Q

what are the 4 lobes

A

frontal, parietal, occipital, temporal

20
Q

occipital lobe function

A

visual processsing

21
Q

temperal lobe function

A

auditory procession

22
Q

what is in the corpus callosum

A

myelinated axons

23
Q

what does the corpus callosum do

A

it allows relay between the 2 hemispheres

24
Q

what does grey matter have vs white matter

A

grey has cell bodies
white has myelinated axons

25
Q

what are the two things associated with grey matter that we talked about

A

cerebral cortex
and
basal nuclei

26
Q

cerebral cortex vs basal nuclei

A

cerebral cortex is superficial and conscious
basal nuclei is deep and subsonscious

27
Q

what are the 3 types of fibers in white matter

A

association
commissural
projection

28
Q

association fibers fxn

A

communication w/i a hemisphere

29
Q

commissural fibers fxn

A

communication btw hemispheres

30
Q

projection fibers fxn

A

communication btw cerebrum and other brain parts

31
Q

what is in the diencphalon

A

thalamus and
hypothalamus

32
Q

is the thalamus white or grey matter

A

white

33
Q

thalamus functions

A

relay btwn brain stem and cerebrum
sorts sensroy info

34
Q

hypothalamus functions

A

autonomic fxns like (food intake, water intake, and body temp regulation)
and
Modulates pituitary function

35
Q

what is the pituitary gland

A

the master gland of the endocrine system

36
Q

what does the mid brain do

A

relays info between brain stem and thalamus
coordinates smoothe skeletal muscle activity

37
Q

what is the superior colliculus do

A

visual reflexes

38
Q

what does the infereior colliculus do

A

auditory reflexes

39
Q

what are the superirr and inferior colliculuss apart of

A

the mid brain

40
Q

what are the main parts of the brain stem

A

mid brain , pons, medulla oblongata

41
Q

what is in the metencephalon

A

pons and cerebellum

42
Q

pons function

A

to relay between brain step and cerebellum
to relay between midbrain and medulla oblongata

43
Q

cerebellum function

A

coordination
balance
equilibrium

44
Q

medulla oblongata function

A

relay between spinal cord
decussation
visceral autonomic center

45
Q

what is decussation

A

the crossin gover of axons from right to left sides

46
Q

what is the visceral autonomic center include

A

cardiac center
respitroy center
vasomotor center
