Objective Through dissection of the thoracodorsal nerve in 22 adult male corpses,to measure the length of thoracodorsal nerve and the length of displaced nerve need respectively in order to provide possible anatomical basis for treatment of deltoid muscle and axillary nerve.

Objective To discuss the significance of predicting the injury degree of the thoracodorsal nerve by intraoperative electrophysiological examination in the C7 nerve root transfer for brachial plexus injury patients.

Objective To assess the pectoralis major muscle function after modified radical mastectomy by muscle strength,ultrasonogram and electromyogram,and also with an evaluation of the significance of preservation of the anterior thoracic nerve.

Morphological Observation of Thoracic nerve root sheath and its Clinical Significance;

(3) Rectus abdominis was supplied segmentally and overlapped by anterior branches of the 7th to 12th thoracic nerves and the first lumbar nerve.

In the histological studies, the thoracic ganglion mass of Scylla serrata is fused from the sub esophageal ganglion, the thoracic ganglion and the abdominal ganglion.
