Detailed explanation-1: -A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.

Detailed explanation-2: -In a nutshell, tendons and ligaments are both dense, soft tissues that connect different parts of the anatomy. For the most part, tendons attach bone to muscle, while ligaments attach bone to bone.

Detailed explanation-3: -Final answer: Tendons that attach skeletal muscle to bones and ligaments, which attach one bone to another are examples of dense regular connective tissues.

Detailed explanation-4: -Entheses (insertion sites, osteotendinous junctions, osteoligamentous junctions) are sites of stress concentration at the region where tendons and ligaments attach to bone. Consequently, they are commonly subject to overuse injuries (enthesopathies) that are well documented in a number of sports.

Detailed explanation-5: -Ligaments are tough fibrous cords composed of connective tissue that contains both collagen and elastic fibers. The elastic fibers allow the ligaments to stretch to some extent. Ligaments surround joints and bind them together. They help strengthen and stabilize joints, permitting movement only in certain directions.
