How many bones are in the human body?

  1. 154

  2. 272

  3. 206

  4. 189

The correct answer is: 206

The human body typically has 206 bones in adulthood. This number can vary during childhood, as infants are born with approximately 270 bones. Over time, some of these bones fuse together, which is why the total number decreases as a person matures. Adult bones, such as those in the skull and spine, gradually unify, leading to the standard count of 206. This knowledge is important in fields such as anatomy and nursing, as understanding the skeletal structure is essential for patient care and assessment.
