Why is our backbone slightly movable?

The combination of small movements between each successive vertebral attachment is what allows the vertebral column to move as a unit, that is, to flex and extend.

Why are slightly movable joints important?

Slightly movable joints permit some movement but provide less stability than immovable joints. These joints can be structurally classified as cartilaginous joints, as bones are connected by cartilage at the joints. Cartilage is a tough, elastic connective tissue that helps to reduce friction between bones.

What is another name for slightly movable joints?

Slightly movable joints are called amphiarthroses. The singular form is amphiarthrosis. In this type of joint, the bones are connected by hyaline cartilage or fibrocartilage. The ribs connected to the sternum by costal cartilages are slightly movable joints connected by hyaline cartilage.

synovial jointsDiarthroses (freely movable). Also known as synovial joints, these joints have synovial fluid enabling all parts of the joint to smoothly move against each other. These are the most prevalent joints in your body. Examples include joints like the knee and shoulder.

What are the six types of joints?

Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint. The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints (Figure 9.4.
