List the principle endocrine glands
3. Thyroid gland
4. Parathyroid gland
5. Adrenal gland
What types of hormones does the hypothalamus release?
- Releasing hormones
- Inhibiting hormones
What are the releasing hormones released by the hypothalamus?
- GHRH (growth hormone)
- TRH (thyrotrophin)
- CRH (corticotrophin)
- GnRH (gonadotrophin)
What are the inhibiting hormones released by the hypothalamus?
Hypothalamus usually sends signals to...
Pituitary gland is divided into...
- Anterior Pituitary
- Posterior pituitary
What hormones are released by the a. pituitary?
- GH (growth)
- TSH (thyroid-stimulating)
- ACTH (adrenocorticotrophic)
- LH (luteinizing)
- FSH (Follicle-stimulating)
- PRL (Prolactin.)
What hormones are released by the p. pituitary?
- Antidiuretic hormone (ADH/vasopressin)
Hormones secreted by thyroid gland
Hormones secreted by adrenal cortex
- Mineralocorticoids (aldosterone)
- Glucocorticoids (cortisol)
- Adrenal androgens
Thyroid gland controls...
Hormones secreted by parathyroid gland
PTH (parathyroid hormone)
Parathyroid gland controls...
Ca++ levels in the body
The adrenal gland is divided into
- Adrenal cortex
- Adrenal medulla
Hormones secreted by adrenal medulla
Catecholamines: E and NE
Hormones secreted by ovaries
Hormones secreted by the testes
Hormones secreted by pancreas
- Glucagon (alpha cells)
- Insulin (Beta cells)
- Somatostatin (delta cells)
how are hormones classified?
- Neuroendocrine, NT
What are endocrine hormones?
- sent through blood and carried to target cells
What are paracrine hormones?
- act on nearby cells
Example of paracrine hormone?
Glucagon act on B-cells of the pancreas
Example of endocrine hormone?
ACTH from pituitary act on adrenal cortex
What are autocrine hormones?
- hormone act on cell that secreted it
Example of autocrine hormone
1,25(OH)2vitD from prostate & pancreas
What are NT/NE hormones?
Hormones secreted from neural axon terminals
