CNS Flashcards
where is diencephalon located?
along ventricles and epithalmus.
Structures deep to Cerebral Hemispheres
Sit on top of the Brain Stem
Surrounding the Third Ventricle
what is the thalamus function?
Thalamus: Sensory Editing Many nuclei (ie Lateral Geniculate Nucleus)
what is the hypothalamus function?
Hypothalamus: Homeostasis, Autonomics,
Biologic clock, Pituitary control
all sensory info is controlled by what? (i.e. smell and taste))
thalamus
breathing is controlling by what?
hypothalamus. (autonomic or unconscious )
diencephalon is composed of what parts?
thalamus (upper diencephalon), hypothalamus (lower diencephalon)
biological clock, sympathetic and parasympathetic controlled by what?
hypothalmus
anything that is alive is going to have what?
a brain stem
pituitary gland is controlled by what?
hypothalmus
Your brain stem keeps you alive. T or F
True
when you are in a coma your brain stem is not working.
T or F
False
brain stem is only involved with turning things on and off. T or F
true
Reflexes register by what part of the brain?
brain stem
constriction and dialation of the pupils are examples of what? and controlled by what part of brain?
reflexes and brain stem.
what is continuous with diencephalon?
mid brain
brain stem is continuous with what?
spinal cord
what innervates brain stem?
CN 3-12
what is known as “the primitive brain”
brain stem
midbrain is composed of what?
colliculi (inferior and superior nuclei)
inferiorcolliculi nuclei control what? superior nuclei control what?
inferior= auditory (analyze where sound is coming from) superior= visual
medulla is continuous with what?
spinal cord
medulla controls what?
Reflexive behaviors (breathing, blinking, coughing, barfing…)….reflexive actions (automatic)
the pons is a part of what structure of the brain?
cerebellum
cerebellum controls what?
motor coordination
what is dysphasia?
cant swallow. something went wrong with brain stem.
when medulla gets squeezed what will happen?
stop breathing
my ability to stay fixed on an object and track it. what part?
brain stem. (mid brain)
motor is output or input of info?
sensory is output or input of info?
motor= output sensory= input
what put you to sleep and wakes you up in the morning is what part of brain system?
reticular system
describe reticular system.
Nuclei throughout Brainstem
Nuclei: Soma embedded in white matter
Projections to all parts of the brain
what happens during a concussion?
Concussion: Stunned RAS (twist in your stem and you lose consciousness at some level =effect brain stem)
if you lose consciousness, what part is effected?
brain stem
axons extending out to different parts of the brain stem send what neurotransmitter to the frontal lobe?
dopamine
taking drugs will effect the what part of the brain by sending dopamine out?
frontal lobe
what part of the brain is known as “the little brain”?
cerebellum
what part of the brain is responsible for balance and coordination of movement?
cerebellum
what does ataxia mean?
uncoordinated movement or movement deficit
“3D center of the universe” what part of the brain
cerebellum
what gets effected by alcohol when you drink?
cerebellum. coordination is off “walk the line” and cant
