Corpus ossis femoris

The body of femur (or shaft of femur), is the almost cylindrical, long part of the femur.

It is a little broader above than in the center, broadest and somewhat flattened from before backward below.

It is slightly arched, so as to be convex in front, and concave behind, where it is strengthened by a prominent longitudinal ridge, the linea aspera.

It presents for examination three borders, separating three surfaces.

Of the borders, one, the linea aspera, is posterior, one is medial, and the other, lateral.
