The cavities found in the brain are called ______.

Ventricles contain ______.

A _______ is an elevated ridge of cerebral cortex tissue.

The convolutions seen in the cerebrum are important because they increase the _________.

Gray matter is composed of ________.

White matter is composed of _______.

The lentiform nucleus, the caudate, and other nuclei are collectively called the _________.

site of regulation of water balance and body temperature

contains reflex centers involved in regulating respiratory rhythm in conjunction with lower brain-stem centers

responsible for the regulation of posture and coordination of skeletal muscle movements

important relay station for afferent fibers traveling to the sensory cortex for interpretation

contains autonomic centers which regulate blood pressure and respiratory rhythm, as well as coughing and sneezing centers

large fiber tract connecting the cerebral hemispheres

connects the third and fourth ventricles

encloses the third ventricle

forms the cerebrospinal fluid

midbrain area that is largely fiber tracts; bulges anteriorly

part of the limbic system; contains centers for may drives (rage, pleasure, hunger, sex, etc.)

the primary sensory area of the cerebral hemisphere is found in the __________ gyrus

cortical areas involved in audition are found in the __________ lobe

the primary motor area in the ______ lobe is involved in the initiation of voluntary movements

a specialized motor speech area located at the base of the precentral gyrus is called _______ area

the right cerebral hemisphere receives sensory input from the ______ side of the body

the __________ tract is the major descending voluntary motor tract.

damage to the ________ impairs consciousness and the awake/sleep cycles

A ______ EEG is evidence of clinical death.

Beta waves are recorded when an individual is awake and _________.

outermost covering of the brain, composed of tough fibrous connective tissue

innermost covering of the brain; delicate and vascular

structures that return cerebrospinal fluid to the venous blood in the dural sinuses

middle meningeal layer; like a cobweb in structure

its outer layer forms the periosteum of the skull

slight and transient brain injury

traumatic injury that destroys brain tissue

total nonreponsiveness to stimulation

may cause medulla oblongata to be wedged into foramen magnum by pressure of blood

after head injury, retention of water by brain

results when a brain region is deprived of blood or exposed to prolonged ischemia

progressive degeneration of the brain with abnormal protein deposits

autoimmune disorder with extensive demyelination

a mini-stroke; fleeting symptoms of a CVA

the spinal cord extends from the ________ of the skull to the ________ region of the vertebral column.

the procedure of withdrawing cerebrospinal fluid without damage to the spinal cord is called

______ pairs of spinal nerves

_______ pairs of cervical nerves

______ pairs of thoracic nerves

______ pairs of lumbar nerves

________ pairs sacral nerves

the tail like collection of spinal nerves at the inferior end of the spinal cord is called the

Fiber type in the ventral root

Fiber type in the dorsal root

Fiber type in a spinal nerve

Cranial nerve involved in shrugging the shoulders

Cranial nerve involved in smelling a flower

Cranial nerves involved in raising the eyelids and focusing the lens of the eye for accommodation; constriction of the eyepupils

Cranial nerve involved in slowing the heart; increasing the mobility of the digestive tract

Cranial nerve involved in smiling

Cranial nerve involved in chewing food

Cranial nerve involved in listening to music; seasickness
