Answer 3

Anterior pituitary, stimulates the thyroid to produce thyroid hormones

Question 4

Luteinizing hormone, LH

Answer 4

Anterior pituitary, stimulates ovulation in females, testosterone synthesis in males

Question 5

Follicle-stimulating hormone, FSH

Answer 5

Anterior pituitary, stimulates follicles maturation in females, spermatogenesis in males

Question 6

Oxytocin

Answer 6

Hypothalamus, stored in the posterior pituitary, stimulates uterine contractions during labor and milk secretion during lactation

Question 7

Vasopressin, ADH

Answer 7

Hypothalamus, stored in posterior pituitary, stimulates water reabsorption in kidneys

Question 8

Thyroid hormone

Answer 8

Answer 9

Thyroid, decreases blood calcium level

Question 10

Parathyroid hormone

Answer 10

Parathyroid, increases blood calcium level

Question 11

Glucocorticoids

Answer 11

Adrenal cortex, increase blood glucose level and decreased protein synthesis

Question 12

Mineralocorticoids

Answer 12

Adrenal cortex, increase water reabsorption in the kidneys

Question 13

Epinephrine and norepinephrine

Answer 13

Adrenal Medulla, increase blood glucose level and heart rate

Question 14

Glucagon

Answer 14

Pancreas, stimulates conversion of glycogen to glucose in the liver, increases blood glucose

Question 15

Insulin

Answer 15

Pancreas, lowers blood glucose and increases storage of glycogen

Question 23

Tyrosine derivatives

Answer 23

Thyroid hormones, epinephrine, norepinephrine

Question 24

Aldosterone

Answer 24

Adrenal cortex, Increases sodium and chlorine reabsorption and potassium and hydrogen secretion creating a gain of particles in plasma which eventually increases blood pressure

Question 25

Cortisol

Answer 25

Adrenal cortex, Increases blood glucose by stimulating gluconeogenesis in liver. Degrade adipose tissue to fatty acids for energy
