The anatomy of the cutaneous nerves innervating the canine thorax and abdomen was investigated by gross dissection of 38 dogs. Additionally, the cutaneous areas innervated by the thoracic and abdominal cutaneous nerves were mapped in a 2nd group of 33 barbiturate-anesthetized male dogs, using electrophysiologic techniques. The skin of the thorax was innervated by dorsal cutaneous branches, lateral cutaneous branches, and ventral cutaneous branches of the spinal nerves. The dorsal cutaneous branches were branches of the dorsal primary branches of spinal nerves C6 and T2 through T11. The lateral cutaneous branches were branches of the ventral primary branches of spinal nerves T2 through T12. The ventral cutaneous branches were branches of the ventral primary branches of spinal nerves T2 through T10. The skin of the abdomen was innervated by dorsal and lateral cutaneous branches of spinal nerves T12 through L3 (and occasionally L4). The cutaneous areas of the dorsal cutaneous branches occupied the dorsal half of the scapular and thoracic regions and the dorsal 2/5 of the abdominal region. The cutaneous areas of the lateral cutaneous branches covered the major portion of the ventral half of the thorax and the ventral 3/5 of the abdomen. The cutaneous areas of the ventral cutaneous branches occupied the axilla and the ventral part of the thoracic wall.
通过对38只犬进行大体解剖，研究了支配犬胸部和腹部的皮神经的解剖结构。此外，在第二组33只巴比妥类麻醉的雄性犬中，使用电生理技术绘制了胸腹部皮神经支配的皮肤区域。胸部皮肤由脊神经的背侧皮支、外侧皮支和腹侧皮支支配。背侧皮支是脊神经C6以及T2至T11背侧初级支的分支。外侧皮支是脊神经T2至T12腹侧初级支的分支。腹侧皮支是脊神经T2至T10腹侧初级支的分支。腹部皮肤由脊神经T12至L3（偶尔包括L4）的背侧和外侧皮支支配。背侧皮支的皮肤区域占据肩胛和胸部区域的背侧一半以及腹部区域的背侧五分之二。外侧皮支的皮肤区域覆盖胸部腹侧一半的主要部分以及腹部腹侧五分之三。腹侧皮支的皮肤区域占据腋窝和胸壁的腹侧部分。
