CENTRAL NERVOUS SYSTEM Flashcards
brain and the spinal cord
THe central nervous system
somatic nervous system and the autonomic nervous system
peripheral nervous system
have numerous receptors that receive messages in the form of chemical impulses from other nerve cells, which are converted into electrical impulses.
Dendrites
transmits these impulses to other neurons.
axon
a small space through which the impulse must pass to get to the next neuron. The space between the axon of one neuron and the dendrite of another
sYNAPTIC CLEF
biochemicals that are released from the axon of one neuron and transmit the Impulse to the dendrite receptors of another neuron
neurotransmitters
lower and more ancient part of the brain essential automatic functions, such as breathing, sleeping, and moving around in a coordinated way
brain stem
more advanced and evolved more recently
forebrain
lowest part of the brain stem, the hindbrain, contains the…
medulla, the pons, and the cerebellum
regulates many automatic activities, such as breathing, the pumping action of the heart(heartbeat), and digestion
HIND BRAIN
motor coordination, and recent research suggests that abnormalities in the cerebellum may be associated with the psychological disorder autism
cerebellum
Also located in the brain stem, coordinates movement with sensory in put and contains parts of the reticular activating system
arousal and tension,
awake or asleep
top of the brain stem
regulating behavior and emotion
thalamus and hypothalamus
relay between the fore brain and the remaining lower areas of the brain stem
thalamus and hypothalamus
base of the forebrain
just above the thalamus and hypothalamus
