PATHOLOGY

Detailed explanation-1: -There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult.

Detailed explanation-2: -It consists of 270 to 300 bones at birth. But this total number of bones decreases to 206 bones by adulthood as some bones fuse together. There are 80 bones in the axial skeleton and 126 bones in the appendicular skeleton.

Detailed explanation-3: -As your baby grows into childhood, much of that cartilage will be replaced by actual bone. But something else happens, which explains why 300 bones at birth become 206 bones by adulthood. Many of your baby’s bones will fuse together, which means the actual number of bones will decrease.
