9.4b types of synovial joints
Saddle joint
Articular surfaces of the bones have convex & concave regions that resemble the shape of a saddle.
Metacarpophalangeal
Biaxial condylar joints
Condylar joints
Biaxial joints with an oval, convex surface on one bone that articulates with a concave articular surface on the second bone.
Carpometacarpal
Biaxial saddle joint
Uniaxial
Bone moves in just one plane or axis.
Multiaxial
Bone moves in multiple plane or axis.
Biaxial
Bone moves in two planes or axes.
Pivot joint
Is a uniaxial joint in which one articulating bone with a rounded surface fits into a ring formed by a ligament & another bone
Hinge joint
Is a uniaxial joint in which the convex surface of one articulating bone fits into a concave depression on the other bone.
Hip joint & glenohumeral joints
Multiaxial ball-and-socket joints
Ball-and-socket joints
Multiaxial joints in which the spherical articulating head of one bone fits into the rounded, cuplike socket of a second bone.
Elbow and knee joints
Uniaxial Hinge joint
Intercarpal and intertarsal joints
Uniaxial Plane joint
Atlantoaxial & radioulnar joint
Uniaxial pivot joint
Plane joint
Uniaxial. Simplest synovial articulation and the least mobile type of diarthrosis.
