Document Summary

Connective tissue - supports muscular tissue - moves nervous tissue - controls. Epithelial covers a body surface or lines a body cavity lines passageways that communicate with outside world covers walls and organs in the ventral body cavities characteristics - specialized contacts between epithelial cells. Nerve supply (= innervated) but no blood vessels in tissue (= avascular) Named according to: shape of cell & type of layering of cells. Found: alveoli of lungs, serous membranes, lining of heart and blood vessels. Found: outer layer of skin, linings of oesophagus, trachea. Found: kidney tubules, ducts and secretory sections of small glands. Found: digestive tract (secretory), bronchi, uterine tubes (ciliated) Connective made up of specialised cells, fibres (collagen, elastin, reticular), ground substance the fibres and the ground substance make up the extracellular matrix that surrounds the cell classifications: Loose connective tissue - areolar tissue, adipose tissue. Dense connective tissue - deep fascia, tendon and ligament.
