Understanding Joint Types: Fibrous, Cartilaginous, and Synovial

There are three main types of joints that hold bones together:

1. Fibrous joints: These joints are held together by fibrous connective tissue. They are the least movable type of joint and are found in the skull and between the teeth and jaw.

2. Cartilaginous joints: These joints are held together by cartilage. They are more movable than fibrous joints but less movable than synovial joints. Cartilaginous joints are found in the spine, pelvis, and ribs.

3. Synovial joints: These joints are the most movable type of joint and are found in the limbs, hands, and feet. Synovial joints are lined with a synovial membrane that produces a lubricating fluid that reduces friction between the bones.
