Explain the types of joints.

Explanation

(i) Fibrous joints or Synarthroses: They are immovable fixed joints in which no movement between the bones is possible. Sutures of the flat skull bones are fibrous joints.
(ii) Cartilaginous joints or Amphiarthroses: They are slightly movable joints in which the joint surfaces are separated by a cartilage and slight movement is only possible.e.g., Joints of adjacent vertebrae of the vertebral column.
(iii) Synovial joints or Diarthroses joints: They are freely movable joints, the articulating bones are separated by a cavity which is filled with synovial fluid
e.g., Pivot joint - between atlas and axis plane/gliding joint - between the carpals
Saddle joint - between the carpal and metacarpal
Ball and socket joint - between humerus and pectoral girdle
Hinge joint - knee joint
Condyloid or angular or ellipsoid - joint between radius and carpal
