Everything You'll Have Covered

What are joints?

Joints are special skeletal structures that serve to allow connected bones to move freely and to prevent them from rubbing against one another.

What are the physical characteristics of movable joints?

Immovable, or fixed, joints are generally stationary and allow for little, if any, movement. In many cases, immovable joints often look like a single piece of bone.

What are some examples of immovable and movable joints?

Immovable joints can be found in the skull and the pelvic girdle. Joints that connect the teeth to the jaw are also immovable. Examples of movable joints include the lumbar and dorsal vertebrae, and joints in both our arms and legs.

How are the ends of the bones that make up joints protected from one another?

The ends of the bones that come together in a joint are protected by cartilage and synovial fluid, which makes the ends of the joints smooth and slippery so that bones can move freely.
