CH 10: Part II

fluid circulating in and around the brain and spinal cord

column of nervous tissue, nerve conduction to and from the brain and the body

• three membranes that cover the brain and spinal cord
• dura mater, pia mater, and arachnoid

• nerves that branch from the CNS-crainal nerves and spinal nerves
• cranial nerves: 12 pairs
• spinal nerves: 31 pairs

nerves conducting impulses from body parts to the brain

nerves conducting impulses from the brain to muscles

involuntary-smooth & cardiac muscle + glands

control center for the ANS

• both part of ANS
• sympathetic: fight or flight
• parasympathetic: rest and digest

without speech

difficulty speaking

difficulty articulating-incoordination of motor (muscle) speech

decreased consciousness

• mental confusion, disturbances of cerebral function
• from: fever, shock, OD, etc.

• impariment of intellectual function
• memory loss, disorientation, confusion

loss/impairment of muscle function

loss/impairment of sensation

pain along a nerve

temporary or permanent loss of motor control

flabby, defective, absent muscle control caused by a nerve lesion

stiff and awkward muscle control caused by central nervous system disorder

partial paralysis of the Right or Left half of the body

pain that follows the pathway of a sciatic nerve

sudden disturbance of brain function resulting from abnormal firing of nerve impulses

to pull together; type of seizure that causes a series of sudden, involuntary contractions of muscles

fainting

increased sensitivity, ex: to touch or pain

abnormal sensation of numbness/tingling without cause

loss of neruological function associated with interpretation of sensory information

• disease of structural changes in the brain
• forgetfullness, disorientation, loss of intellectual function, death

• deterioration of motor nerve cells leading to total loss of voluntary muscle control.
• Lou Gehrig disease

• motor dysfunction due to damage of the cerebrum during development/birth injury
• characteristics: partial paralysis & lack of muscle coordination

disorder-change within one or more blood vessels of the brain

hardening of the arteries of the brain

fatty plaque buildup within the vessels of the brain

dilation of blood vessels in the brain

having a stationary blood clot in a vessel of the brain

obstruction of a blood vessel int eh brain by an embolus transported through the circulation

• stroke
• damage to the brain caused by a cerebrovascular disease-embolus, hemorrhage...

brief episode of loss of blood flow to the brain-caused by partial occlusion

inflammation of the brain

recurrent seizures, affecting CNS

• type of epilepsy
• stiffening-jerking-a MAJOR motor seizue (aka grand mal)

tumor of glial cells

protrusion of intervertebral disk so that the nucleus pulposus protrudes-compressing root

• viral disease, shingles
• affects peripheral nerves, causing painful blisters
