think of them as the frame that muscles
are built around, but in actual fact bones are one of the
primary organs of the body, and have many different functions
The rib cage, for instance, protects all the sensitive internal
organs that it envelops, like the heart
The skull, aside from giving structure to the head and face,
also protects our most sensitive organ of all, the brain.
Bones have several other important functions. The marrow they
contain helps produce blood cells, and they are essential
to many different kinds of mineral storage, including calcium.
of their structure, the bones
of the ear - the smallest in the human body - are also
essential to our hearing.
Bones, of course, are also beautifully engineered. They are
strong, hard, and yet relatively light. One of the primary
reasons for this is that bones are actually full of holes
on the inside, like a sponge or honeycomb structure.
are also somewhat elastic, owing to the support they get from
softer parts of the skeletal system such as cartilage, tendons
Keeping bones healthy
Made up of more than 200 different bones, the skeleton may be the
most under-appreciated parts of the human anatomy, and keeping
it healthy should be at the top of everyone's priorities.
deal of what we can do to keep bones strong comes down to
not significantly abusing them. Putting on a helmet while
or wearing other protective gear while engaged in sports,
are important considerations to keep bones from serious injury.
other hand, a little light abuse, while weight training for
example, will actually keep bones strong in much the same
that running keeps the cardio
system in top condition.
A proper diet is also essential to keeping bones healthy.
Weak bones are more susceptible to injury, and so a diet rich
will do bones a world of good.
supplements can also be taken with vitamin
D, a nutrient which research has shown to be absolutely
essential to bone health, especially later in life, to help
ward off such age-related conditions as osteoporosis.
