How do ligaments function in the skeletal system according to the text?

Ligaments function in the skeletal system by connecting one bone to another, forming joints. They are made of fibrous tissue and allow for movement in various directions, particularly in complex joints like the knee.

Ligaments are essential components of the skeletal system, serving to connect bones to each other or to cartilage. This connection helps form joints, which are crucial for facilitating movement. In complex joints, such as the knee, a series of ligaments work together to permit movement in different directions, enhancing the joint's functionality.
