Joints are the regions present between two bones. Joints help in different body movements. Joints can be movable or fixed.
Fixed joints are those joints where movement is not possible. Example: Joints in the cranium or skull bone.
There are three main types of movable joints based on the type of movement they allow:
(i) Ball and socket joint: Allows rotational motion in all directions. Example: Shoulder joint and hip joint.
(ii) Pivot joint: Allows rotational movement in only one direction. Example:- Neck joint.
(iii) Hinge joint: Allows movement in only one direction i.e. back and forth movement. Example: Elbow joint and knee joint.
