Detailed explanation-1: -Bones provide the structure for our bodies. The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs.
Detailed explanation-2: -The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.
Detailed explanation-3: -There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult. The reason for the variability in the number of bones is because some humans may have a varying number of ribs, vertebrae, and digits.
Detailed explanation-4: -A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij).
Detailed explanation-5: -The human skeleton is the internal framework of the body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together.
