Document Summary

Lecture 3 - tissue level of organization and homeostasis. Tissue: a group of cells from a site in an embryo and function together to carry out specialized activities. Tight junction: sealing transmembrane protein strands hold adjacent plasma membrane together. Adherens junction: an anchoring junction; forms adhesion belts, which encircle cells and are joined by transmembrane proteins. Hemidesmosome: anchors to basement membrane (i. e. airway epithelial cells) Gap junction: forms intercellular passageway b/w membranes of adjoining cells, facilitates the movement of small molecules. Epithelial: covering and lining of epithelium & glandular epithelium. I. e. internal blood vessel wall, skin, heart chamber walls, gi tract, liver, pancreas, salivary glands, thyroid. ___blast: generates matrix (inc. fibers and ground substances) No striations, uninucleate (one nucleus), spindle-shaped, lines walls of hollow organs (i. e. stomach, blood vessels) Striations, uninucleate, branching, interdigitate at intercalated discs, propel blood into circulation. Striations, multinucleate, cylindrical, attached to bone or skin. Excitable, generate & conduct nerve impulses, regulate & control body.
