The medullary index is a ratio evaluating the width of the medulla of a hair to the width of the hair shaft. It’s decided by dividing the medulla’s diameter by the hair’s diameter. For instance, if a hair has a medullary diameter of fifty micrometers and a hair shaft diameter of 100 micrometers, the ensuing worth could be 0.5.
This calculation is a priceless instrument in forensic science and zoology. It assists in differentiating between human and animal hairs, as animals typically exhibit a better proportional medulla width. In forensic investigations, it could possibly slender down the potential sources of hair samples discovered at crime scenes. This measurement, whereas easy, supplies an vital attribute for identification and comparative evaluation.
