What is the difference between prolactin and oxytocin? - ✔✔✔
Correct Answer > Prolactin causes lactation of milk
Oxytocin causes ejection of milk
What are the hormones secreted from the anterior pituitary? - ✔✔✔
Correct Answer > TSH - Thyroid Stimulating Hormone
ACTH - Adrenocortical Tropic Hormone
Follicle Stimulating/Luteinizing Hormone
Prolactin Hormone
Growth Hormone
,Describe the hormone pathway that produces T4/T3 - ✔✔✔ Correct
Answer > Thyroid Releasing Hormone (TRH) acts on the Anterior
Pituitary Thyrotopin cells
The Thyrotropin Cells release Thyroid Stimulating Hormone (TSH)
TSH stimulates thyroid to produce T4/T3
Describe the overall hormone pathway that produces corticosteroids -
✔✔✔ Correct Answer > Corticotropin releasing hormone from
hypothalamus acts on corticotropin cells in the anterior pituitary
Anterior pituitary releases Adrenocortical Tropic Hormone which acts
on the cortex of the adrenal medulla
Corticosteroids are produced
Describe the overall hormone pathway that produces spermatogenesis
and oogenesis - ✔✔✔ Correct Answer > Gonadotropin Releasing
Hormone from the hypothalamus acts on the gonadotropic cells of the
anterior pituitary
Anterior pituitary releases Follicle stimulating hormone
,FSH acts on Testes (sertoli cells) to increase spermatogenesis
FSH acts on Ovaries (follicles) to increase oogenesis
Describe the overall hormone pathway that produces androgens,
ovulation, estrogen and progesterone - ✔✔✔ Correct Answer >
Gonadotropin Releasing Hormone from hypothalamus acts on the
anterior pituitary gonadotropic cells
Gonadotropic cells produce luteinizing hormone
LH acts on Testes (Leydig cells) to increase androgenesis
LH acts on Ovaries (Granulosa cells) to increase ovulation and
estrogen/progesterone production
Describe the difference between Trophic and Tropic Hormones
Give examples of each from the anterior pituitary - ✔✔✔ Correct
Answer > Trophic -- target is NON-Endocrine glands
--Growth Hormone
--Prolactin
, Tropic -- target is Endocrine glands
--TSH
--ACTH
--FSH
--LH
Describe the overall hormone pathway of growth hormone - ✔✔✔
Correct Answer > Hypothalamus produces growth hormone releasing
hormone which acts on the adenohypophysis
Growth Hormone is released by the anterior pituitary
Growth hormone triggers the liver to release insulin like growth factor
(somatomedin) -- primary growth mediator for different tissues
through paracrine/autocrine/endocrine actions
Growth hormone also acts directly on muscle tissues, bone tissues,
nerve tissues, and other tissues to stimulate growth
Describe the overall hormone pathway of prolactin and its effects -
✔✔✔ Correct Answer > Pregnancy/baby suckling influences
hypothalamus to produce prolactin releasing hormone
PRH acts on the anterior pituitary to produce prolactin
