Ch 18 Hormones

Question 1

adrenaline

epinephrine

Answer 1

secreted by the adrenal medulla; increases heart rate and blood pressure

Question 2

adrenocorticotropic hormone (ACTH)

Answer 2

secreted by the anterior lobe of the pituitary gland (adenohypophysis); also called adrenocorticotropin.
ACTH stimulates the adrenal cortex

Question 3

aldosterone

Answer 3

secreted by the adrenal cortex; increases salt (sodium) reabsorption

Question 4

androgen

Answer 4

male hormone secreted by the testes and to a lesser extent by the adrenal cortex; testosterone is an example

Question 5

antidiuretic hormone (ADH)

Answer 5

secreted by the posterior lobe of the pituitary gland (neurohypophysis). ADH (vasopressin) increases reabsorption of water by the kidney

Question 6

calcitonin

Answer 6

secreted by the thyroid gland; increases blood calcium levels

Question 7

cortisol

Answer 7

secreted by the adrenal cortex; increases blood sugar. It is secreted in times of stress and has an anti-inflammatory effect

Question 8

epinephrine (adrenaline)

Answer 8

secreted by the adrenal medulla; increases heart rate and blood pressure and dilates airways (sympathomimetic). It is part of the bodies fight of flight reaction

Question 9

estradiol

Answer 9

estrogen (female hormone) secreted by the ovaries

Question 10

estrogen

Answer 10

female hormone secreted by the ovaries and to a lesser extent by the adrenal cortex. Examples are estradiol and estrone.

Question 11

follicle-stimulating hormone (FSH)

Answer 11

secreted by the anterior lobe of the pituitary gland (adenohypophysis). FSH stimulates hormone secretion and egg production by the ovaries and sperm production by the testes

Question 12

glucagon

Answer 12

secreted by the alpha islet cells of the pancreas; increases blood sugar by conversion of glycogen (starch) to glucose

Question 13

growth hormone (GH);
somatotropin

Answer 13

secreted by the anterior lobe of the pituitary gland; (adenohypophysis); stimulates growth of bones and soft tissues

Question 14

insulin

Answer 14

secreted by the beta islet cells of the pancreas. Insulin helps glucose (sugar) to pass into cells, and it promotes the conversion of glucose to glycogen

Question 15

luteinizing hormone (LH)

Answer 15

secreted by the anterior lobe of the pituitary gland (adenohypophysis); stimulates ovulation in females and testosterone secretion in males

Question 16

norepinephrine

Answer 16

secreted by the adrenal medulla; increases heart rate and blood pressure (sympathomimetic). Nor- in chemistry means a parent compound from which another is derived. Also called noradrenaline

Question 17

oxytocin (OT)

Answer 17

secreted by the posterior lobe of the pituitary gland (neurohypophysis); stimulates contraction of the uterus during labor and childbirth

Question 18

parathormone (PTH)

Answer 18

secreted by the parathyroid glands; increases blood calcium

Question 19

progesterone

Answer 19

secreted by the ovaries; prepares
