Human Skeleton Facts
Human skeleton is an important and complex structure. It gives shape to our body and helps us to move. It has some tasks like protecting organs, storing fat, making blood cells. Basically, human skeleton is divided into two sections: –
- The Axial Skeleton: – It is composed of the skull, the sternum, ribs and vertebrate column. It is located in the midline of the body. This section also includes some other smaller bones which are not connected.
- The Appendicular Skeleton: – This section of human skeleton is composed of limbs and their associated bones. Bones of hands, arms, feet and legs as well as the scapula (shoulder blade), the clavical (collar bone) and the pelvic bones.
