Document Summary
Densely packed, randomly arranged, collagen fibers and few visible cells. Locations: deeper layer of skin (dermous), capsules around organs. Adipose tissue (fat) - tissue in which adipocytes are the dominant cell type. Space between adipocytes is occupied by areolar tissue, reticular tissue and blood capillaries. Empty looking cells with thin margins; nucleus pressed against cell membrane. Contributes to body contours - female breasts and hips. Color comes from blood vessels and mitochondrial enzymes. Gives shape to ear, tip of nose, and larynx. Cartilage cells that produce the matrix that will trap them. Cartilage cells that are trapped in lacunae (cavities) Sheath of dense irregular connective tissue that surrounds elastic and most hyaline cartilage (not articular cartilage) Contanis a reserve population of chondroblasts that contribute to cartilage growth throughout life. Matrix rich in gags and contains collagen fibers. Clear, glassy appearance because of fineness of collagen fibers. Eases joint movement, holds airway open, moves vocal cords, growth of juvenile long bones.
