Explanation:
Detailed explanation-1: -Skeletal muscles are connected to your bones by tough cords of tissue called tendons (TEN-duhns). As the muscle contracts, it pulls on the tendon, which moves the bone. Bones are connected to other bones by ligaments (LIG-uh-muhnts), which are like tendons and help hold your skeleton together.
Detailed explanation-2: -The locomotor system is also known as the musculoskeletal system. It is made up of the skeleton, skeletal muscles, ligaments, tendons, joints, cartilage and other connective tissue. These parts work together to allow your body to move.
