heel
In mammals, the heel (regionally also heel (s) ) is the protrusion on the back of the foot . Their contours are obtained by the heel bone (from Latin calcaneus ) and the overlying adipose tissue and the skin . The heel is the starting point for the Achilles tendon , and the skin is slightly sunken on both sides of it.
The heel of the human foot
By the upright posture of man's heel assumes a more complex function than the lever arm of the Achilles tendon to form. Therefore, the tarsal bones in humans are very specific.
The gait pattern is the result of an interaction between the heel and the forefoot. The center of the heel is usually in line with the axis of the lower leg. She avoids the crease foot ( Latin valgus ) to the side (to lateral ) and the clubfoot ( Latin pes varus ) to the center (by the media ) from.
In the case of heel spurs , the x-ray shows a bony extension at the insertion of the Achilles tendon on the heel bone or at the origin of the plantar fascia (tendon plate of the sole of the foot).

In ancient mythology, the Achilles' heel was the only vulnerable point of the Greek hero Achilles .
