The adult human skeleton is made up
of at least 206 bones [a], and its number can be reached in some people,
including the Wormian bones, typically at 240. In the infant and the child
we must add 3 or more 4 sacral vertebrae, which subsequently fuse in the
sacrum, 3 to 5 coxigeal vertebrae, which are then fused in the coccyx, and the
ilium, ischium and pubis, which in the adult are fused in the coxal. Most
bones are even, with one member of each pair on each side of the body. The odd
bones are: the vertebrae, the sternum, the frontal, the occipital, the jaw, the
sphenoid, the ethmoid, the vomer and the hyoid
Children
have some more bones, which merge: Sacral vertebrae (4 or 5), which fuse in the
adult to form the sacrum. Coxigeal vertebrae (from 3 to 5), which fuse in the
adult to form the coccyx. Ilion, ischium and pubis, which fuse in the adult to
form the coxal. The total number of bones of the human skeleton is slightly
variable due to the existence of the wormians of the head, and the sesamoids of
the hands and feet
