Medical astrology, or in ancient Greece it was called iatromathematica, is the ancient medical system that associates various parts of the body and diseases with the 12 astrological signs of the zodiac and other celestial bodies. One of the earliest written references that gave the descriptions of the birth signs and related body parts dates back to Marcus Manilius' "Astronomica" in the first century A.D.

Learn a little bit about each birth sign and its related body parts.

Taurus rules the throat, including the neck, thyroid gland and vocal tract. Taureans often have a long or thick neck, or their neck is a stand out feature. Taureans can have a tendency to have sweet sounding voices or a musical inclination.


Gemini rules the nervous system, which includes the shoulders, lungs, arms, hands and fingers.
