Document Summary

Opposite to exocrine (secreted outside the body, mammary gland, lumen of gi, etc. ) Acts at a distance from the release site. Autocrine = acts on its own secreting cell (cells can come back to itself) Neuroendocrine = synthesized by nervous tissue and carried in the blood. *neurohormone = released straight form neuron, same chem msgners used in ns and endo system. ** neurohormone if in the ns and hormone if in blood (when hormone release by neuron enters blood) Gland = cluster of cells organized for synthesis/release of compound, can be endo or exocrine. Endocrine is more broad and slow communication compared to ns which is direct, fast and specific. Regulatory chemicals produced in an endocrine gland or scattered cells Secreted into blood and carried to target cell that responds by altering its metabolism. Subjected to tight regulation by feedback from target organs. Regulation of hormones synthesis and mode of action differ greatly based on their structure.
