[header] How to read a hand reflexology chart [title] Look at the western hand reflexology chart. [step] This chart shows a connection between the fingertips and the upper part of the head, such as the sinuses, eyes, brain, ears. The palm of the hand contains the larger inner organs. <sep> (A) [substeps] Reproductive organs such as the testes, ovaries and fallopian tubes are found connecting to the inner wrist just beneath the hand. The thumb and the first 2 fingers contain more complex connections to the inner organs than do the outer 2 fingers. (B) From there, the hands are connected to the upper portion of the body by tiny, fluid-filled pieces of cartilage that move up and down. The upper part of the index finger leads to the heart and lungs, which is in turn linked. (C) The inner organs are examined by an ultrasound. If you have a custom diagnostic chart, see if you have a thought chart or some connecting diagram of a hand reflexology chart. (D) Note: almost all index cards have four index cards. This means that the index cards are the appropriate sizes for each reader and the recipients in the hand reflexology chart to know which card is more symmetrical than others.
