I believe that planetary rulership and condition of each in signs and houses can easily be seen by looking at physical appearance. The same principles apply to medical astrology. In fact, I think using external appearance can work out how the chart actually looks like.
I have Moon in Capricorn and Pluto square Moon.
Mars in Virgo conjuncts Venus in Libra both 1st house, when I was younger and even now, I still have dry but oily skin with blemishes.
Mars is inflammation, Saturn is dry in nature, Venus conjuncts Mars, Venus and Mars rule sexual hormones, natal Neptune square both, personally it represents illusion applied to the first house, Neptune=make up.
Venus and Saturn (+joints) in medical astrology both rule skin (Venus sensory system of the skin & pores and Saturn rules the Skin. 1st house is the head.
Saturn rules aging, as we age it manifests itself on skin as wrinkles.
Same as people with facial/head injury, you can have a look of the conditions of 1st house, Aries, Mars and Ascendant etc. You can use reverse methods to check your chart out.
Sun rules Heart, Circulation system, eyes,
Moon rules the other side of circulation system, body fluid as she rules all water with Neptune, eyes with Sun
Mars rules Muscular system, physical energies
Venus rules Sensory system, the pores, venous blood system, pleasure-producing system
Jupiter rules Arterial Circulatory system, the process of growth, expansion
Saturn rules skeletal system, skin, aging process, restriction
Uranus rules Sympathetic nervous system
Neptune rules Spinal canal, all drugs, anything that dissolves such as oxygenation process between air we breath in and dissolve into haemagoblin
Pluto rules Excretory System, sexual organs, with Mars both rule regeneration functions, both Mars and Pluto fight and heal
Each sign rules different part/s of the body. Look for your dignified/fall/detriment planets in their own sign, house and in exaltation sign or friendly/unfriendly houses, and compare them with your physical appearance.
