what is joint
Dear Student,
A joint is a point or a location in our body where two bones make contact or are joined together. Joints are helpful in moving.
There are many types of joints, including joints that don’t move in adults, such as the suture joints in the skull. Joints that don’t move are called fixed. Other joints may move a little, such as the vertebrae.
Examples of mobile joints include the following:
1. Ball-and-socket joints. Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements.
2. Hinge joints. Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements.
3. Pivot joints. Pivot joints, such as the neck joints, allow limited rotating movements.
4. Ellipsoidal joints. Ellipsoidal joints, such as the wrist joint, allow all types of movement except pivotal movements.
Regards
