Answer:

Hey buddy here is your answer.......

Explanation:

1. Joints are the areas where 2 or more bones meet. Most joints are mobile, allowing the bones to move. Joints consist of the following: Cartilage. This is a type of tissue that covers the surface of a bone at a joint.

2.Examples of this form of articulation are found in the hip, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis; and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.

3.The pivot joint situated at the base of the skull, connects the first vertebrae of the spine to the second vertebrae. Thereby, allowing the side-to-side rotation of the head. A pivot joint permits movement of the bones in one plane, such as rotation around a single axis.

4.Hinge joints allow the movement of certain parts of the body in one plane. There are hinge joints in the fingers, toes, knees, elbows, and ankles. Although hinge joints are stable, people can still dislocate a bone in them.
