cna block 7 nervous system

central nervous system CNS

the part of the nervous system which consists of the brain and spinal cord, to which sensory impulses are transmitted and from which motor impulses pass out, and which coordinates the activity of the entire nervous system

brain

an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity

TKR

total knee replacement

THR

total hip replacement

nerves

in the body, a whiteish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs

spinal cord

the cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, forms the CNS

hemiplegia

paralysis on one side of the body

parkinsons disease

a progressive disease of the nervous system marked by tremors, muscular rigidity, and slow, imprecise movement, chiefly affective middle aged and elderly

multiple sclerosis MS

a chronic typically progressive disease involving damage to the sheaths of nerve cells in the brain and spinal cord, symptoms include numbness impairment of speech and muscular coordination, blurred vision and severe fatigue

spinal cord injury

damage to the spinal cord that causes changes in its function either temporary or permanent

quadriplegia

loss of function in the leg, trunk, and arms

paraplegia

loss of function of lower body and legs

traumatic brain injury TBI

an insult to the brain from an external mechanical force, possibly leading to permanent or temporary impairment of cognitive, physical, and psychosocial functions

epilepsy

a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness or convulsions associated with abnormal electrical activity in the brain

blindness

functions of the nervous system

control and message center for the body, controls and coordinates all body functions, senses and interprets info from outside the body

major sense organs

eyes, ears, nose, tongue, skin

normal changes

slow reflexes, sensitivity of nerve endings decrease, some memory loss

reported signs

movement issues, shaking, tingling, changes to eyes and ears including vision, dizziness, and pain

peripheral nervous system

the network of nerves connecting to the CNS
