Anatomical Classification Of Joints

Front 1

Fibrous Joints

Back 1

adjacent bones bound by collagen fibers extending from the matrix of one into the matrix of the other

Front 2

Sutures

Back 2

immovable fibrous joints between cranial and facial bones (fibrous)

Front 3

Serrate Suture

Back 3

bones joined by a wavy line formed by interlocking teeth along the margins (fibrous)
(coronal, sagittal, and lamboid)

Front 4

Lap Suture

Back 4

bones beveled to overlap each other; superficial appearance is a smooth line (fibrous)
(squamos suture around temporal bone)

Front 5

Plane suture

Back 5

bones butted against each other without overlapping or interlocking (fibrous)
(palatine suture)

Front 6

Gomphosis

Back 6

insertion of a tooth into a socket held in place by collagen fibers of peridontal ligament (fibrous)

Front 7

Syndesmosis

Back 7

slightly movable joint held together by ligaments or interosseous membranes (fibrous)
(tibiofibular and radioulnar joint)

Front 8

Cartilaginous Joints

Back 8

adjacent bones held together by cartilage

Front 9

Synchondrosis

Back 9

bones held together by hyaline cartilage (cartilaginous)
(articulation of ribs with sternum, and epiphyseal plate uniting the epiphysis and diaphysis of a long bone of a child)

Front 10

Symphysis

Back 10

slighlty movable joint held together by fibrocartilage (cartilaginous)
(intervertebral joints and pubic symphysis)

Front 11

Synostoses

Back 11

former fibrous or cartilaginous joints in which adjacent bones have become fused by ossification
(midsagittal line of frontal bone, fusion of epiphysis and diaphysis of an adult long bone, and fusion of ilium, ischium, and pubis to form os coxae

Front 12

Synovial Joints

Back 12

adjacent bones covered with hyaline cartilage, separated by lubricating synovial fluid, and enclosed in a fibrous joint capsule

Front 13

Ball-and-Socket

Back 13

multiaxial diarthrosis in which a smooth hemispherical head of one bone fits into a cuplike depression of another (synovial)
(shoulder and hip joints)

Front 14

Hinge

Back 14

monaxial diarthrosis; able to flex and extend in only one plane (synovial)
(elbow, knee, and interphalangeal joints)

Front 15

Saddle

Back 15

joint in which each bone surface is saddle-shaped (concave on one axis and convex on the perpendicular axis); unique to the thumb (trapeziometacarpal joint) where it allows opposition (touching of thumb to fingertips (synovial)

Front 16

Pivot

Back 16

joint in which a projection of one bone fits into a ringlike ligament of antoher, allowing one bone to rotate on its longitudinal axis (synovial)
(atlantoaxial and proximal radioulnar joints)

Front 17

Gliding

Back 17

synovial amphiarthrosis with slightly concave or convex bone surfaces that slide across each other (synovial)
(intercarpal, intertarsal, and sternoclavicular joints; joints between the articular processes of the vertebrae)

Front 18

Condyloid

Back 18

biaxial diarthrosis in which an oval convex surface of one bone articulates with an elliptical depression of another (synovial)
(radiocarpal and metacarpophalangeal joints)
