A bursa is a small fluid-filled sac. It provides a cushion between bones and tendons and/or muscles around a joint. Band of fibrous tissue connecting bone to bone or cartilage to bone thereby supporting or strengthening a joint.
So, how does a muscle connected to a bone?
A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones. The extra-cellular connective tissue between muscle fibers binds to tendons at the distal and proximal ends, and the tendon binds to the periosteum of individual bones at the muscle's origin and insertion.
What is the relationship between muscle and bone?
Bones don't work alone — they need help from the muscles and joints. Muscles pull on the joints, allowing us to move. They also help the body perform other functions so we can grow and remain strong, such as chewing food and then moving it through the digestive system.
What connects a bone to a bone?
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
