Simple biology teaches us that,
generally, the bone protects the delicate organs of the body — in
addition to being the framework that props up the skin and gives it
shape. Without the bones, the skin would just be a drag, literally.
Scientists say at birth, we have about
270 bones, which systematically fuse together as we grow. By the time we
reach adulthood, the normal adult human has 206 bones in all; and this
underscores the importance of the skeleton to overall human health.
Bone functions
Scientists say the skeleton provides the
framework that supports the body and maintains its shape. For instance,
they say, without the rib cages, costal cartilages, and intercostal
muscles, the lungs would collapse.
Again, the joints between bones allow
movement, with some allowing a wider range of movement than others.
“Movement is powered by skeletal muscles, which are attached to the
skeleton at various sites on bones. Muscles, bones, and joints provide
the principal mechanics for movement, all coordinated by the nervous
system,” scientists enthuse.
