English[edit]
Noun[edit]
cranial index (plural cranial indices or cranial indexes)
- (medicine, anthropology) A measure of the elongation or flatness of a head or skull: the maximum breadth of the skull divided by its maximum length, multiplied by 100.
- The width of the skull is 18 cm and the length 24 cm, so the cranial index is 75.
See also[edit]
- cranial ratio (expressed as a fraction or percentage)
- cephalic index/ratio (a distinction is sometimes made that the cephalic index applies to living heads and the cranial index to bones, but this is not consistently observed)
