Your joints bend, but they don't fall apart. Ligaments are the strong straps that hold bones together, and fibrocytes take care of them.

A ligament is a strong strap that connects one bone to another bone at a joint. Your knees, ankles, wrists, and fingers all have them.
Ligaments are made mostly of collagen fibers. Fibrocytes are thin, flat cells tucked in between the fibers.
Bend and straighten your knee slowly. Ligaments inside are keeping the bones lined up while they move.
Ligaments stop your bones from sliding the wrong way. They let your knee bend forward and back, but not sideways.
Ligaments have few blood vessels, so a sprain can take weeks to heal. Rest helps the fibrocytes do their repair work.
