Q

hypothalamus- mamillary bodies

A

process olfactory and other sensory info, control reflex eating movements

3
Q

hypothalamus- infundibulum

A

narrow stalk that connects hypothalamus to pituitary gland

4
Q

hypothalamus- tuberal area

A

helps control pituitary gland function

5
Q

function 1-4 of hypothalamus

A
  1. provide subconscious control of skeletal muscle
  2. controls autonomic funct.
  3. coordinates act. of nervous and endocrine sys.
  4. secretes hormones (ADH and oxytocin)
6
Q

funct 5-8 hypothalamus

A
  1. produces emotions and behavioral drives (hungar and thirst)
  2. coordinated vol. and autonomic funct.
  3. reg body temp
  4. control circadian rhythms
7
Q

antidiuretic hormone

A

ADH by supraoptic nucleus

8
Q

oxytocin

A

secreted by paraventricular nucleus

9
Q

preoptic area of hypothalamus

A

reg body temp

10
Q

suprachiasmatic nucleus of hypothalamus

A

contols circadian rhythms

11
Q

limbic sys functions

A

est. emotional states, links conscious funct of cerebral cortex w autonomic funct of brain stem, fascilitates memory storage and retrieval

12
Q

amygdaloid body

A

acts as interface between the limbic sys, cerebrum, and various sensory sys.

13
Q

limbic lobe structures

A

cingulate gyrus, dentate gyrus, parahippocampal gyrus, hippocampus

14
Q

fornix

A

tract of white matter in limbic sys that connects hippocampus with hypothalamus

15
Q

reticular formation

A

part of limbic sys; stim or inhibition affects emotions (rage, fear, pain, sexual arousal, pleasure)

16
Q

central sulcus

A

divides anterior frontal lobe from posterior parietal lobe

17
Q

lateral sulcus

A

divides frontal lobe from temporal lobe

18
Q

parieto-occipital sulcus

A

divides parietal lobe from occipital lobe

19
Q

3 funct principals of the cerebrum

A
  1. Ea hemi receives sensory info from and sends motor commands to the opposite side of body.
  2. The 2 hemis have diff funct, althouh similar structure.
  3. Correspondance between a specific funct and specific region of cerebral cortex is not precise.
20
Q

association fibers

A

connections within one hemi

21
Q

commissural fibers

A

bands of fibers connecting 2 hemi

22
Q

projection fibers

A

connect cerebrum w lower areas

23
Q

arcuate fibers

A

association fibers that are short and connect 1 gyrus to another

24
Q

longitudinal fasciculi

A

association fibers w longer bundles that connect frontal lobe to other lobes in same area

25
Q

commissural fibers-2

A

corpus callosum

anterior commissure

26
Q

internal capsule

A

contains all ascending and descending projection fibers

27
Q

basal nuclei

A

masses of gray matter embedded in the white matter of cerebrum that direct subconscious act.- muscle tone and coordination of learned movement patterns (walking, lifting)

28
Q

precentral gyrus of frontal lobe

A

directs vol. movements

29
Q

primary motor cortex

A

surface of precentral gyrus

30
