Definition

brainstem

midbrain PONS; and / medulla CONNECTION TO THE S.C.

cerebrum; cerebral hemispheres cerebral (cortex [gray matter] - outer layer)

thought judgment=Temporal Lobe= Memory Emotion

cerebellum

balance/ good posture/ equilibrium

smooth bodily parts' movements / coordinated mvmt

thalamus
brainstem = connection "relay" area betw/ S.C. & cerebral hemispheres=Brainstem

relay station CEREBRUM-body/organs-Cerebrum

acts as "transmitter" for sensation

hypothalamus

  1. signals for body f.

  2. main regulatory organ of the BODY VITAL SIGNS

  3. works with pituitary gland

brain ventricles (CSF production), 2 cerebral hemispheres w/ corpus callosum + brain stem

/ B works in conj/ w/ endocrine system

occipital lobe

eyesight

parietal lobe

receives sensory input: receives/interprets nerve impulses from tongue/skin/muscles' sensory receptors

frontal lobe

skilled motor functions, memory, behavior Reasoning, forethought (adult brain)

temporal lobe

controls hearing & smell - i.e. ears & nose process new info judgment some speech 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

CSF or spinal fluid

  1. cools & cushions from shock/injury

  2. transports nutrients & chemicals to B & S.C.

brainstem: MIDBRAIN pons

  1. conduction pathways to/from / higher/lower CENTERS OF B.

  2. reflexes due to stimuli responses (eyes & head movements)

brainstem: medulla oblongata

  1. survival f. (hypothalamus = vital signs) AND
  2. reflexes vomiting, coughing, sneezing

S.C. spinal cord MYEL/O

transmits nerve impulses betw/ B, limbs, lower body

thalamus

suppresses some stimuli & magnifies others e.g. pleasant v unpleasant eg thunder v marching band

hypothalamus' signals re: 6 body VITAL SIGNS

  1. PITUITARY GLAND / ENDOCRINE ACTIVITY
  2. body temp
  3. emotional responses
  4. hunger sensations
  5. thirst " "
  6. circadian rhythm

BRAIN Protection

cranium bones, / Meninges, CSF

Brainstem

inferior to cerebrum; anterior to cerebellum

Spinal Cord S.C.

starts at cerebellum, ends at lumbar vertebral reg
