Document Summary
Four broad categories of tissue: epithelial tissue, connective tissue, nervous tissue, muscular tisse. Structure with discrete boundaries that is composed of two or more tissue types. Microscopic anatomy: the study of tissues and how they are arranged into organs. Tissue- a group of similar cells and cell products working together to perform a specific role nan organ. The four primary tissues (epithelial, connective, nervous and muscular) differ from each other in: Relative amount of space occupied by cells versus matrix. Matrix (extracellular material) is composed of: fibrous proteins, clear gel called ground substance (also known as tissue fluid, extracellular fluid , interstitial fluid or tissue gel) Longitudinal section: tissue cut on its long axis. Cross section: tissue cut perpendicular to long axis of organ. Oblique section: tissue cut an angle between cross and longitudinal sections. Epithelia sheets of closely adhering cells, one or more cells thick. Upper surface usually exposed to the environment or an internal space in the body.
