Synovial joint application

What is the function of cartilage?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together.

• Strong, elastic fibres that hold bones together and keeps them in place

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.

What is the function of synovial fluid?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together.

• Strong, elastic fibres that hold bones together and keeps them in place

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.

What is the function of the synovial membrane?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together.

• Strong, elastic fibres that hold bones together and keeps them in place

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.

What is the function of the ligaments?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together.

• Strong, elastic fibres that hold bones together and keeps them in place. Acts as a stabiliser.

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.

What is the function of the joint capsule?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together; made up of out fibrous membrane and an inner synovial membrane.

• Strong, elastic fibres that hold bones together and keeps them in place

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.
