    bone at the base of the great trochanter, and on the other to that portion of the preceding class of fibres which supports the upper surface of the head, as well as to the shell of bone between it and the trochanter. Both of these series are braced by other fibres, which are arranged at right angles to their direction. The cancelli of the great trochanter (<?) have no determinate form. The internal Plan of Neck of Femur. fibres thus act as braces, assisting the outer walls to support the weight of the body; the curved fibres (b, b) resisting by their tenacity, the straight or radiating ones (a, a) by their rigidity. The long straight fibres (a) transmit weight directly to the under side of the neck, and are themselves supported by the curved fibres (6, b), and these in turn by the radiating fibres (a). In the lower part of the femur and the tibia, the cancelli are adapted to support vertical pressure.
