Front 8

Adrenocorticotropic hormone (ACTH): Source and action

Back 8

Front 9

antidiuretic hormone (ADH) (Vasopressin): Source and action

Back 9

Neurosecretory cells in the hypothalamas, secreted by posterior pituitary. Increases the permeability of the distal tube to water and thus allows water reabsorption, increases arterial blood pressure

Front 10

Calcitonin: Source and action

Back 10

parafollicular cells of thyroid. Inhibits osteoclastic bone resorption, which decreases serum Ca

Front 11

Cortico-releasing hormone (CRH): Source, target, and action.

Back 11

produced by neuroendocrine cells of hypothalamus, carried to anterior pitutiarty. Stimulates ACTH release. Also secreted by placenta. Neurotransmitter.

Front 12

Erythropoietin: Source and action.

Back 12

EPO is produced mainly by peritubular fibroblasts of the renal cortex. Regulates red blood cell production.

Front 13

Follicle-stimulating hormone (FSH): Source and action

Back 13

Anterior pituitary. In women, stimulates growth follicles. follicle growth releases inhibin, which shuts off FSH production.
In men, spermatogenesis.

Front 14

Gastrin: Source and action

Back 14

Produced by G cells of the duodenum and in the pyloric antrum of the stomach. Released into blood stream. Stimulates parietal cells of the stomach to secrete hydrochloric acid

Front 15

Glucagon: Source, target and action

Back 15

alpha cells of islets of langerhans. Bind to glucagon receptors causing the liver to release glucose (glycogen)throughglycogenolysis

Front 16

Gonadatropin-releasing hormone (GnRH1):source, target, and action.

Back 16

Synthesized and released by the hypothalamus. Responsible for the release of FSH and LH from the anterior pituitary

Front 17

Growth hormone (GH): Source and action.

Back 17

Anterior pituitary. Stimulates growth and cell reproduction.

Front 18

Inhibin: Source and action.

Back 18

Ovaries or testes. Inhibits FSH production.

Front 19

Insulin: Source and action.

Back 19

Beta cells of the islets of Langerhans. Causes liver and muscle cells to take in glucose and store it in the form of glycogen.

Front 20

Luteinizing hormone (LH): Source and action.

Back 20

Anterior pituitary. Surge triggers ovulation and converts follicle to corpus luteum.

Front 21

Melanocyte-stimulating hormone: Source and action

Back 21

Intermediate pituitary. Skin pigmentation

Front 22

Oxytocin: Source, target and action.

Back 22

Hypothalamus, posterior pituitary. Positive feedback in labor. Breastfeeding.

Front 23

Parathyroid hormone (PTH): Source and action.

Back 23

Parathyroid glands. Acts antagonistically to calcitonin, Increase blood ca2+

Front 24

Prolactin: Source and action

Back 24

Anterior pituitary. Milk production. Represses dopamine.

Front 25

Secretin: Source and action.

Back 25

S cells of the duodenum. Reduces acid secretion from stomach by inhibiting gastrin release from G cells. This helps neutralize the pH of the digestive products entering the duodenum from the stomach.

Front 26

Somatostatin, growth hormone inhibiting hormone (GHIH): Source and action.

Back 26

Hypothalamus. Inhibits release of: GH, TSH, Gastrin, Secretin, Insulin, ang Glucagon. Opposes the effects of Growth Hormone-Releasing Hormone (GHRH)

Front 27

Thrombopoietin: Source and action

Back 27

Produced by liver and kidneys. Stimulates bone marrow cells that produce platelets.

Front 28

Thyroid Stimulating hormone (TSH): Source and action.

Back 28

Anterior Pituitary. Stimulates T3 and T4 secretion. Controlled by TRH.

Front 29

Thyrotropin-releasing hormone (TRH): Source, target and action

Back 29

Hypothalamus. Stimulates the release of TSH and prolactin by the anterior pituitary

Front 30

Front 31

Cortisol: Source and action

Back 31

Adrenal Cortex. It increases blood pressure, blood sugar levels and has immunosuppressive action
