Flashcards in thalamic and hypothalamic nuclei Deck (12):
1

VentroPosterioMedial Nucleus

thalamic facial sensation and taste

2

VentroPosterioLateral Nucelus

Thalamus - P/T sensation (spinothalamic); Vibration/proprioception (dorsal columns)

3

Lateral Geniculate Nucleus

thalamus - vision

4

Medial Geniculate Nucleus

thalamus - hearing

5

Ventral Lateral Nucleus

thalamus - receives motor input form Basal ganglia

6

Lateral area

hypothalamus - generates hunger

7

Ventromedial area

hypothalamus - generates satiety

8

Anteiror hypothalamus

causes cooling vi parasympathetics

9

Posterior hypothalamus

causes heating via sympathetics

10

Suprachiasmatic nucleus

Hypothalamus - circadian rhythm

11

Arcuate Nucleus

hypothalamus - dopaminergic inhibition of prolactin; GHRH, GnRH

12

Neurohypophysis

posterior pituitary = receives hypothalamic axonal projections from Supraoptic and Paraventricular nuclei to secreted ADH and Oxytocin respectively.
