Bursa is a small fluid-filled sac made of white fibrous tissue and lined with a synovial membrane It provides a cushion between bones and tendons and/or muscles around a joint. 

Other parts of the skeletal system include the tendons, joints, and ligaments. These terms are defined below:

Tendon: A tough and flexible band of fibrous connective tissue that connects the muscle to the bone. 

Ligament: A small band of dense, white, fibrous, and elastic tissue. Ligaments connect the ends of bones together in order to form a joint. 

Joint: Connect individual bones and may allow bones to move against one another in order to cause movement. There are two types of joints- diarthroses and synarthroses. Diarthroses allow extensive movement between two or more articular heads. Synarthroses, or false joints, do not allow for movement and very fibrous.
