Overview: Lung Sinew Channel (Arm Taiyin)

The Lung Sinew Channel and associated anatomy

1. The Lung sinew channel starts on the palmar aspect of the thumb and travels down to the base of the wrist to attach to the base of the first metacarpal and adjacent carpal bones. It then continues up the lateral aspect of the forearm to bind in the anticubital region. (Anatomy: Thenar muscles (Abductor pollicis brevis, Flexor pollicis brevis, Opponens pollicis), Flexor pollicis longus, Supinator)
2. This sinew channel will then travel up the anterior aspect of the arm to bind to the two attachments of the biceps. (Anatomy: Brachialis, Biceps brachii, Brachialis, Coracobrachialis)
3. One branch will travel under the clavicle following the subclavian artery and vein, over the first rib, and descend to the chest and diaphragm. (Anatomy: Subclavian artery and vein)
4. The second branch will travel to the anterior aspect of the ribs via the subclavius and pectoralis minor. (Anatomy: Subclavius, Pectoralis minor)
