external views (dorsal/lateral/ventral) Flashcards
spinal cord (s)
relay info from brain to bod/vice versa
medulla (s,f)
autonomic functions (basic aka breathing/heart rate)
pons (s,f)
autonomic functions (sleep/arousal), connects cerebrum & forebrain
midbrain (s,f)
eye movement, pupil dilation
superior colliculus (s,f)
process visual info (sensory)
inferior colliculus (s,f)
process visual info (motor)
hypothalamus (s,f)
regulate autonomic nervous system, ctrl body temp/thirst/hunger/circadian rhythm, synthesize hormones, fighting/fleeting/fucking (mating)
meninges (f)
protect brain
dura mater (f)
thick/tough (dense/fibrous tissue), outermost layer; provide brain/spinal cord w/extra protective layer, keep CNS stay put by attachment to skull, surrounds/supports blood leaving brain & return to heart
arachnoid mater (f)
loose-fitting sac thin/transparent (stretch like cobweb b/t dura/pia); keep brain in place in skull/shape, also allows blood flow (keep fluids/toxins etc. out of brain)
pia mater (f)
thin, on outer surface of brain (tight membrane); aids in production of CSF, pierced by blood vessels, allow blood flow, enclose CSF
cerebrospinal fluid (f)
cushion brain, circulate nutrients/chemicals
cerebellum (s,f)
coordinate movement, maintain posture, fine motor movement, motor learning, receives some sensory info
cerebellar vermis (s,f)
median portion of cerebellum; proprioception (perception of position/movement of bod)
cerebellar hemisphere (s,f)
2 lateral sides of cerebellum; motor ctrl
cerebrum (s)
rostral to cerebellum
frontal lobe (s,f)
front-est; higher cognition processes, reasoning, personality, attention, memory
parietal lobe (s,f)
behind frontal, on top of occipital; integrate sensory info from bod (somatosensation), process spatial info, temperature perception
occipital lobe (s,f)
hella back under parietal; vision perception
temporal lobe (s,f)
in front of cerebellum, under all the other lobes; hearing, memory
medial longitudinal fissure (s)
deep fissure separating L/R hemispheres of brain
gyri/gyrus (s)
all over cerebrum, surface of brain (bulgy parts)
sulci/sulcus (s)
all over cerebrum, surface of brain (cracks)
grey matter (s)
neuronal cell bodies/unmyelinated axons
white matter (s)
axons encompassed by myelin sheaths (FATTY)
rhinal fissure (s)
extends across; divides pyriform lobe/olfactory bulb
sylvian fissure (s)
divides frontal/temporal lobe; connect to rhinal fissure sorta perpendicular
pyriform lobe (s,f)
process smell
optic chiasm (s)
x thingy
pyramidal tract (s)
b/t pons & medulla
