Study Notes
Human Skeleton Overview
- The human skeleton is the internal framework of the human body.
- It is composed of approximately 270 bones at birth.
- This number decreases to around 206 bones by adulthood due to bone fusion.
Bone Mass
- The bone mass in the skeleton makes up about 14% of the total body weight.
- The average bone mass is around 10-11 kg for an average person.
- Bone mass reaches its maximum between the ages of 25 and 30.
Skeletal Division
- The human skeleton can be divided into two main parts: axial skeleton and appendicular skeleton.
Axial Skeleton
- The axial skeleton is formed by the vertebral column, rib cage, skull, and other associated bones.
Appendicular Skeleton
- The appendicular skeleton is attached to the axial skeleton.
- It is formed by the shoulder girdle, pelvic girdle, and bones of the upper and lower limbs.
