BSCI201: Anatomy &Physiology Chapter 4 (Tissues) Notes- Part 1 by Mehrnaz Ighani .Individual body cells are specialized which means each type performs specific functions that maintain homeostasis . Tissues: groups of similar cells that perform common and related function . Histology: study of tissues . 4 basic tissue types: (Fig. 4.1) 1. Connective: supports and binds other tissues together 2. Muscular: movement 3. Nervous: internal communication 4. Epithelial: forms boundaries between different environments . Epithelial tissue: a sheet of cell that covers body surfaces or cavities 2 main types: 1. Covering and lining epithelia: an external/internal surface Ex. Skin 2. Glandular epithelia: secretory tissue in glands Ex. Salivary gland
