What are the two parts of the nervous system
Central and Peripheral nervous system
What does the CNS do and involve
Central nervous system coordinated incoming information using the brain, brain stem, and spinal cord
What does the PNS do and involve
controls motor movement using the nerves
What are the five lobes of the brain
Frontal, Occipital, Parietal, Temporal, and insula lobes

brain
EEG
electroencephalography; used to measure brain activity

paresthesia
abnormal sensation (tingling)
sysesthesia
one sensation is experienced as another
caus
burn
ansomia
lack of smell
LP
lumbar puncture; puncture in lower back to remove cerebrospinal fluid
CT scan
using an xray to look for a tumor or bleeding
MRI
magnetic resonance imaging; uses magnets and radio waves to look at organs in the body
Myelogram
Xray of the spinal cord
Cerebral angiography
Xray of blood vessels of brain
PET scan
Positron Emission Tomography; uses contrasting radioactive drug infusion
MRA
magnetic resonance angiography; see blood vessels in brain via contrast
epidural hematoma
blood between skull and dura mater causing the dura mater to be pushed on
subdural hematoma
blood below dura mater
atopognosis
inability to locate a sensation
prosopagnosia
inability to recognize a fact
ictal
seizure
tonic
weak muscle tone
idiopathic
unknown origin
CVA
cerebrovascular accident; condition due to the blood vessels of the brain
hemorrhagic stroke
rupture of blood vessel to brain
ischemic stroke
lack of blood flow to the brain
TIA
transient ischemic attack; mini stroke in which blood flow is temporarily lost causing people to temporarily forget names for objects
cerebral aneursym
widening of blood vessel
cerebral arteriosclerosis
hardening of vessels
cerebral atheroscleosis
fatty plaques in vessels, can lead to arteriosclerosis
cerebral embolism
clot that traveled to the head
cerebral thrombosis
clot in the brain vessel
hydrocephaly
excess cerebrospinal fluid in brain
ALS
amyotrophic lateral sclerosis; hardening of nerve cells on the sides of the spine, loss of muscle control
