The term of the ankle bone is 'tarsal', which is a six-letter word. Tarsals are a group of bones in the foot that form the ankle joint and help support the body's weight when standing and walking. They are located between the tibia and fibula, two long bones in the lower leg, and the metatarsals, five long bones in the foot. The tarsals are the most proximal of the bones in the foot and are responsible for providing stability and flexibility to the ankle joint.
