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. Bones are made of connective tissue reinforced with calcium and specialised bone cells.
Detailed explanation-2: -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-3: -The baby skeleton has more bones and cartilages. During development many of these cartilages become bones by the process called ossification and some bones fuse to form a bigger bone reducing the number of bones to 206.
Detailed explanation-4: -Slowly, as you grew older, everything became a bit bigger, including your bones. 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 adult human body contains 306 bones. Bicep is a/ an extensor muscle.
