Femur

The femur (; : femurs or femora ), or thigh bone is the only bone in the thigh — the region of the lower limb between the hip and the knee. In many four-legged animals, the femur is the upper bone of the hindleg.

The leg bone of a deceased person is used. Alternatively, the leg bone of a respected teacher may be used. The kangling may also be made out of wood.
