OBJECTIVE
To investigate the quantity and distribution of motor fiber of rat's C7 nerve root.
METHODS
Motor fiber quantity and section area in the main nerves of the upper extremity and the fascicles of C7 in 30 SD rats were analyzed.
RESULTS
Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to musculocutaneous nerve and median nerve, the orientation of these fibers were not clear. The ones (323) from posterior division were to the axillary, radial, and dorsal thoracic nerves, thus the orientation of these fascicles was relatively definite.
CONCLUSION
The distribution of the motor fibers and fascicles in the divisions of C7 in rat is similar to human beings, so rat is a relatively good model for the study of selective C7 nerve root transfer.
目的
研究大鼠C7神经根运动纤维的数量及分布情况。
方法
分析30只SD大鼠上肢主要神经及C7神经束中的运动纤维数量和横截面积。
结果
C7前支的神经束及一定数量（207条）的运动纤维分布至肌皮神经和正中神经，这些纤维的走向不清晰。后支的运动纤维（323条）分布至腋神经、桡神经和胸背神经，因此这些神经束的走向相对明确。
结论
大鼠C7各分支中运动纤维和神经束的分布与人类相似，因此大鼠是研究选择性C7神经根移位的较好模型。
