The relationship of the anterior branch of the axillary nerve to the deltoid muscle was studied on both sides in 66 adult cadavers. The nerve runs a course on the deep surface of the deltoid muscle about 2.2 cm above the midpoint on the vertical plane of the muscle.

The orbital groove, the groove for the orbital branch of the middle meningeal artery, the meningo-orbital foramen and the foramen spinosum have been studied in 100 human skulls. The orbital groove is present in about 30% of skulls.
The surface areas of the occipital condyles of 101 skulls and of the superior articular facets of 103 atlases have been measured to ascertain bilateral asymmetry and dominance. The atlases show a tendency to have larger facets and the occipital bones tend to have larger condyles on the right side.

The soleal line in 167 left and 163 right tibiae has been studied. The line often does not follow the textbook description. It commences well below the fibular facet and ends well down nearer the middle of the bone on the medial border. It generally shows mixed characters of a line, a wide line, a ridge, or a groove. The line is frequently absent in the upper third. In the middle third, it is seen as a wide or as a ridge varying from 1 to 2 mm in height. In the lower third the line presents itself as a ridge. In the middle and lower thirds, the line is often seen as a depression varying from 1 to 2 mm in depth. The line shows a left-sided dominance.

1770 phalanges of the hand and 660 phalanges of the foot, of unknown sex, were studied to determine the number, position and direction of the nutrient foramina. It was found that, in general, these bones had one nutrient foramen in the middle third of the shaft. The proximal phalanges of the fingers often showed double foramina. Most of the foramina were situated on the border between the palmar/plantar and dorsal surfaces. The distal phalanges of the toes, and particularly of the great toe, may have a nutrient foramen on the dorsal surface. In the intermediate phalanges of the toes it is not possible to identify the nutrient foramen with certainty. All the foramina were directed away from the growing end.
