The foot is an amazing and intricate structure. The bones in
your feet make up about one fourth of all the bones in your body.
Each foot contains 26 bones. It takes 33 joints, 107 ligaments,
19 muscles, and numerous tendons to hold the bones in place and
to move in a variety of ways. In addition, each foot has about
125,000 sweat glands which excrete as much as a half
a pint of moisture each day.
The human foot is comprised of:
- Seven thick, short, tarsal bones which compose the heel and
back of the instep.
- Five parallel metatarsal bones that form the front of the
instep. They spread toward the front of the foot to form the ball
of the foot.
- Fourteen smaller phalanges which make up the toes (the large
toe has two, each smaller toe has three).
- Tough bands of tissue (ligaments) which connect the bones and
hold them in place.
- The tarsal and metatarsal bones which form the two arches of
the foot.
- A thick layer of fatty tissue under the sole, which helps the
arches absorb the pressure and shocks of walking, running, and
jumping.
