Exam 20: Central Nervous System

The central nervous system includes all of the nervous system except the peripheral nervous system.

The most superficial border of the subarachnoid space is the dura mater.

The epidural space contains a layer of fat and other connective tissue.

Funiculi consist of tracts divided into smaller bundles called nerve fibers.

Match each landmark of the brain with its description or location. -General term for a convolution or raised area on the cortex

The hypothalamus is able to influence the functioning of both the sympathetic and parasympathetic divisions of the autonomic nervous system.

The body's biological clock is controlled by the:

The islands of gray matter inside the hemispheres of the cerebrum are known as the cerebral cortex.

The location of the crossing of the left and right optic nerves is called the epithalamus.

The thalamus is responsible for the associating sensory impulses with feelings of pleasantness and unpleasantness.

Formation of the cerebrospinal fluid occurs mainly in the choroid plexus.

Match each landmark of the brain with its description or location. -Divides the cerebrum into right and left hemispheres

What structure drains cerebrospinal fluid into the third ventricle?

Cerebrospinal fluid is absorbed into the venous blood via the choroid plexus.

The meninges are protective coverings, continuous around the brain and spinal cord.

The thalamus acts as a relay station for ascending sensory impulses.

The central nervous system includes the brain, spinal cord, and autonomic nerves.

For voluntary skeletal muscle activity, impulses originate in the cerebrum but coordination of the activity is a function of the cerebellum.

There are _____ ventricles in the brain.

The cerebellum coordinates both incoming and outgoing motor information.
