Limbic/Hypothalamus

Question 1

this helps with basic instincts like survival, reproduction, avoidance, pleasure, memory, satisfaction

Answer 1

limbic system

Question 2

limbic system is closely associated with this sense

Answer 2

olfactory (neurons replaced every 1-2 months)

Question 3

olfactory bulb is composed of these types of neurons

Answer 3

secondary mitral cells; olfactory TRACT is composed of their axons

Question 4

final destinations of olfactory info

Answer 4

pyriform cortex and amygdala, which is part of the limbic system (without passing through thalamus*)

Question 5

olfactory info going to the amygdala must go through

Answer 5

lateral olfactory stria

Question 6

olfactory info going to the septal nucleus must go through

Answer 6

medial olfactory stria

Question 7

limbic lobe is comprised of

Answer 7

amygdala, septal area, cingulate gyrus, hippocampus

Question 8

in a coronal section, the septal area is at the junction of

Answer 8

anterior commissure and the fornix

Question 9

2 tracts that the septal area communicates with the amygdala through

Answer 9

stria terminalis

diagonal band of Broca

Question 10

describe the Papez circuit pathway; what does it link?

Answer 10

hippocampus, fornix, mammillary bodies, mammillothalamic tract, ant. nuc. of thalamus, cingular gyrus, parahippocampal gyrus, hippocampus

limbic system and the cortex

Question 11

serves as anatomic substrate for emotional experiences and convergence of cognitive activities with emotional experience and expression

Answer 11

Papez circuit

Question 12

area of limbic system that does reward and pleasure

Answer 12

septal area

Question 13

the pathway that links septal area to reproduction

Answer 13

septal area through the stria medularis thalami to the habenular nuclei which goes to reproduction

Question 14

stria medularis thalami connects septal area to..

stria terminalis connects septal area to..

Answer 14

1. habenular nuclei (reproduction)

2. amygdala

Question 15

part of limbic system responsible for subjective feeling/memory, emotion, like/dislike

part of limbic system responsible for new memory, short term memory, learning

Answer 15

1. amygdala

2. hippocampus

Question 16

first area of limbic system affected by Alzheimer’s disease

Answer 16

hippocampus (new memory)

Question 17

side effects of frontal lobotomy

Answer 17

trouble concentrating, easily distracted, inappropriate behaviors, apparent lowering of moral standards

Question 18

limbic system is responsible for these 5 F’s

Answer 18

feeding

fleeing

fighting

feeling

fucking

Question 19

effects of the limbic system/hypothalamus innervating autonomics and endocrine glands

Answer 19

heart pounding

sweating

needing to go to bathroom again?..

Question 20

the hypothalamus is connected to this gland; how do they communicate/release hormones?

Answer 20

hypophysis (pituitary gland)

hypothalamus sends hormones to anterior pituitary b hypophysial portal system

Question 21

hormones released by hypothalamus, and what tracts they each travel with

Answer 21

corticotropin releasing hormone via hypophysial portal system

oxytocin and ADH (to post pituitary) via hypothalamo-hypophysial tract

Question 22

damage to this area can cause diabetes insipidus

Answer 22

supraoptic nucleus, paraventricular nucleus (no release of ADH)

Question 23

damage to this area could cause obesity

Answer 23

bilateral medial hypothalamic nucleus (no satiety)

Question 24

damage to this area could cause hyperthermia

Answer 24

anterior hypothalamus (heat conservation center becomes dominant)

Question 25

hypothalamus wears TAN HATS to bed

Answer 25

``` thirst adenohypophysis neurohypophysis (post pituitary) hunger autonomic temperature sexual urges circadian rhythm ```
