal nerves.

Which is(are) the neurotransmitter(s) in a somatic motor pathway?
