Flashcards in chapter 14 test part 2 Deck (60):
1

hypothalamus- mamillary bodies

process olfactory and other sensory info, control reflex eating movements

2

hypothalamus- mamillary bodies

process olfactory and other sensory info, control reflex eating movements

3

hypothalamus- infundibulum

narrow stalk that connects hypothalamus to pituitary gland

4

hypothalamus- tuberal area

helps control pituitary gland function

5

function 1-4 of hypothalamus

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

funct 5-8 hypothalamus

5. produces emotions and behavioral drives (hungar and thirst)
6. coordinated vol. and autonomic funct.
7. reg body temp
8. control circadian rhythms

7

antidiuretic hormone

ADH by supraoptic nucleus

8

oxytocin

secreted by paraventricular nucleus

9

preoptic area of hypothalamus

reg body temp

10

suprachiasmatic nucleus of hypothalamus

contols circadian rhythms

11

limbic sys functions

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

12

amygdaloid body

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

13

limbic lobe structures

cingulate gyrus, dentate gyrus, parahippocampal gyrus, hippocampus

14

fornix

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

15

reticular formation

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

16

central sulcus

divides anterior frontal lobe from posterior parietal lobe

17

lateral sulcus

divides frontal lobe from temporal lobe

18

parieto-occipital sulcus

divides parietal lobe from occipital lobe

19

3 funct principals of the cerebrum

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

association fibers

connections within one hemi

21

commissural fibers

bands of fibers connecting 2 hemi

22

projection fibers

connect cerebrum w lower areas

23

arcuate fibers

association fibers that are short and connect 1 gyrus to another

24

longitudinal fasciculi

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

25

commissural fibers-2

corpus callosum
anterior commissure

26

internal capsule

contains all ascending and descending projection fibers

27

basal nuclei

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

precentral gyrus of frontal lobe

directs vol. movements

29

primary motor cortex

surface of precentral gyrus

30

pyrimidal cells

neurons of the primary motor cortex

31

sensory areas of cortex

postcentral gyrus of parietal lobe (somatic sensory info-touch, pressure, pain, vibration, taste, and temp) and primary sensory cortex

32

hypothalamus- infundibulum

narrow stalk that connects hypothalamus to pituitary gland
