The cutaneous nerves of the head of the dog were investigated in 16 barbiturate-anesthetized dogs. The electrophysiologic demonstration of afferent impulses in a given cutaneous nerve to the movement of hairs within an area of skin was used to delineate the nerve's cutaneous area (CA) of innervation. In this manner, the CA for the cutaneous branches of the trigeminal nerve, the facial nerve, and the 2nd, 3rd, and 4th cervical nerves were determined. The CA of adjacent cutaneous nerves were found to overlap extensively. The portion of a nerve's CA which was solely innervated by it was termed the autonomous zone. Most of the CA of the head was innervated by branches of the trigeminal nerve. The internal auricular branches of the facial nerve innervated the majority of the concave surface of the pinna. The branches of the 2nd cervical nerve supplied a large CA which extended from the caudal intermandibular space to the dorsal midline and apex of the pinna. The CA of the branches of the 3rd and 4th cervical nerves occupied much of the cervical area cranial to the scapula and caudal to the hyoid apparatus. A CA was not found for the 1st cervical nerve.
在16只经巴比妥酸盐麻醉的犬中，对犬头部的皮神经进行了研究。通过电生理学方法证明，特定皮神经中传入冲动与皮肤区域内毛发运动相关，以此来划定该神经的皮肤支配区（CA）。通过这种方式，确定了三叉神经、面神经以及第2、3、4颈神经皮支的CA。发现相邻皮神经的CA广泛重叠。某条神经的CA中仅由其单独支配的部分称为自主区。头部的大部分CA由三叉神经分支支配。面神经的耳内支支配耳廓凹面的大部分区域。第2颈神经的分支供应一个大的CA，其从下颌后间隙延伸至耳廓背侧中线和顶端。第3和第4颈神经分支的CA占据了肩胛 cranial 侧和舌骨装置 caudal 侧的大部分颈部区域。未发现第1颈神经的CA。
