• To connect bones with fibrous tissue

• To allow smooth movement between bones
• To provide a rigid connection between bones

• To store minerals

(a)   is a type of synovial joint.

• Condyloid
• Fibrous
• Cartilaginous

What is the function of synovial fluid in synovial joints?

• It increases friction between surfaces

• It reduces friction and absorbs shock

• It hardens the cartilage

• It decreases the joint angle

Synovial fluid's viscosity changes with joint activity, (a)   during activity and (b)   at rest.
