Endocrine function - regulate cellular & organ function throughout life

- maintain homeostasis

Neurocrine - hormones secreted from nerve terminal

- lack endocrine gland

Paracrine - hormone released by cell acts upon cells nearby

Autocrine - cell releases hormone that acts upon itself

Hypothalamus hormones - releasing & inhibiting hormones

Pituitary hormones - ACTH

- TSH

- GH

- LH

- FSH

- PRL

- SST

Testiuclar hormones - T

- Inhibin

Hormone classes - protein/peptide - largest group - 3-200 amino acids

- steroids & steroid like

- tyrosine-derived hormones

Peptide hormones - mostly made intracellularly

- stored in secretory granules

- Ca2+ induced release

- hydrophillic - usually circulate in free form

- short half life

- bind to membrane receptors

- ANGII extracellularly synthesized from precursors in blood

Steroids & steroid-like hormones - "cholesterol" hormones

- intracellularly synthesized

- not stored in vesicles

- released by diffusion

- hydrophobic - bound to plasma protein in blood leading to longer half-life

- intracellular receptors

Tyrosine-derived hormones - made in adrenal medulla or thyroid

- catecholamines & T3/T
