双峰驼桡神经的解剖

Anatomy of the Radial Nerve of Bactrian Camel(Camelus bactrianus)

双峰驼桡神经起于第８颈神经、第１、２胸神经腹侧支。桡神经的肌支主要分布于臂三头肌内侧头、外侧头、长头，时肌，腕桡侧伸肌，指内侧伸肌，指外侧伸肌，指总伸肌，腕斜伸肌及尺骨外侧肌。桡神经分出的前臂外侧皮神经分布于前臂外侧面的筋膜和皮肤，分出的其余皮支分布于前臂前外侧面、腕内侧面前部、掌内侧面和第３指系关节远轴侧面的筋膜和皮肤，还分布于腕关节囊的背侧面。前臂内侧皮神经也山桡神经分出，分支分布于前臂前内侧面，掌近端半部内侧面的筋膜和皮肤。

The radial nerve in the bactrian camel derives mainly from the eighth cervicalfirst and second thoracic roots.It gives off muscular branches to innervate alI three heads ofthe triceps brachii, anconeus extensor carpi radialis,extensor digitorum lateralis,medialis com-munis extensor carpi obliquus and ulneris lateralis. The radial nerve detaches cutaneous branches to the medial aspect of the craniolateral aspect of the forearm,cranial part of themedial aspect of the carptis,medial of the metacarpus and abaxial of the fetlock of the thirddigit,and the dorsal wall of the capsule of the carpal joint.Its lateral cutaneous antebrachialnerve supplies the fascia and skin of the lateral aspect of the forearm. The radial nerve alsodetaches the medial cutaneous antebrachial nerve to ramify on the fascia and skin of the cran-iomedial aspect of the forearm and medial of the proximal half of the metacarpus.
