“Furthermore, each leg of mine has seven sections—the coxa, the trochanter, the femur, the patella, the tibia, the metatarsus, and the tarsus.”

The first of these is called the 'coxa', and is succeeded by a short joint called the 'trochanter'.

They are really excretory glands, and communicate with the exterior by a very minute aperture on the posterior face of the coxa of the fifth limb on each side.

They consist typically of six segments, of which the basal is termed the coxa and the apical the tarsus.

Partial separations may be overlooked at the time of the accident and cause trouble later from bending of the bone, as in one variety of coxa vara.
