| In the carpus the os magnum articulates freely with the scaphoid, and is separated from the cuneiform by the lunar and unciform. |
| This section passes through the fourth sacral vertebra and sacral hiatus and the os ilium at the sciatic notch. |
| The acetabulum is a hemispherical socket formed in the os coxae of a newborn where the ilium, ischium, and pubis bones come together. |
| The sacroiliac joints and the anterior superior spines of os ilium are seen in this cut. |
| The distance between the internal and external os was measured both as a straight line and also as a curved line along the endocervical canal. |
| In this group, the cortex of the os sacrum was destroyed and had a spongelike rather than compact appearance. |
