Types of fibrous joints (3)

Suture, Syndesmosis, Gomphosis

Types of cartilaginous joints (2)

Symphysis, Synchondrosis

Fibrous joints

Fibrous connective tissue joins the skeletal structures

Suture

Fibrous joint: Frequesntly serrated edges of articulating bones, separated by a thin layer of fibrous tissue; no movement

Syndesmosis

Fibrous joint: Articulating bones bound by a interosseous ligament; slight movement; e.g. joints between radius-ulna

Gomphosis

Fibrous joint: Periodontal ligament binding teeth into dental aveoli of bone; no movement

Cartilaginous joints

Fibrocartilage or hyaline cartilage joins the skeletal structures

Symphysis

Cartilaginous joint: Thin pad of fibrocartilage between articulating bones

Synchondrosis

Cartilaginous joint: Mitotically active hyaline cartilage between skeletal structures; no movement; e.g. ribs and costal cartilages

Synovial joints

Joint capsule between articulate bones, containing synovial fluid; extensive movement

Gliding

Synovial joint: Flattened or slightly curved articulating surfaces; sliding movement; e.g. intercarpal and intertarsal joints

Hinge

Synovial joint: Concave surface of one bone articulates with a depression of another; bending motion in one plane; e.g. elbow, joints of digits

Pivot

Synovial joint: Conical surface of one bone articulates with a depression of another; rotation about a central axis rotational movement; e.g. proximal radioulnar joint

Condyloid

Synovial joint: Oval condyle of one bone articulates with elliptical cavity of another; biaxial movement; e.g. wrist

Saddle

Synovial joint: Concave and convex surface on each articulating bone; wide range of movement; biaxial movement; e.g. carpometacarpal joint at base of thumb.

Ball and Socket

Synovial joint: Rounded convex surface of one bone articulates with cuplike socket of another; movement in all planes and rotation; e.g. hip joints and shoulder joints
