Comparative mapping of peripheral nerves in dogs and cattle

ABSTRACT Knowledge of animal anatomy is essential for the veterinarian to identify small structures such as nerves, thus providing a solid background for the professional especially for surgical and anesthetic techniques. To investigate and map the nerves of the brachial plexus (radial, musculocutaneous, ulnar, median), sciatic, tibial, femoral and the nerves for paravertebral blocking in bovine, embalmed specimens were used. One adult male dog weighing approximately 8kg and one 40kg male calf were used. Nerve mapping is fundamental due to its interdisciplinary nature, thus providing the veterinarian with a major improvement in his/her professional activities which permits allows one to perform complex tasks in anesthesia and veterinary surgery. Knowledge ofanatomical reference points increases clarity and precision in techniques involving peripheral nerve blocks.

摘要：动物解剖学知识是兽医识别神经等微小结构的必要基础，可为从业者尤其是外科与麻醉操作提供坚实的理论支撑。为研究并绘制牛臂丛神经（brachial plexus）的桡神经、肌皮神经、尺神经、正中神经，以及坐骨神经、胫神经、股神经和椎旁阻滞（paravertebral blocking）相关神经的解剖分布图谱，本研究采用防腐标本（embalmed specimens）开展实验。实验所用标本包括1只体重约8kg的成年雄性家犬，以及1只体重40kg的雄性犊牛。神经解剖图谱的绘制兼具跨学科属性，属于基础性研究工作，可显著提升兽医的临床执业能力，使其能够顺利开展麻醉与兽医外科领域的复杂操作。掌握解剖学参考点位，可有效提高外周神经阻滞（peripheral nerve blocks）操作的清晰度与精准度。
