Skin-subcutaneous tissue-trapezius muscle-rhomboid muscle-superior posterior serratus muscle-splenius muscle of neck-erector spinal muscle.
In the superficial layer, there are the medial cutaneous branches of the posterior branches of the 1st and 2nd thoracic nerves and the medial cutaneous branches of the accompanying posterior intercostal arteries and veins. In the deep layer, there are the muscuuar branches of the posterior branches of the 1st and 2nd thoracic nerves and the branches of the dorsal branches of the related posterior intercostal arteries and veins.
Lie prostrate; at the level of the lower border of spinous process of the 1st thoracic vertebra, 1.5 cun lateral toTaodaoGV13(Taodao (GV13)).
Strengthening the bones and muscles, removing obstruction in the channels and collaterals.
Hyperosteogeny of knee joint, cervical spondylosis, bone tuberculosis, arthritis, pneumonitis, bronchitis, numbness of the extremities, headache, dizziness, epilepsy, pleuritis, spasm and pain of lumbodorsal muscles.
Combined use with JingguBL64 (Jinggu (BL64) Yuan-Source Point) for treatment of impossible pronation due to stiffness of nape; with DanzhongCV17 (Danzhong (CV17) Front-Mu Point of the Pericardium), FenglongST40 (Fenglong (ST40) Luo-Connecting Point) for the treatment of bronchial asthma; with FeishuBL13 (Feishu (BL13)), TiantuCV22 (Tiantu (CV22)), ChizeLU5(Chize (LU5)He-Sea Point), WaiguanTE5 (Waiguan (TE5) Luo-Connecting Point the Eight Confluent Point), JingquLU8 (Jingqu (LU8)Jing-River Point), SanyinjiaoSP6 (Sanyinjiao (SP6)) for treatment of bronchitis.
Insert the needle horizontally 0.5-0.8 cun deep; needling response: local numbness and distension, radiating toward the shoulder sometimes; moxibustion: Using 3-7 moxa-cones, or mild moxibustion for 10 min.
Don`t puncture deeply, or else the needle would penetrate the transversospinal muscle-the external intercostal muscle-the internal intercostal muscle-the parietal pleura-the pleural cavity-the visceral pleura and the lung by its tip, and cause an injury to lung tissue, leading to pneumatothorax.
