Mesocrania (from ancient Greek μέσος - middle and κρανίον - skull), mesokephaly (nephrocephaly) (from Latin mes-, middle, middle + cranium - skull) - the average size of the skull. Normally it is more than 75% of the average head length of the corresponding sex. The average skull length in newborns is about 34 ± 2 cm. Persons with mesocephaly are usually taller than those with large cranial dimensions, but their bodies are lighter due to longer limbs. Characterized by moderately prominent brow ridges. The term was coined by Neanderthal scientists. The relative mesocephalization of the dolichocephalic and brachycephalic types of combinations of the cerebral and facial parts of the skull has different meanings. The term is used mainly to characterize the human skull and is found when determining the degree of cranial deformation in animals.
Mesiocrania is often combined with macrocephaly or oligokephaly.
