Fibrous- | Articulating bones fastened together by a thin layer of dense connective tissue containing many collageneous fibers. |
Fibrous Syndesmosis- | bones are bound by long fibers of connective tissue that form an interosseous ligament because it's flexible and may be twisted. may permit slight movement and is amphiarthrotic. ex/ distal ends of tibia and fibula |
Fibrous Suture- | only between flat bones of the skull united by sutural ligaments. since they are immovable they are synarthroic. ex/ parietal bones articulate at sagittal suture of skull |
Fibrous Gomphosis- | a joint formed by the union of a cone shaped bony process into a bony socket. ex/ root of tooth united with mandible |
Cartilaginous- | articulating bones connected by hyaline or fibro cartilage |
Cartilaginous Synchondrosis- | bones united by hyaline cartilage. ex/ between epiphysis and diaphysis of long bone. movement occurs during growth process |
Cartilaginous Symphysis- | covered by a thing layer of hyaline cartilage which is attached to a pad of spongy fibrocartilage. ex/ joints between bodies of vertebrae, the symphysis pubis in the pelvis which allows bones to shift when child birth takes place. limited movement |
Synovial- | articulating bones surrounded by a joint capsule of ligaments and synovial membranes; ends of articuating bones covered by hyaline cartilage and seperated by synovial fluid |
Synovial Ball and Socket- | ball shaped head of one bone articulates with a cup shaped pocket of another. ex/ shoulder and hip movements in all planes; rotation |
Synovial Condyloid- | the condyle of one bone fits into the elliptical cavity of another bone ex/ joints between the metacarpals and phalanges permits a variety of movement in different planes, but rotational movement is not possible |
Synovial Gliding- | surfaces are nearly flat or slightly curved. ex/ most joints within the wrist and ankle. these joints allow sliding or back and forth motion and twisting movements. |
Synovial Hinge- | the convex surface of one bone fits into the concave surface of another. ex/ the elbow and the joints of the phalanges. this joint resembles the hinge of a door because it permits movement in 1 plane only. |
Synovial Pivot- | the cylindrical surface of one bone rotates within a ring formed of bone and fibrous tissue of a ligament. the joint between the proximal ends of the radius and ulna. movement is limited to rotation around a central axis. |
Synovial Saddle- | forms between bones whose articulating surfaces have both concave and convex regions. the surface of one bone fits the complimentary surface of another. ex/ the joint between the carpal and metacarpal of the thumb. permits a variety of movements 2 planes |
