GENERAL CHARACTERISTICS

MAJOR CELL TYPES

CONNECTIVE TISSUE FIBERS

CATEOGORIES OF CONNECTIVE TISSUES

connects, suports, protects, provides frameworks, fills spaces, stores fat, produces blood cells, protects against infection, and helps repair damaged tissue

tissue cells usually have considerable extracellular matrix between them

consists of fibers and a ground substance

Fibroblasts- produce collagen and elastic fibers

Macrophages- phagocytes, eat cells

Mast cells- may release heparin and histamine

Collagen fibers- have a great tensile strength

Elastic Fibers- are composed of elastin and are stretchy

Reticular Fibers- fine collagen fibers

Loose Connective Tissue

Dense Connective Tissues

Specialized Connective Tissue

Areolar- forms thin membranes between organs and binds them together. Found beneath the skin and surrounds organs

Adipose- stores fat, cushions, and insulates. Beneath the skin, certain abdominal membranes; and around the kidneys, heart and various joints

Reticular- thin branched reticular fibers. Supports the walls of the liver and spleen.

Dense Regular- strong collagen fibers that bind structures as parts of tendons and ligaments

Dense Irregular- thicker, randomly distributed collagen fibers and is found in the dermis

Elastic- elastic fibers that make up hollow internal organs like the lungs and blood vessels.

Cartilage- provides support. consists of fibers and a gel like substance. Lacks a direct blood supply, slow to heal. Found at the end of various bones; in the ear; in the larynx; and in the pads between the bones of the spinal column, pelvic girdle, and knees

Bone- matrix consists of mineral salts and collagen. compact and spongy bones. heals rapidly.

Blood- composed of cells suspended in fluid. Produced in the tissue of hollow parts of certain bones.
