Detailed explanation-1: -A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have.

Detailed explanation-2: -Hint: The human skeleton refers to the internal framework of the body. 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.

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: -An adult human has a total 80 bones in the axial skeletal system and 126 bones in the appendicular skeletal system which makes a total of 206 bones in the entire human skeletal system. The axial skeleton system included skull(22 bones), rib cage(25 bones), vertebrae(26 bones), ear ossicles(6 bones) and hyoid bone(1).

Detailed explanation-5: -The adult human body contains 306 bones. Bicep is a/ an extensor muscle.
