For each hormone listed below 1 define where it is produced

For each hormone listed below: (1) define where it is produced, (2) what stimulus triggered the production, (3) one target site of action, and (4) the corresponding elicited response. Cholecystokinin (CCK): Thyrotropin-releasing hormone (TRH): Oxytocin: Glucagon: Antidiuretic hormone (ADH):

Solution

Hormone

Site of production

Stimulus

Target

Response

CCK

Duodenum

Acidic contents in stomach/ duodenum

Gall bladder

Contraction, release of bile

TRH

Paraventricular nucleus

Low thyroid hormone level

Pituitary gland

Release of thyroid stimulating hormone

Oxytocin

Supraoptic and Paraventricular nuclei

Stimulation of nipples during breast-feeding

Alveolar myoepithelium

Contraction of alveolar myoepithelium, resulting in let-down of milk

Glucagon

Pancreas

Low blood glucose

Liver

Breakdown of glycogen into glucose

ADH

Posterior pituitary

Low blood pressure

Distal convoluted tubule

Water reabsorption, resulting in renal conservation of water
