The other name of the backbone is the vertebral column.

Joints and its Types

Joints are the areas where two or more bones meet and allow movement. There are three main types of joints in the human body:

1. Fibrous Joints: These joints are immovable and are held together by fibrous tissue. Examples include the joints between the bones of the skull.

2. Cartilaginous Joints: These joints allow limited movement and are held together by cartilage. Examples include the joints between the vertebrae of the spine.

3. Synovial Joints: These joints allow a wide range of movement and are the most common type of joint in the body. They are held together by a joint capsule and are lubricated by synovial fluid. Examples include the joints between the bones in the fingers and toes.

Synovial joints can be further classified into six different types based on their structure and movement:

1. Ball-and-Socket Joint: This joint allows for movement in all directions and is found in the hip and shoulder.

2. Hinge Joint: This joint only allows movement in one direction and is found in the knee and elbow.

3. Pivot Joint: This joint allows for rotational movement and is found in the neck and forearm.

4. Condyloid Joint: This joint allows for movement in two directions and is found in the wrist.

5. Saddle Joint: This joint allows for movement in two directions and is found in the thumb.

6. Gliding Joint: This joint allows for sliding movements and is found in the joints between the bones of the wrist and ankle.

In conclusion, understanding the different types of joints and their functions is essential in maintaining healthy and functional joints throughout life.
