Answer 8

thalamus

Question 9

part of thalamus associated with motivated behavior, affect, emotion

Answer 9

limbic system (anterior division)

Question 10

largest thalamic nucleus and does integration of sensory information and is also involved with limbic system

body

Question 14

medial geniculate is blank

Answer 14

auditory

Question 15

lateral geniculate is blank

Answer 15

visual

Question 16

lesion to thalamus causes a blank loss of function

Answer 16

contralateral

Question 17

pain and temp crosses over blank

Answer 17

immediately

Question 18

touch crosses over blank

Answer 18

higher up than pain and temp but still below thalamus

Question 19

nuclei that gets input from reticular formation and is throughout the brain cortex for consciousness

Answer 19

intralaminar nuclei

Question 20

nuclei that functions to modulate thalamic activity, and has input from cerebral cortex

Answer 20

reticular nucleus

Question 21

this becomes infundibular stalk

Answer 21

median eminence

Question 22

gray matter between mammillary bodies and infundibular stalk, tuberomammillary tract, has histamine and regulates circadian rythms

Answer 22

tuber cinerum

know thalamic nuclei not hypothalamic

Answer 23

ok

Question 24

these nuclei of hypothalamus control posterior lobe of the pituitary (neurohypophysis)

paraventricular, supraoptic

Question 25

posterior pituitary releases these
