Hypothalamic Nuclei

Question 1

Anterior Nuclei

Answer 1

Decreases body temperature (ants at a hot picnic or turn on the A/C)

Question 2

Posterior Hypothalamic Nuclei

Answer 2

Increases body temperature during hypothermia (freeze my ass (posterior) off)

Question 3

Lateral Hypothalamic Nuclei

Answer 3

Mediates Hunger, stimulated by ghrelin (ghrelin makes you hunghre)

Question 4

Ventromedial Hypothalamic Nuclei

Answer 4

Mediates Satiety, stimulated by leptin which is produced by fat

Question 5

Supraoptic and paraventricular Hypothalamic Nuclei

Answer 5

Synthesizes and secretes ADH and oxytocin

Question 6

Suprachiasmatic

Answer 6

Regulation of circadian rhythm

Question 7

Arcuate

Answer 7

Secretion of dopamine, GH

Question 8

Preoptic nucleus

Answer 8

Thermoregulation, sexual behavior, releases GnRH-producing neurons to migrate from olfactory pit

Question 9

What area of the hypothalamus is involved in kallman syndrome?

Answer 9

Preoptic nucleus, delayed puberty and impaired sense of smell because of failure of GnRH neurons to migrate including failure of neurons to migrate through the cribriform plate.

Question 10

thiamine deficiency affects what part of the limbic system?

Answer 10

Mammillary bodies (associated with memory loss)

Question 11

What part of the limbic system is most susceptible to hypoxia?

Answer 11

The Hippocampus

Question 12

What part of the limbic system is in charge of emotions and decision making?

Answer 12

the amygdala

Question 13

Bilateral damage to the amygdala can cause what syndrome resulting in hyperorality, hypersexuality, and hyperphagia?

Answer 13

Kluver-Bucy syndrome (bilateral destruction of temporal lobes, could be from herpes simplex encephalitis–> can be treated with acyclovir in this case)
