What is a joint? Name its different types and explain any one of them.
A joint is a region where two or more bones meet. Different types of joints are:
1. Fixed joints or immovable joints
2. Slightly movable joints
3. Freely movable joints
Slightly movable joints: In these joints, flexible cartilage is present between the bones. The cartilage makes the slight movement possible. Their main function is to provide support. Examples of such joints include the joints between the ribs and the breast bone.
