Approximately, how many bones are there in a child's body at the time of birth?

Correct option is B

​The correct answer is (b) 300 Bones

Explanation:

At birth, a human baby has approximately 300 bones. However, as the child grows, some of these bones fuse together to form larger and stronger bones. By adulthood, the total number of bones reduces to 206 due to this fusion process.

For example:

• The skull bones are initially separate but later fuse together.
• The sacrum in the lower spine forms from five vertebrae merging into one.

This natural process allows for flexibility and growth in a newborn’s body.

Bone Fusion Process in Humans

Newborn: ~300 bones
Adult: 206 bones (due to fusion)

Examples of bone fusion:

• Skull Bones: Babies have soft spots (fontanelles) that later harden.
• Vertebrae in Spine: Several small vertebrae fuse together in the sacrum and coccyx.

Why do babies have more bones?

• Helps in ease of childbirth (flexibility of skull bones).
• Allows for rapid growth and development.
