Tumor of the Bone Anatomy

To better understand a bone tumor, it helps to understand bone anatomy.

The skeleton is a living structure that supports the entire body. Bone is made up of an outer shell of very dense bone that surrounds a honeycomb-like structure of softer bone. Bone mainly consists of protein and calcium. Without calcium, bone will become weak.

The human skeleton can be divided into two sections:

  • Axial skeleton:
    • A total of 80 bones including the skull, spine, and chest
  • Appendicular skeleton:
    • A total of 126 bones including the pelvic girdle, limbs, feet and hands

Anatomy examples:
  • Internal structure of bone
  • The pelvic girdle
  • The chest
  • The skull
  • The spine
  • Skeletal system
  • Lower extremity
  • Hands and wrists
  • Feet
