MOA: Pituitary and Thyroid Hormones

Question 1

Stimulates release of adrenocorticosteroids and adrenal androgens.

At the adrenal gland, converts cholesterol to cortisol

Answer 1

ACTH (adrenocorticotropic hormone)

Question 2

Stimulates cell proliferation, bone growth, and cartilage synthesis

Answer 2

GH (growth hormone)

Question 3

Regulates gonadal steroid hormone

Answer 3

LH and FSH

Question 4

Stimulates and maintains lactation
Inhibited by dopamine

Answer 4

Prolactin

Question 5

Stimulates uptake of iodine and synthesis of T3 and T4 (thyroid hormones)

Answer 5

TSH (Thyroid-stimulating hormone)

Question 6

Stimulates the release of growth hormone

Answer 6

GHRH (Growth hormone releasing hormone)

Question 7

Suppresses release of GH and TSH

Answer 7

GHIH (Growth hormone inhibiting hormone)

Question 8

Stimulates the release of FSH and LH

Answer 8

GNRH (Gonadotropin releasing hormone)

Question 9

Stimulates the release of TSH

Answer 9

TRH (Thyrotropin releasing hromone)

Question 10

Stimulates uterine contraction and milk ejection
Used clinically to induce labor (Pitocin)

Answer 10

Oxytocin

Question 11

Stimulates increased water permeability and reabsorption in the kidney.
Also causes constriction of vascular smooth muscle

Answer 11

Vasopressin/ ADH

Question 12

Can be used to destroy part of the thyroid
Pharmacologic dose of inhibits production of thyroid hormone

Answer 12

Iodine and potassium iodine

Question 13

active version of thyroid hormone

Answer 13

Liothyronine (synthetic T3)

Question 14

inactive version of thyroid hormone

Answer 14

Levothyroxine (T4)

Question 15

Drug used to inhibit a step in production of thyroid hormone.
Inhibits T3/T4 production

Answer 15

Methimazole and Propylthiouracil

Question 16

Answer 16

ACTH (adrenocorticotropic hormone)
GH (Growth hormone)
LH (Luteinizing hormone)
FSH (follicle stimulating hormone)
Prolactin
THS (Thyroid stimulating hormone)

Question 17

Hypothalamus Hormones (5)

Answer 17

1)GHRH (Growth hormone releasing hormone)
2)Somatostatin/GHIH (Growth hormone inhibiting hormone)
3) Gonadorelin/GnRH (Gonadotropin releasing hormone)
4) CRH (Corticotropin releasing hormone)
5) TRH (Thyrotropin releasing hormone)

Question 18

Posterior Pituitary hormones (2)

Answer 18

Oxytocin (pitocin)
Vasopressin/ ADH

Drugs that affect the thyroid (5)

Answer 19

1) Iodine and potassium iodide
2) Liothyronine
3) Levothyroxine (Synthroid)
4) Methimazole
5) Propylthiouracil
