What are ligaments primarily composed of?

Ligaments are primarily composed of strong bands of fibrous tissue. This composition is critical because ligaments serve to connect bones to other bones at joints, providing stability and support while allowing for a certain range of motion. The fibrous tissue is dense and contains a high concentration of collagen fibers, which contribute to the strength and flexibility needed to withstand tension and stress during movement. This structural makeup ensures that ligaments can effectively serve their primary function in the musculoskeletal system, maintaining joint integrity and preventing excessive movements that could lead to injury. Other tissues mentioned, like cartilage, adipose, and muscle fibers, do not provide the same structural composition or function as ligaments do.
