Why is it difficult to distinguish the skeleton of a young male from that of a young female?

subscapular fossa.

The corners of the scapula include (the)

superior angle, inferior angle, and lateral angle.

In the ankle, the only tarsal bone that articulates with the leg bones is the

talus.

The boundaries of the false (or greater) pelvis include

the bladelike portions of each ilium.

Age of a skeleton can be determined from

the degree of ossification of cranial sutures and the number of teeth present.
