Connective Tissues Functions: Bind structures together, support, transport, protection

Connective Tissues Functions: Bind structures together, support, transport, protection Contains few cells and an abundant intercellular matrix (Matrix = space between cells) The matrix is filled with fibers that are produced by the cells, including collagen fibers and elastic fibers

Types of connective tissue Loose (areolar): packing material. Attaches skin to underlying tissues. Fills the spaces between muscles.

Types of connective tissue Loose (areolar): packing material. Attaches skin to underlying tissues. Fills the spaces between muscles. Adipose tissue: Fat. Provides energy storage, cushioning around organs, and insulation

Types of connective tissue Loose (areolar): packing material Adipose tissue: Fat. Provides energy storage, cushioning around organs, and insulation Dense fibrous (collagenous): Forms tendons (connect muscle to bone) and ligaments (connect bones to each other)

Types of connective tissue Loose (areolar): packing material Adipose tissue: energy storage and cushioning Dense fibrous: Forms tendons (connect muscle to bone) and ligaments (connect bones to each other) Elastic: Can stretch and then return to normal length. Vocal cords, ligaments between vertebrae

Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible

Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton

Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton b. Fibrocartilage: strong shock absorber. Found in pads between vertebrae and in the knee

Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton b. Fibrocartilage: strong shock absorber. Found in pads between vertebrae and in the knee c. Elastic cartilage: more flexible. Found in external ear, epiglottis

Types of connective tissue 6. Bone: Most rigid connective tissue. Fibers are surrounded by calcium salts. Provides framework for body.
