Hormones Flashcards
Gastrin
Stimulates the secretion of HCl
Gastric Inhibitory Peptide
- Stimulates the release of insulin
- Inhibits HCl
Pepsinogen
-Becomes pepsin which digests protein
CCK
- Slows gastric mobility
- Stimulates release of bile from the gallbladder
- Stimulates the secretion of pancreatic enzymes
Secretin
-Stimulates bicarb secretion from the pancreas to increase neutralize acid chyme
Glucagon
- Secreted by alpha cells
- Stimulate liver output of glucose by converting glycogen to glucose and forming glucose from amino acids
- Stimulates the breakdown of fat for energy
- Opposite of insulin
Insulin
- Made by beta cells
- Stimulates cell uptake of glucose
- Lowers blood glucose levels
Somatostatin
- Inhibits glucagon and insulin secretion
- Slows peristalsis of the GI and biliary system
Pancreatic polypeptide
- Secreted via PP cells
- Acts on the stomach to stimulate the secretion of gastric enzymes and the SI to inhibit mobility
T3 and T4
-Control the metabolic rate
Corticosteroids
-Glucose metabolism, salt and water metabolism
Estrogen
- Endometrium proliferative development
- ovum formation
Progesterone
- Endometrium secretory development
- Ovum formation
Testosterone
-Sperm development
Growth hormone/ somatotropin
-Bone and soft tissue growth
Prolactin
-Breast milk formation
ADH (posterior pit)
Renal water retention
Oxytocin (posterior pit)
- Uterine muscle contraction
- Breast duct contraction
- Milk ejection
FSH
-Stimulate ovulation and sperm formation
LH
- Form corpus luteum and secrete progesterone and estrogen
- Secrete testosterone
MSH (melanocyte stimulating hormone)
-Increases melanin production
