The cutaneous innervation of the thoracic limb was investigated in 18 barbiturate-anesthetized horses, using electrophysiologic techniques. The cutaneous area (CA) innervated by each cutaneous nerve was delineated in at least 4 horses by stroking the hairs with a small watercolor brush while recording from the nerve. Mapping of adjacent CA revealed areas of considerable overlap. The part of a CA of a given nerve supplied only by that nerve is referred to as its autonomous zone (AZ). In contrast to the standard textbook illustrations cutaneous branches of the axillary, radial, musculocutaneous, and ulnar nerves overlapped extensively in the antebrachium. Clinically testable AZ were found in the antebrachium for the caudal cutaneous antebrachial nerve of the ulnar nerve and in the carpus and manus for the cutaneous branches of the median, ulnar, and musculocutaneous nerves; AZ were not found for the cutaneous branches of the radial and axillary nerves.
采用电生理技术，对18匹巴比妥类麻醉马的胸肢皮肤神经支配进行了研究。通过用小水彩刷轻拂毛发并记录神经活动，在至少4匹马中描绘出每条皮神经支配的皮肤区域（CA）。相邻CA的映射显示出相当大的重叠区域。特定神经的CA中仅由该神经供应的部分称为其自主区（AZ）。与标准教科书插图不同，腋神经、桡神经、肌皮神经和尺神经的皮支在前臂广泛重叠。在尺神经的前臂后皮神经的前臂中以及正中神经、尺神经和肌皮神经的皮支在腕部和手部发现了临床可测试的AZ；桡神经和腋神经的皮支未发现AZ。
