Exam 14: A: Central Nervous System

The geniculate bodies are important nuclei in the hypothalamus.

Consciousness may be defined as a state of awareness of one's self,one's environment,and other humans.

The hormone released by the hypothalamus,melatonin,helps regulate the biological clock.

The central nervous system directly or indirectly regulates or influences nearly every organ in the body.

The primary motor area,located in the precentral gyrus,is thought to activate individual muscles in the hands and feet.

Besides providing protection,the cerebrospinal fluid can influence the respiratory center.

Dural sinuses function as reservoirs for cerebrospinal fluid.

After birth,the brain grows only in size,not in number of neurons.

The cerebrum is the second largest portion of the brain.

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

All spinal nerves are mixed nerves.

Under normal brain functioning,activation of the reticular formation produces consciousness.

Barbiturates and amphetamines are two drugs that can arouse the cerebral cortex.

The deepest border of the subdural space is the arachnoid membrane.

The central sulcus divides the cerebrum into two hemispheres.

Spinal reflex centers are located in the gray matter of the spinal cord.

The gray commissure joins the spinal cord to the brain.

Functions of the brainstem include language,memory,and emotions.

Both the inferior and superior colliculi contain sensory centers.

One source of the tracts entering the cerebellum and forming the inferior cerebellar peduncle is the medulla.
