Classification of Synovial Joints According to Shape

Question 1

• have only a slight gliding movement between relatively flat apposed surfaces.
• These surfaces are called facets.
• INTERVERTEBRAL JOINTS

Answer 1

Plane Joint

Question 2

• permits movement in nearly any direction.
• A spherical head on one bone fits into a cup-shaped depression in the other.
• SPHEROID
• SPHEROIDAL JOINT
• SHOULDER JOINT

Answer 2

Ball-and-Socket Joint

Question 3

• has an articular surface that is expanded more in one direction than another, forming an ellipse.
• The reciprocal convex (male) and concave (female) elongated surfaces of the radiocarpal articulation form an ellipsoidal joint.
• ATLANTO-OCCIPITAL JOINT

Answer 3

Ellipsoidal Joint

Question 4

• permits flexion and extension with a limited degree of rotation.
• FETLOCK JOINT

Answer 4

Hinge Joint

Question 5

• The surfaces of such a joint include rounded
  prominences, or condyles, that fit into reciprocal depressions or condyles on the adjacent bone, resulting in two articular surfaces usually included in one articular capsule.
• FEMOROTIBIAL JOINT

Answer 5

Condylar Joint

Question 6

• TROCHOID
• one in which the chief movement is around a longitudinal axis through the bones forming the joint.
• ATLANTOAXIAL JOINT

Answer 6

Pivot Joint

Question 7

• characterized by opposed surfaces, each of which is convex in one direction and concave in the other, usually at right angles
• PASTERN JOINT

Answer 7

Saddle Joint

Question 8

Tarsal Joint

Answer 8

Cochlear Joint

Question 9

Femoropatellar Joint

Answer 9

Sledge Joint
