Chapter 5 Flashcards
Peripheral nervous system
collects data. receives info such as temperature, pain light and pressure from its surroundings. it transmits it to an analytic center via special conduits known as nerves
Central Nervous System
unified collection of cells in the brain and spine.
processes the details and formulates a response.
commands are directed back to the appropriate body parts via nerves.
handles voluntary and involuntary action of the body
Somatic Nervous System
voluntary command of the body’s actions
Autonomic Nervous System
involuntary actions of the body
ex-beating heart, sweating, digesting food.

What does an image of the brain (after injury)tell us?
evaluate for bleeding to determine the presence of diseased brain tissue and to look for brain tumors
CT Scan
most common technique for getting images of the brain
complex type of Xray.
Benefit is its speed.
MRI
when a more detailed view (than a CT) is needed or when the cerebellum is of special importance, a magnetic resonance image is beneficial (MRI)
Ultrasounds
can be used to assess blood circulation to the brain and monitor the speed of blood passing through the vessels, helpful in detecting both blockages and bleeding
MRA
magnetic resonance angiography
more involved view of the vessels, dye can be injected into the blood stream and and MRI is performed
Myelogram
x-ray of the spine is completed after dye is injected into the vertebrae
EEG
common procedure for analyzing the electric function of the brain
not exactly an image of the brain; electrodues are placed around the skull and the brain’s electric currents are monitored.
most effective means to detect seizure activity in the brain
