The standard anatomical position, or standard anatomical model, is the scientifically agreed upon reference position for anatomical location terms.

In medical disciplines, all references to a location on or ...
The human skeleton is composed of both fused and individual bones supported by ligaments, tendons, muscles and cartilage. It is a complex structure with two distinct divisions; the axial skeleton , which includes the vertebral column , and the appendicular skeleton .
The human pelvis exhibits greater sexual dimorphism than other bones, specifically in the size and shape of the pelvic cavity, ilia, greater sciatic notches, and the sub-pubic angle. The Phenice method is commonly used to determine the sex of an unidentified human skeleton by anthropologists with 96% to 100% accuracy in some populations. [11]

[3] Many small accessory bones, such as sesamoid bones, are not included in this.
