Lab 5 - Endocrinology Flashcards
where are the thyroid glands
lobes on either side of the trachea
what is the function of the thyroid glands
increase basal metabolic rate
by increasing BMR, what do the thyroid glands increase
heart rate
cardiac output
vasodilation
O2 and energy consumption
thermogenesis
sensitivity to adrenergic receptors
what are hypothalamic nuclei
neurons involved in specific center organized in functional clusters
what are hypothalamic nuclei organized in
functional clusters
what are the 3 regions for hypothalamic nuclei
anterior
medial/tuberal
posterior
what is the anterior hypothalamic nuclei region responsible for
circadian rhythm
thermoregulation
what is the medial/tuberal hypothalamic nuclei region responsible for
eating habits
satiety
regulation of BP and HR
what is the posterior hypothalamic nuclei region responsible for
memory
energy balance
shivering
sleep
learning
what happens when you treat with a hormone
you activate all levels below that hormone, all the way to the biological actions
you inhibit all levels above that hormone, including the producing gland, by means of negative feedback
