 Structure:
The axial and the appendicular
skeletons make up the body's skeletal system, providing its' gross
features. Long bones, like the femur in
the leg or the humerus in the arm, short bones,
or like those in the fingers or feet, round bones, and like those of the
hand, and flat and irregular bones as are in the pelvis,
indicate the complexity of this system. Bones are nearly hollow, making
them light weight, with strength provided by a dense outside, cortical
portion. All bones are covered by periosteum from which they get their
circulation and nerves. Skeletal muscles attach
to periosteum at special places called orgins and insertions, where the
periosteum is thickened for making it strong.
 Function:
The primary function of the skeleton is locomotion,
but other important functions are maintaining posture,
protecting
internal organs, as the brain
inside the skull, providing a reservoir for minerals,
and serving as a site of hematopoiesis.
