41
cerebral cortex
outer layer of cerebrum, grey matter, higher mental function
42
thalamus
2 grey matter nuclei deep win the brain, relay sensory info to the cortex
43
cerebellum
responsible for control and coordination of skeletal muscles
44
Brainstem
breathing, heart rate, body temp
| 3 levels: Mesencephalon, pons, and medulla oblongata
45
ventricles
interconnected cavities win the cerebral hemispheres and brainstem filled w cerebrospinal fluid
46
Cerebralspinal fluid
palsma-like clear fluid circulating in and around the brain and spinal cord
47
sensory nerves
conduct impulses from body parts and carry sensory info to the brain (afferent nerves)
48
motor nerves
conduct info from brain to muscles and glands (efferent)
49
hypothalamus
control center for ANS
50
sympathetic nervous system
division of ANS that prepares body for stressful or emergency situations

any of many types of loss of neurological function associated w interpretation of sensory info
60
astereognosis
inability to judge the form of an object by touch
61
atopognosis
inability to locate a sensation properly
62
AMyotrophic lateral sclerosis (ALS)
progressive deterioration of motor nerve cells resulting in total loss of voluntary muscle control.
63
cerebral palsy (CP)
condition of motor dysfunction caused by damage to the cerebrum during development or injury at birth, partial paralysis and lack of muscle coordination
64
cerebral atherosclerosis
lipid buildup w/in blood of the brain
65
Cerebrovascular accident stroke (CVA)
damage to the brain caused by cerebrovascular disease
66
transient ischemic attack (TIA)
brief episode of loss of blood flow to the brain usually caused by a partial occlusion resulting in temporary neurological deficit

Huntington chorea
characterized by bizarre involuntary body movements and progressive dementia
71
hydrocephalus
| hydrocephaly
abnormal accumulation of cerebrospinal fluid in the b=ventricles of the brain, developmental abnormalities, infection, injury, or tumor
72
multiple sclerosis (MS)
disease of the CNS characterized by the demyelination of nerve fibers w episodes of neurological dysfunction
73
myasthenia gravis
autoimmune disorder that affects the neuromuscluar junction, causing a progressive decrease in muscle strength w activity and a return of strength after a period of rest
74

polyneuritis

79
Reflex Sympathetic Dystrophy (RSD)
abnormal function of the sympathetic nervous system in response to pain perception usually as a result of injury to an extremity, persistent burning pain, tissue edema, joint tenderness, change in skin color and temp, can lead to muscle atrophy and loss of motor function

81
electroencephalogram (EEG)
record of the minute electrical impulses of the brain used to identif neurological conditions that affect brain function and level of consciousness
82
