What Do the Ligaments Do in the Skeletal System?

By Demetria Jackson ; Updated July 27, 2017

The skeletal system provides support to the body, protection to internal organs and aids in movement in conjunction with the muscular system. Bones, ligaments and cartilage are structural components of the system.


By adulthood, the human body consists of 206 bones. Bones form the framework of the skeletal system and are responsible for manufacturing cellular blood components, such as red blood cells.


The point at which individual bones meet is called a joint and is where movement occurs. Bone surfaces are covered by cartilage at these joints to prevent erosion of the bone tissue.


Ligaments are made of tough, fibrous tissue and are found around the joints of the body. The ligaments connect the bone to bone at the union of the joint.

Ligament Function

Elastic in nature, ligaments allow for the controlled movement of joints. They reinforce joint integrity and strength.

Ligament Damage

Damage to ligaments may result in joint instability, additional bone on bone friction and impaired movement. A sprain is a type of ligament injury.
