Document Summary
Physiology-the strx and fxn of the organs and parts of the body and how they work tgt as a unit to maintain balance. Epithelial - regulate whats carried in and out. Tissue org: endothelial - protection, smooth - expansion / contraction. Not covering in class: integumentary, digestive, repro, immune. Compensatory regulatory mechanism --> w/o it, cells would swell and explode. For example, the steroid hormone cortisol: cytosol and nucleus and cell surface. Lecture: different types of intercellular communication, electrical --- gap jxn, direct communication through gap jxn, direct, bidirectional(not always possible though), very fast (instantaneous, electrically coupled, mvmt of ion across barrier == current. Intravenous anesthetic: propofol, etomidate: flumazenil: binds to same place as bzd (midazolam) and does not activate receptor, location of receptors. Intracellular receptors possible for lipophilic messengers: cell surface receptor req for lipid-insoluble hydrophilic messengers, plasma membrane receptors are transmembrane proteins, channel linked.
