26 Flashcards
Syndrome
a type of hypogonadotropic hypogonadism that is associated with anosmia
olfactory bulb does not develop normally and hypothalamus fails to regulate FSH and LH releasae
Kallman syndrome
syndrome characterized by obesity and gonadal undevelopment related to a pituitary tumor
Froehlich Syndrome
usual causes are: craniopharyngioma, glioma
syndrome characterized by truncal obesity with reddish purple cutaneous striae over the abdomen and other parts, dryness and pigmentation of the skin and fragility of skin vessels
Cushings Disease/syndrome
When adrenal insufficiency is secondary to disease in the pituitary, ACTH is expectedly to be
a. low/absent
b. normal
c. high
and cortisol secretion is ____
aldosterone _____
- low/absent - ACTH
- cortisol is markedly reduced
- aldosterone - normal
appetite center in the hypothalamus
ventrolateral nucleus
satiety center in the hypothalamus
ventromedial nucleus
leading cause of precocious puberty in both boys and girls
hamartoma of the hypothalamus
page 589
state fo excessively dilute urine that results from loss of antidiuretic hormone/vasopressin
Diabetes Insipidus
hormone secreted by the pineal gland
melatonin
main cellular element of the pineal gland
pinealocyte
cells in these nuclei of the hypothalamus responsible for secreting the following oligopeptides: vasopressin and oxytocin
supraoptic and paraventricular nuclei
hormone responsible for inhibiting the release of GH
somatostatin, GHrelease -inhibiting hormone
peptide synthesized in the liver that exerts feedback control of GH by inhibiting the pituitary somatotropes and stimulating the release of somatostatin
somatomedin C
nuclei found in the anterior group of neurons in the hypothalamus
anterior group
supraoptic
preoptic
paraventricular
nuclei found in the middle group of neurons in the hypothalamus
middle group
tuberal
arcuate
ventromedial
dorsomedial
nuclei found in the posterior group of neurons in the hypothalamus
posterior
mammillary
posterior hypothalamic nuclei
2 main efferent fiber systems in the hypothalamus
mammillothalamic tract
mammillotegmental tract
inferior surface fo the hypothalamus which bulges downward from the floor of the 3rd ventricle and gives rise to the infundibulum
tuber cinereum
T/F pineal tumors do not secrete melatonin
true
oligopeptide that is hypothesized to be the cause of hyponatremia in cerebral salt wasting (Nelson Syndrome)
Atrial Natriuretic Factor
