midbrain PONS; and / medulla CONNECTION TO THE S.C.
cerebral (cortex [gray matter] - outer layer)
thought judgment=Temporal Lobe= Memory Emotion
balance/ good posture/ equilibrium
smooth bodily parts' movements / coordinated mvmt
brainstem = connection "relay" area betw/ S.C. & cerebral hemispheres=Brainstem
relay station CEREBRUM-body/organs-Cerebrum
acts as "transmitter" for sensation
signals for body f.
main regulatory organ of the BODY VITAL SIGNS
works with pituitary gland
brain ventricles (CSF production), 2 cerebral hemispheres w/ corpus callosum + brain stem
/ B works in conj/ w/ endocrine system
receives sensory input:
receives/interprets nerve impulses from tongue/skin/muscles' sensory receptors
skilled motor functions, memory, behavior
Reasoning, forethought (adult brain)
controls hearing & smell - i.e. ears & nose
process new info
Emotions/Memories medial/temporal lobes (teenage brain)
the meninges membrane system = 3 layers P.A.D.
encloses / B & S.C. = Pia mater / Arachnoid membrane / Dura mater CSF
cools & cushions from shock/injury
transports nutrients & chemicals to B & S.C.
conduction pathways to/from / higher/lower CENTERS OF B.
reflexes due to stimuli responses (eyes & head movements)
brainstem: medulla oblongata
- survival f. (hypothalamus = vital signs)
- reflexes vomiting, coughing, sneezing
transmits nerve impulses betw/ B, limbs, lower body
suppresses some stimuli & magnifies others
e.g. pleasant v unpleasant
eg thunder v marching band
hypothalamus' signals re: 6 body VITAL SIGNS
- PITUITARY GLAND / ENDOCRINE ACTIVITY
- body temp
- emotional responses
- hunger sensations
- thirst " "
- circadian rhythm
cranium bones, / Meninges, CSF
inferior to cerebrum;
anterior to cerebellum
starts at cerebellum,
ends at lumbar vertebral reg
