A synovial cavity is found in ________ joint

Freely movable joints are those that can move in one or more directions. A synovial joint is a prime example. In these joints:

• The bones are enclosed within a synovial membrane.
• Inside, there is a synovial cavity filled with synovial fluid.

The synovial fluid plays several crucial roles:

• Acts as a lubricant, reducing friction between bones.
• Provides nutrients to the bones.
• Allows movement in multiple directions.
• Functions as a shock absorber during falls or sudden jerks.

Types of Synovial Joints:

1. Ball and Socket Joint: Found in the hip (femur and pelvis) and shoulder (clavicle and scapula); allows movement in all directions.
2. Hinge Joint: Found in toes, fingers, and elbows; allows movement in one plane like opening and closing.
3. Gliding Joint: Found in wrists and ankles; allows sliding movements between bones.
4. Pivot Joint: Found between the atlas and axis (first two cervical vertebrae); allows rotational movement.
5. Saddle Joint: Found between metacarpals; allows movement back and forth and side to side.
