The answer to the crossword is 'ANKLE'. The ANKLE is a joint between the foot and leg, located at the lower end of the leg. It is a complex joint that allows for movement in multiple directions, including up and down, side to side, and rotation. The ANKLE is made up of three bones: the tibia, fibula, and talus. It is held together by ligaments, tendons, and muscles. The ANKLE is an important part of the body, as it helps to support the body's weight and provides stability when walking or running.
