Nb2 - Hypothalamus And Pituitary Gland

Front 1

Medial preoptic nucleus (3)

Back 1

Releases gonadotropin releasing hormone
(GnRH) --> gonadotropes of adenohypophysis (anterior pituitary)

Neurons sense BODY TEMPERATURE

Receives input about WATER BALANCE

Front 2

Supraoptic nucleus - 2 hormones

Back 2

Neurons produce vasopressin (ADH) & oxytocin

Front 3

Paraventricular nucleus - 4 hormones

Back 3

Neurons produce oxytocin, ADH, growth hormone inhibiting hormone (GIH), and corticotrophin releasing hormone (CRH)

Front 4

Anterior nucleus

Back 4

Defensive, reproductive and feeding behaviors, and
autonomic functions; provides inputs to other
hypothalamic nuclei and limbic areas involved in these functions

Front 5

Suprachiasmatic nucleus

Back 5

master clock for CIRCADIAN RHYTHMS; receives input from retina

Front 6

Dorsomedial nucleus - 1 hormone

Back 6

– produces thyrotropin releasing hormone (TRH)for anterior pituitary

Front 7

Ventromedial Nucleus (2)

Back 7

SATIETY CENTER; has receptors for ghrelin and leptin

Front 8

Arcuate Nucleus - 3

Back 8

produce releasing and inhibiting hormones for anterior
pituitary hormones: GnRH & Growth Hormone Releasing factor (GHRH); Prolactin Inhibiting Hormone (PIH; a.k.a. Dopamine)

Front 9

Mammillary bodies

Back 9

RECENT MEMORY; connects with hippocampus
via fornix

Front 10

Posterior nucleus

Back 10

continuous with periaqueductal gray matter of midbrain; promotes HEAT CONSERVATION & HEAT GAIN

Front 11

Lateral preoptic nucleus

Back 11

Neurons sense BODY TEMPERATURE

Front 12

Lateral nucleus (Anterior Lateral area)

Back 12

contains MFB

Front 13

Lateral nucleus (Tuberal lateral area)

Back 13

FEEDING CENTER; contains MFB

Front 14

Lateral nucleus (Posterior lateral area)

Back 14

histaminergic fibers --> cerebral cortex, thalamus
(participate in SLEEP/WAKE CYCLE); contains MFB
