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: -This is because a baby’s bones aren’t fully formed and are joined together with a tough but flexible tissue called cartilage, which helps protect the baby, and the mother, during birth. As a child grows, the cartilage hardens and turns to bone, fusing the parts together-a process known as ossification.

Detailed explanation-4: -During childbirth, the flexibility of the sutures allows the bones to overlap so the baby’s head can pass through the birth canal without pressing on and damaging their brain. During infancy and childhood, the sutures are flexible.

Detailed explanation-5: -During adulthood (about 18–25 years) the occipital bone and the sphenoid bone fuse into a single unit. The frontal bone at birth consists of two halves separated by the metopic suture.
