The truepelvis is all that por-tion which is situatedbeneath the linea ilio-pectinea. This lineforms the margin orbrim of the true pelvis,while the included areais called the inlet. Theform of the inlet isheart-shaped, obtuselypointed in front at thesymphysis pubis, ex-panded on each side,and encroached uponbehind by a projectionof the upper part of the sacrum, which is named the cavity is somewhat encroached upon at each side by a smoothquadrangular plane of bone, corresponding with the internal surfaceof the acetabulum, and leading to the spine of the ischium.
