The classification model of the human bone lever consists of a sagittal section of the skull (including the mandible), a sagittal section of the cervical vertebrae from the 1st to the 5th, the lower part of the tibia and fibula, the talus bone, the humerus bone, the forearm bone, and the hand bone (showing the navicular bone and the head bone), the third metacarpal and the middle phalanx).
Connect the above bones according to the type of bone lever and label the fulcrum, force point, and resistance point of the lever, respectively. It is useful for teachers to intuitively explain and help students understand the conceptual classification of human bone levers and the role of the three types of bone levers in transferring force, counterbalancing force, saving labour and increasing range and speed of motion.
