| Question | Answer |
|---|---|
| An immovable joint or slightly movable joint united by the sheets of fibrous tissue. The inferior tibiofibular joint is an example. | Syndesmosis |
| An immovable joint occurring only in the skull. In this joint the interlocking bones are held tightly together by strong connective tissues. The sutures of the skull are an example. | Suture |
| An immovable joint occurring only in the roots of the teeth. The roots of the teeth that lie in the alveolar sockets are held in place by fibrous peridontal ligaments. | Gomphosis |
| A slightly movable joint. The bones in this joint are separated by a pad of fibrocartilage. The ends of the bones contain hyaline cartilage. Ex. pubic symphysis and the joint between each vertebral body. These joints all contain fibrocartilaginous pad or | Symphysis |
| An immovable joint. This joint contains a rigid cartilage that unites two bones. An example is the epiphyseal plate between the epiphysis and diaphysis of a growing long. | Synchondrosis |
| Uniaxial movement. This is the simplest synovial joint, permit slight movement. They have flattened or slightly curved surfaces, and most glide slightly in only one axis. Ex.: intercarpal and intertarsal joints of the wrist and foot; carpometacarpals (2-5 | Gliding (plane) |
| Uniaxial movement. Permits only flexion and extension. Ex.: elbow joint, interphalangeal, humeroulnar, and humeroradial articulatons. | Hinge (ginglymus) |
| Uniaxial movement. Allow only rotation around a single axis. A rounded or pointed surface of one bone ariculates within a ring formed partially by the other bone. Ex.: Distal and proximal radioulnar joint. | Pivot (trochoid) |
| Biaxial movement. Permits movement in two directions at right angles to each other. Flexion, extension, abduction, adduction and circumduction. Ex.: radiocarpal and metacarpophalangeal joint. | Ellipsoid (condyloid) |
| Biaxial movement. This joints permits movement in two axes, similar to the ellipsoid joint. Ex.: carpometacarpal joint of the first digit. | Saddle (sellar) |
| Multiaxial movement. This joint permits movement in many axes: flexion and extension, abduction and adduction, and circumduction, and rotation. | Ball and socket (spheroid) |
| The study of the joints, or articulations between bones. | Arthrology |
