Endocrinology Flashcards
cell-cell communication: signals targeting its own self
Autocrine Signaling
cell-cell communication: via blood vessel targeting distant cells
Endocrine Signaling
cell-cell communication: signals targeting adjacent cell
Paracrine Signaling
makes, produces, and secretes, substances used by body/ given off from it
Glands
secreted via ducts into body surface
Exocrine
ductless, thru directly into blood or lymph
Endocrine
chemical messengers
bridge of chemical communication between 2 cells to initiate effect
Hormones
Each hormone acts at a specific site to induce certain characteristic biochemical changes, what are the factors to consider for a certain target cell to be activated
- hormone binding
- blood levels of hormones
- number of receptors of target cell
- strength of binding
Four primary arenas of hormone action
- reproduction
- growth & development
- maintenance of internal environment
- energy production, utilization & storage
