Simple Columnar EpitheliumSimple Columnar Epithelium A single layer of cells that line the digestive tract, gallbladder and excretory ducts of some glands. Has microvilli at surface for absorption. Pseudostratified ciliated columnar epitheliumPseudostratified ciliated columnar epithelium Lines the bronchi, trachea, uterine tubes and some of the uterus. Propels mucus or reproductive cells by ciliary action.

Tissue protects and supports. Cell Matrix composed of two regions Ground Liquid (sol), Gel, Gum or solid Fibers Non-elastic (= white or Collagen) Elastic (= yellow fibers) Types of Connective tissue

- 14. Categories of Tissues Jenna Hellack Jan 2001 Dense Regular ConnectiveDense Regular Connective TissueTissue Nuclei and fibers arranged in parallel rows. Tendons and ligaments Fibers mostly non-elastic
- 15. Categories of Tissues Jenna Hellack Jan 2001 Adipose (Fat)Adipose (Fat) Function as storage cells for adipose (lipids) Adipose cells contain a large vacuole which in the live cell contains lipids. Cell nucleus and cytoplasm are pushed out to edge of cell membrane.
- 16. Categories of Tissues Jenna Hellack Jan 2001 CartilageCartilage Ground of matrix is gum like. Cells are found in Lacunae within the matrix. Fibers may be elastic or non-elastic, or a form of non-elastic called reticular(where the non-elastic fibers of very thin) Hyaline CartilageHyaline Cartilage-example on the ends of bones Elastic CartilageElastic Cartilage- example ear cartilage Non-elastic Cartilage- example nose cartilage.
