Final Review Flashcards
What is Cushing’s triad and what is it diagnostic of?
Slow heart rate, high blood pressure, and irregular breathing. Diagnostic of high ICP
Why do subregions of the POA differ in size?
They are sexually dimorphic, and they influence reproductive behaviors / reproductive hormones differentially in males and females
What does the VM hypothalamus control, other than feeding?
Subregions will control sexual receptivity and mating behaviors by expressing progesterone receptors. Ablation of these areas will lead to sexual disinterest in both males and females
What relays information about blood volume to the hypothalamus?
NTS (caudal part) and RF (reticular formation), due to baroreceptors in heart and great vessels
What parts of the hypothalamus regulate SANS and PANS?
SANS - middle / posterior part - includes DM / P nuclei extending backwards in the same area
PANS - anterior - PVN
