Acupuncture Board Practice Exam: Practice Test & Study Guide

The small intestine meridian primarily ascends and connects to the heart. In Traditional Chinese Medicine, the flow of the small intestine meridian begins at the little finger, travels upward along the arm, and moves across the back of the shoulder to the neck, before it proceeds to the heart area and downward through the diaphragm. This upward movement is crucial as it facilitates the meridian's connections to organs and structures, allowing it to influence digestion and the assimilative processes in the body.

Understanding the direction of meridian flow is essential for practitioners, as it helps in the selection of acupuncture points along the pathway that can affect the small intestine's function and the overall interaction with other bodily systems. Hence, the direction of the small intestine meridian is designated as upward, indicating its important role in promoting health and balance within the body.
