Document Summary
Describe location of endocrine organs, hormones they secrete, and their function. Different types of hormones based on synthesis, secretion, receptor location, and cellular response. Contrast how endocrine and nervous systems communicate. Made of ductless glands scattered throughout body. Glands secrete hormones that travel through blood. Target cells have receptors that bind speci c hormones. Induce adaptive changes to help body cope with stress. What form is it secreted in? (some are secreted in an inactive form and therefore must be activated) Steroids need to be bound to proteins to be transported. Neural input and input from other hormones directly in uence the above. Maintains plasma concentration of hormone at given level (aka. set point)d. Anterior pituitary secretes tsh which activates thyroid causing production of th which inhibits anterior pituitary from secreting tsh. Hydrophilic vs. lipophilic (see 2 images at end of notes) Bind to surface membrane receptors and produce effects through second messenger.
