Zodiac Signs and the Human Body

Q: Could you kindly explain the mapping between the Signs and human body.
They say that Sign #1 is at the top of the body and #12 at the bottom, and the rest proceed in order. So Aries is the head, Taurus is the neck (some say Aries is the skull, Taurus is the face), Gemini is the shoulders, arms and hands. Cancer is the chest. Leo is the stomach. Virgo is the intestines. Libra is the hips / pelvis. Scorpio is the genital and anus. Sagittarius is the thigh. Capricorn is the knees. Aquarius is the calves/shins. Pisces is the feet.
