(There are a few other measurements sometimes given, butthey are of httle importance, and therefore are omitted.) How many true planes are there in the pelvis ? Name them andgive their direction. There are four—two anterior and two posterior z;2c?/»erZ anterior have a direction from above downward, from behind for-ward, and from without inward; the posterior from above downward,from before backward, and from without inward. What are the differences between the male and female pelvis?The real differences are found in the true pelvis, and are determinedby the presence of the uterus. Female. Shallow, but capacious. Light in structure, and the points for muscular attachments are much less angle 75°. Male. Deep. Bones stronger, heavier, rougher,and more compact. Pelvis more conical. Sacrum lessconcave. Ischial tu
