In this study, we dissected and measured both sets of intercostal nerves including lengths, diameters, and axon counts in 12 adult rats to provide data applicable to experimental nerve graft research. Dissections showed that total lengths of intercostal nerves from the spinal bifurcation to their last arborizations near the midline ranged from 10 to 89 mm, and diameters ranged from less than 0.1 to 0.5 mm from the thinnest to the thickest part. The segment of easiest dissection was the part between the spinal bifurcation and the lateral cutaneous branch. This part was 4-27 mm (mean, 13.3 mm) long and had an almost constant diameter of 0.18-0.5 mm (mean, 0.32 mm). Counts ranged from 201 to 566 axons/ nerve. The segment proximal to the lateral cutaneous branch was the most convenient part to be harvested as a nerve graft, especially in the 8th to 12th intercostal nerves. These nerves could serve as sources for experimental grafts.
在本研究中，我们解剖并测量了12只成年大鼠的两组肋间神经，包括其长度、直径和轴突数量，以提供适用于实验性神经移植研究的数据。解剖显示，肋间神经从脊髓分叉处到其在中线附近的最后分支的总长度为10至89毫米，直径从最细处的小于0.1毫米到最粗处的0.5毫米不等。最容易解剖的部分是脊髓分叉处与外侧皮支之间的部分。该部分长4 - 27毫米（平均13.3毫米），直径几乎恒定，为0.18 - 0.5毫米（平均0.32毫米）。轴突数量为每根神经201至566个。外侧皮支近端的部分是作为神经移植物采集的最方便部位，尤其是在第8至12肋间神经。这些神经可作为实验性移植物的来源。
