Exam 5: The Central Nervous System

Gray matter refers to regions of the central nervous system composed primarily of densely packed cell bodies, whereas white matter consists of bundles of myelinated nerve fibers.

Nerves of the autonomic nervous system control skeletal muscle responses.

Match the following structures to their descriptions. a.gray matter of spinal cord b.white matter of spinal cord c.dorsal root ganglion -Location of short interneurons involved in integration of spinal reflexes

Interneurons lie entirely within the central nervous system.

The paired facial nerves are the longest cranial nerves and they innervate face muscles, salivary glands, and tear glands.

In addition to producing cerebrospinal fluid, ependymal cells may

The CNS is comprised of the brain and ____________________.

Gray matter forms the outer layer of the brain and spinal cord, and white matter comprises most of the deeper regions.

Damage to the back of the brain could most likely adversely affect a person's

A bundle of neuron cell bodies in the CNS is a ganglion, whereas a bundle of axons in the PNS is a nerve.

Describe the location of the basal ganglia and their three primary functions.
