Final Exam Endocrine System Flashcards
6 hormones released by anterior pituitary gland
Thyroid stimulating hormone (TSH)
Adrenocorticotrophic Hormone (ACTH):
Prolactin (PRL)
FSH
LH
Human Growth Hormone (HGH)
What cells local hormones act on
Neighboring cells
- Paracrine - influence nearby cells
- Autocrine - influence the same cell
What do classic/circulating hormones act on?
Distant cells - the hormone is secreted into interstitial fluid and into capillaries
