ANATOMY

Detailed explanation-1: -This is because babies have more cartilage than bone. New born babies have around 305 bones. A baby’s skeleton is mostly made up of cartilage.As a person grows up, most of this cartilage turns into bone in a process called ossification.By adulthood, the skeleton has just 206 bones.

Detailed explanation-2: -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). Other bones in a baby are partly made of cartilage.

Detailed explanation-3: -Babies are born with around 300 cartilage parts that will eventually turn into 209 bones. Cartilage is dense connective tissue. This cartilage turns into hard bone through a process called ossification.

Detailed explanation-4: -Even so, at birth, many of your baby’s bones are made entirely of cartilage, a type of connective tissue that is tough, but flexible.

Detailed explanation-5: -Late in the second month of fetal development, a fetus’ skeleton is made up of thin membranes, which are about the thickness of paper tissue, and soft, flexible cartilage, like the kind you find in your ear. Over time, both types of tissue will turn into bone in a process called ossification.
