The adult human skeleton is formed by 206 bones, which serve to protect our organs, support the body, reserve mineral salts (such as calcium) and produce blood cells (in the bone marrow).

We can divide it into axial skeleton (skull, vertebrae, ribs and sternum) and appendicular (upper and lower limbs and scapular and pelvic girdles).
