Question

what is a joint? name four types of joints in the human body

Answer 1

Answer:

A joint is the part of the body where two or more bones meet to allow movement.

• Ball-and-socket joints. Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements.
• Hinge joints. Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements.
• Pivot joints. Pivot joints, such as the neck joints, allow limited rotating movements.
• Ellipsoidal joints. Ellipsoidal joints, such as the wrist joint, allow all types of movement except pivotal movements.
