Detailed explanation-1: -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. This cartilage is soft and flexible. During childhood, as you are growing, the cartilage grows and is slowly replaced by bone, with help from calcium.

Detailed explanation-2: -Cartilage also gives a flexible shape and structure to places like the ears and nose. One example of a bone that babies are born without: the kneecap (or patella). The kneecap starts out as cartilage and starts significantly hardening into bone between the ages of 2 and 6 years old.

Detailed explanation-3: -Answer and Explanation: The skeleton of an embryo is mainly composed of hyaline cartilage. Cartilage is a tough and flexible type of connective tissue found in many parts of the body.

Short bones also evolve through endochondral ossification, but they are not structurally similar to long bones.

Detailed explanation-5: -Babies’ bodies need to be flexible and squishy so they can more easily pass through the birth canal. To ensure their skeleton is limber enough for the job, many of babies’ “bones” are actually made of soft and flexible cartilage, not bones as we know them, Dr.
