JOINTS

FIBROUS JOINTS- Lie between bones that closely contact one

another.- Thin layer of dense connective tissue joints

the bones.- Suture (skull)- Joint in leg between tibia and fibula (distal

end)

Page 2: JOINTS

CARTILAGINOUS JOINTS- Hyaline cartilage connect bones.- Joints of vertebral column- Intervertebral disc: fibrocartilage surrounding

a pulpy or gelatinous core.- Absorbs shocks and helps equalize pressure

between adjacent vertebrae when the body moves.

Page 3: JOINTS

SYNOVIAL JOINTS- Most joints are these type.- Allow free movement.- Complex structurally than fibrous or

cartilaginous- Articular ends covered with hyaline cartilage.

(articular cartilage) surrounded by a tubular capsule of dense connective tissue.

- Joint capsule: composed of an outer layer of ligaments and an outer layer of ligaments and an inner lining of synovial membrane (secretes synovial fluid).

- Synovial fluid: lubricates joints.- Menisci: flattened pads of fibrocartilage,

shock-absorber. Between the articulating surfaces of the bones.

Page 6: JOINTS

- bursae: fluid-filled sacs.- Located between tendons and underlying

bony prominences.- Aid movement of tendons that glide over

these bony parts or other tendons.

BALL-AND-SOCKET JOINT- Bone with a ball-shaped head that articulates

with the cup-shaped cavity of another bone.- Wider range of motion- Movements in all planes.Ex. Shoulder and hip
