Ligamentler, or ligaments, are strong, flexible bands of connective tissue that connect bones to other bones at joints. They play a crucial role in stabilizing joints and allowing for a range of motion while preventing excessive movement that could lead to injuries. These structures are composed mainly of collagen fibers, which provide strength and elasticity. Ligamentler are essential for maintaining the integrity of the skeletal system and are found throughout the body, including in the knees, ankles, and shoulders, where they support various movements and activities.
