How many bones are in the human body?
The adult human body contains 206 bones. Anatomists separate these into two divisions: the axial skeleton, which contains the bones along the long axis of the body (i.e., the head and the torso) and the appendicular skeleton, which includes the bones of the appendages.

The Human Skeleton is a skeletal system composed of a strong framework of bones that supports the human body, protects internal structures, and allows for movement by providing points of attachment for muscles.
What are the functions of human skeletal system?
The human skeleton performs six major functions; support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation. The human skeleton is not as sexually dimorphic as that of many other primate species, but subtle differences between sexes in the morphology of the skull, dentition, long bones, and pelvis exist.
