Endocrine System (K)
The endocrine system from Quick sheets
Hormone | Source | Action |
---|---|---|
Luteinizing (LH) | Anterior Pituitary | Stimulates ovulation; testosterone synthesis |
Adrenocorticotropic (ACTH) | Anterior Pituitary | Stimulates adrenal cortext to make and secrete gluticocorticoids |
Thyroid Stimulating (TSH) | Anterior Pituitary | Stimulates the thyroid to produce thyroid hormones |
Prolactin | Anterior Pituitary | Stimulates Milk Production and Secretion |
Endorphins | Anterior Pituitary | Inhibit perception of pain in the brain |
Growth Hormone | Anterior Pituitary | Stimulates bone and muscle growth/lipolysis |
Oxytocin | Hypothalamus; stored in posterior pituitary | Stimulates uterine contractions during labor, milk secretion during lactation |
Vasopressin (ADH) | Hypothalamus; stored in posterior pituitary | Stimulates water reabsorption in kidneys |
Thyroid hormones (T3, T4) | Thyroid | Stimulates metabolic activity |
Calcitonin | Thyroid | Decreases (tones down) blood calcium level |
Parathyroid hormone | Parathyroid | Increases blood calcium level |
Glucocorticoids | Adrenal cortex | Increases blood glucose level and decreases protein sythesis |
Mineralcorticoids | Adrenal cortex | Increases water reabsorbtion in kidneys |
Epinephrine | Adrenal medulla | Increases blood glucose level and heart rate |
Glucagon | Pancreas | Stimulates conversion of glycogen to glucose in the liver, increases blood glucose |
Insulin | Pancreas | Lowers blood glucose, increases glycogen stores |
Somatostatin | Pancreas | Supresses secretion of glucagon and insulin |
Testosterone | Testes | Maintains male secondary sexual characteristics |
Estrogen | Ovary/Placenta | Maintains female secondary sexual characteristics |
Progesterone | Ovary/Placenta | Promotes growth/maintenance of endometrium |
Melatonin | Pineal | Unclear in humans |
Atrial natriuretic peptide | Heart | Involved in osmoregulation and vasodilation |
Thymosin | Thymus | Stimulates T lymphocyte development |
Norepinephrine | Adrenal Medula | Increases blood glucose level and heart rate |
Follicle-stimulating (FSH) | Anterior Pituitary | Stimulates follicle maturation; spermatogenesis |
