DAT HORMONES QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
ADH (antidiuretic hormone)/ vasopressin - ANSWER Source: Posterior pituitary (does not synthesize
hormones, it stores ADH produced by the hypothalamus)
Target: Kidney
Action: Increases reabsorption of water
-Increases reabsorption of water by increasing the permeability of nephron's collecting duct.
Oxytocin - ANSWER Source: Posterior pituitary(does not synthesize hormones, it stores oxytocin
produced by the hypothalamus)
Target: Mammary glands
Action: milk letdown
-Secreted during childbirth. Increases strength of uterine contractions and stimulates milk ejection
TSH (Thyroid stimulating hormone) - ANSWER Source: Anterior pituitary (tropic hormones-stimulate
other endocrine glands)
Target: Thyroid
Action: Secretion of T3 and T4
-stimulates thyroid gland to release thyroid hormones
ACTH (adrenocorticotropic hormones) - ANSWER Source: Anterior pituitary (tropic hormones-stimulate
other endocrine glands)
Target: Adrenal cortex
Action: secretion of glucocorticoids
-Involved in regulation of metabolism of glucose
FSH (follicle stimulating hormones) - ANSWER Source: anterior pituitary (tropic hormones-stimulate
other endocrine glands)
Target: Ovaries, testes
Action: Regulates oogenesis and spermatogenesis
, -Females: stimulates maturation of ovarian follicles to secrete estrogen.
-Males: stimulates maturation of seminiferous tubules and sperm production
LH (luteinizing hormone) - ANSWER Source: anterior pituitary (tropic hormones-stimulate other
endocrine glands)
Target: Ovaries, testes
Action: Regulates oogenesis and spermatogenesis
-Females: stimulates formation of the corpus lute
-Males: stimulates interstitial cells of the testes to produce testosterone
PRL (prolactin) - ANSWER Source: Anterior pituitary (hormones-directly stimulate target organs)
Target: mammary glands
Action: production of milk
Endorphins - ANSWER inhibit perception of pain; technically a neurohormone
GH (Growth hormones) aka somatotropin - ANSWER Source: Anterior pituitary (hormones-directly
stimulate target organs)
Target: Bone, muscle
Action: Stimulates growth
Glucagon - ANSWER Source: Pancreas (alpha cells)
Target: Liver
Action: Increase blood glucose
Insulin - ANSWER Source: Pancreas (beta cells)
Target: Liver, muscles, fats
Action: Decreases blood glucose
