endocrine system anatomy

Question 1

neurohypophysis

Answer 1

neuron system extending from hypothalamus to post pit

Question 2

adenohypophysis

Answer 2

anterior pituitary connected to hypothalamus through capillary plexuses

Question 3

hypothalamo- hypohyseal portal system

Answer 3

the connection between hypothalamus and anterior pituitary, transports regulatory hormones

Question 4

hypothalamo- hypohyseal tract

Answer 4

pathway between hypothalamus and post pit

Question 5

releasing vs inhibiting hormones

Answer 5

both are released from ant pit
releasing: causes an increase in secretion of a specific ant pit hormone
inhibiting: causes a decrease in secretion of a specific ant pit hormone

Question 6

thyroid stimulating hormone

Answer 6

released by Ant Pit, acts on thyroid, stimulates hormone release

Question 7

Prolactin

Answer 7

released by Ant Pit, regulates breast milk production in females

Question 8

adrenocorticotropic hormone (ACTH)

Answer 8

released by Ant Pit, stimulates adrenal cortex to secrete glucocorticoids, increases blood nutrient levels

Question 9

follicle stimulating and luteinizing hormone (FSH and LH)

Answer 9

released by Ant Pit, act on gonads, development of egg and sperm cells, release of reproductive hormones

Question 10

growth hormone

Answer 10

released by Ant Pit, stimulates liver to release insulin like growth factors which stimulate cell growth and division, regulates growth/metabolism, tissue maintenance

Question 11

ADH

Answer 11

released by post pit and produced in hypothalamus, targets the kidney, conserves body water by reducing urine, promotes water reabsorption into circulation

Question 12

Oxytocin

Answer 12

released by post pit and produced in hypothalamus, targets smooth muscle of uterus and breasts, causes contractions and ejection of breast milk
