NUR 305: Endocrine – Questions & Verified SolutionsHormones that act on neighboring cells Correct Ans - paracrine
Hormones that act on the same cell that secreted them Correct Ans -
autocrine
Transported through protein carriers (requires a vesicle Correct Ans -
bound hormone
Needs to be free to send message to the target tissue (no vesicle)
Correct Ans - free hormone
Due to autoimmunity, infection, inflammation, infarction, or TUMOR
Correct Ans - deficient hormone
Due to TUMORS, autoimmunity, or genetic mutation Correct Ans -
excess hormone
Causing dysfunctional receptor sites Correct Ans - hormone
resistance
Primary: at the site of the gland
secondary: pituitary
tertiary: hypothalamus Correct Ans - hypothalamus-pituitary-
hormone axis
increased amount of hormone causes inhibition of release Correct Ans
- negative feedback system
increased amount of hormone causes more to be released (oxytocin in
labor) Correct Ans - positive feedback system
prolonged, excessive stimulation of endocrine system leads to decrease in
number of receptor sites and receptor insensitivity - hormone cannot cause
desired effects Correct Ans - down regulation
stores and secretes hormones Correct Ans - pituitary gland
, hypothalamic hormones regulate the synthesis and secretion of pituitary
gland hormones Correct Ans - hypothalamus
growth hormone (GH), Thyroid stimulating hormone (TSH),
Adrenocorticotropic hormone (ACTH), Follicle stimulating hormone (FSH),
Luteinizing hormone (LH), Prolactin, and Melanocyte-Stimulating Hormone
(MSH) Correct Ans - anterior pituitary hormones
Antidiuretic hormone (ADH) and oxytocin Correct Ans - Posterior
Pituitary hormones
decreased secretion of anterior pituitary gland Correct Ans -
hypopituitarism
congenital, destruction of anterior pituitary, deficiency of hypothalamic
hormones (due to stress, change in body weight, anorexia, bulimia, and
heart failure) Correct Ans - causes of hypopituitarism
growth defects in children, amenorrhea, erectile dysfunction, postural
hypotension Correct Ans - clinical manifestations of
hypopituitarism
over secretion of anterior pituitary gland Correct Ans -
hyperpituitarism
pituirary adenomas (non-cancerous tumor), and hypothalamic lesions
Correct Ans - causes of hyperpituitarism
depends on hormone affected
EX: amenorrhea, galactorrhea, visual disturbances, headache, and
acromegaly (increased GH) Correct Ans - clinical manifestations of
hyperpituitarism
synthesized by hypothalamus and stored in posterior pituitary, maintains
body's fluid balance through reabsorption of water by the kidney's
- anti-urinate Correct Ans - antidiuretic hormone (vasopressin)
decreased ADH secretion or renal response to ADH resulting in excess
water loss
