ellipsoid joint
characterized by a spherical head fitting into a cup-like depression
Ball-and-socket joint

What type of structure is a bursae

The Joint Capsule is made of 2 parts
synovial membrane & fibrous capsule
function of synovial fluid
lubricates the joint, reduce friction & provide nutrients to articulating cartilage
role of a ligament in the joint structure
Reinforce the joints by keeping the bones together
