How do movable joints allow movement for the bones?
With the help of muscles, joints work like mechanical levers, allowing the body to move with relatively little force. The surfaces of bones at joints are covered with a smooth layer of cartilage that reduces friction at the points of contact between the bones.

What are the 4 movable joints?
Types of freely movable joints
- Ball and socket joint. Permitting movement in all directions, the ball and socket joint features the rounded head of one bone sitting in the cup of another bone.
- Hinge joint.
- Condyloid joint.
- Pivot joint.
- Gliding joint.
- Saddle joint.
Which joints are movable and immovable?
Bones at cartilaginous joints connected by cartilage and are slightly movable. Bones at fibrous joints are immovable and connected by fibrous connective tissue.
What joint is freely movable?
Diarthroses
Diarthroses. Most joints in the adult body are diarthroses, or freely movable joints. The singular form is diarthrosis. In this type of joint, the ends of the opposing bones are covered with hyaline cartilage, the articular cartilage, and they are separated by a space called the joint cavity.
