43 is about one-fifth the number of Bones in the Human Body
In other words, it's 0.2090 times the count of Bones in the Human Body, and the count of Bones in the Human Body is 4.780 times that amount.
(adult, excluding sesamoid bones and ossicles)
The adult human body contains 206 bones. A newborn's body contains more bones — 270 — with unfused bone segments in the legs, arms, head, and face.
