Because skin and head musculature surrounding the skull represent a large shunt which can diffuse the applied current, first we examined the current loss between scalp and the brain.
While these suggest the possibility that the skull represents a male, this determination cannot be made with confidence on the current evidence.
The skull represents an advance over that of reptiles in the relatively larger cranium with fusion of elements, made possible by the fact that birds have a fixed adult size.
To ensure that BMD in the skull represents the mineral status of the skeletal system in general, a study was conducted where the BMD of the skull, one femur, and three lumbar vertebrae were compared in a subset of 13 free-ranging polar bears (3 subadults, 2 adult females, and 8 adult males) from Svalbard and East Greenland.

If anything, the skull represents the least individualistic thing that humans do, which is die.
To ensure that the BMD value in skull represented the mineral status of the skeletal system in general, we compared BMD values in femur and three lumbar vertebrae with skull in a subsample.
Entering the museum after perusing the excavation site from wooden platforms, the visitor faces a wall of 242 stone skulls, representing the enemy soldiers the Aztecs sacrificed to Huitzilpochtli, their god of war.
