Many layers, top cells flattened. Outer layer of skin. Line oral cavity, vagina, and anal canal.
Startified Columnar
Top layer of elongated cells, lower layer of cube-shaped cells. Line male urethra and part of pharynx.
Simple Squamous
Single layer, flattened cells. Line air sacs, blood vessels, and lymph vessels.
Transitional
Cube-shapes and elongated mixed up.Line urinary bladder, ureters and part of urethra.
Tissues
Similiar cells with common function. Study of tissues is called histology.
Unicellular Exocrine gland
Has one cell. Example goblet cell.
Elastic Fibers
Bundles of microfibrils embedded in elastin. Provide elastic quality to parts that stretch. Fibers branch. Vocal cords, air passages.
Adipose Tissue
Stores fat, cushions and insulates. Beneath skin, behind eyeballs, around kidney and heart.
Elastic Connective Tissue
Abundant in elastic fibers and some collagenous fibers. Has fibroblasts. Found in attachment between bones (spinal column) walls of large arteries, airways and heart.
Tight Junctions
Close space between cells by fusing membranes (base stitching)Simplest type. Located among cells that form linings.(small intestine)
