Term
3 Major Layers of the Nervous System
Definition
Cerebrum, Cerebellum, Brain stem
Term
Cerebrum
Definition
controls higher cognitive functions (problem solving, speech, memory)
Term
Cerebellum
Definition
posture, coordination, motor response
Term
Brain stem
Definition
breathing, BP, heart rate, consciousness
Term
Central Nervous system components
Definition
Brain and spinal chord (both have a bony structure around them to protect them)
Term
Peripheral Nervous system components
Definition
Nerves running out beyond the spinal chord (between central nervous system and body tissues, unprotected)
Term
Concussion
Definition
a temporary brain disfunction or loss of consciousness following a blow to the head
Term
Contusion
Definition
a bruising of brain tissue
Term
Hemorrhage/Hematoma
Definition
Bleeding in the brain (can be a result of contusion)
Term
Regular Nervous System Function Requires...
Definition
Intact central and peripheral nerve pathways, uninterrupted perfusion of the central nervous system with oxygenated blood
Term
Increased Intracranial Pressure (ICP) causes
Definition
head trauma, stroke, HACE (High Altitude Cerebral Edema) or brain tumor
Term
Increased Intracranial Pressure (ICP) assessment
Definition
MOI, abnormal consciousness/MS, vomiting (esp. persistently), headache, seizure, unequal pupils (late sign)
Term
Increased Intracranial Pressure (ICP) treatment
Definition
None
Term
Concussion assessment
Definition
brief loss of consciousness (events), lapse of memory, disorientation (person, place, time), nausea, dazed or sleepy
Term
Concussion Red-Flags
Definition
decline in consciousness/MS, vomiting, severe headache
Term
Concussion Treatment
Definition
monitor for increased ICP
Term
Seizure Definition
Definition
uncoordinated electrical bursts in the brain
Term
Seizure Causes
Definition
head trauma/ICP, epilepsy, drugs
Term
Seizure Assessment
Definition
Generalized tensing of all body muscles, repetitive purposeless movement, incontinence of feces and urine, unresponsive even with open eyes
Term
Seizure Treatment
Definition
protect the patient while the patient is seizing (protect head and spine), position and ventilate the patient (if patient does not begin breathing within 2 minutes), open and clear airway after seizure
Term
Spinal Chord Trauma Assessment
Definition
MOI, pain or tenderness in the spine, decreased circulation, sensation and motion, deformity
Term
Spinal Chord Trauma Treatment
Definition
Immobilize
Term
Peripheral Nerves Causes
Definition
Trauma or pressure
Term
Peripheral Nerves Assessment
Definition
Decreased CSM beyond the site of the injury/pressure
Term
Peripheral Nerves Treatment
Definition
Remove Pressure
