How Many Bones Are Present in Adult Humans?
The human skeletal system consists of 206 bones in adults. These bones provide support, protection, and mobility to the body. The bones are classified into two main categories: axial and appendicular. Axial bones include the bones of the head, neck, and trunk. Appendicular bones include the bones of the limbs and girdles.
The number of bones in the human body can vary slightly from person to person. Some people may have extra bones, such as an extra rib or a sesamoid bone in the knee. Others may have fewer bones, such as people who are born with a condition called agenesis, which is the absence of one or more bones.
The human skeleton is a complex and amazing system that allows us to move, breathe, and function properly. The bones are constantly being remodeled, which means that they are being broken down and rebuilt. This process helps to keep the bones strong and healthy.
