These images from Netter's Atlas of Human Anatomy have been updated, highlighting the channels of Chinese medicine; where they live, what structures they are associated with, etc. At Dragon Rises College of Oriental Medicine, we observe these in cadaver lab and I created this resource for exploration of the channels in cadaver lab.
- LI 2-7. LI 2 - 4 access the 1st interosseus muscle, LI 5 is in the anatomical snuff box between the extensor pollicis longus and the extensor pollicis brevis and abductor pollicis longus. The rest of the channel is in the fascial border between the mobile wad of three (brachioradialis, extensor carpi radialis brevis and longus) and the extensor digitorum muscle group.
- SJ 2-8. SJ 2 and 3 access the 4th interosseus muscle, SJ 4 is in the fascial space between the extensor digitorum and the extensor digiti minimi. SJ 5 and 6 are on the radial side of the extensor digitorum muscle, but the channel is likely deep to this muscle and the needle would be advanced towards the ulnar side of the forearm. We will see this anatomy in the next group of images. SJ 7 returns to the fascial space between the extensor digitorum and the extensor digiti minimi. Again, the channel likely runs deeper than this layer and the target tissue will be seen in the next grouping of images. As the channel goes more proximal towards SJ 8, the extensor digitorum becomes flatter and less tendinous and the points are likely located in the belly of the finger extensor bundle.
- SI 2-6. SI 2-4 accesses the abductor digiti minimi muscle. SI 5 accesses the triangular fibrocartilage complex (TFCC) of the wrist and the needle is posterior to the flexor carpi ulnaris tendon. . SI 6 is between the extensor carpi ulnaris and the extensor digiti minimi and it also access the TFCC.. The channel returns to the space posterior to the flexor carpi ulnaris as it moves proximal from the wrist.
More will be added, check back soon
