Course of the Channels and Point Qualifications
### Small Intestine Channel (Hand-Taiyang)
Course: The Small Intestine Channel starts at the ulnar corner of the nail of the little finger and continues at the ulnar side of the hand through the wrist to the styloid process. From here it ascends in the ulnar aspect of the extensor carpi radialis muscle to the ulnar side of the olecranon. Then it ascends along the dorsal aspect of upper arm to the shoulder joint. From here it descends to the fossa infraspinata, traverses the scapular spine and ascends to SI 12. SI 12 meets with GV 14 and descends to ST 12 in the supraclavicular fossa. From ST 12 an internal pathway descends to connect with the heart. From there it continues along the esophagus to the stomach and the small intestine. From ST 12 a branch ascends along the lateral side of the neck to the corner of the jaw and the cheek to SI 18 below the zygomatic bone. An internal branch ascends from SI 18 to BL 01 at the inner canthus of the eye. Another branch ascends to the outer canthus of the eye, and enters the ear at SI 19. From SI 18 the Small Intestine Channel reaches SI 19 in front of the ear, its final point.
