But the skewer was now so close to the vertebral artery that it was bending it.

但是尖杆离椎脉太近了，使它产生了弯曲。

Most important, it had missed both the crucial arteries: the carotid and vertebral.

更重要的是，它有到两个重要的脉：脉和椎脉。

Carotid arteries supply the front of the brain, and vertebral arteries supply the back.

脉供应大脑前部，椎脉供应大脑后部。

Dr. Ebersole watched the tip of the skewer safely pass the vertebral artery. " It's sliding pretty easy now, " said Dr. Peterson.

埃伯索尔看着杆子的尖端安全地通过了椎脉处。皮特森医生说，“现在移它非常轻松”。

" Jeremy, angle it a little toward you." This would move it away from that artery. Dr. Peterson did as asked. " OK, go again." It worked.

“杰里米，把角度朝你那调整一点。”这会使它离开椎脉。皮特森医生照做了。“好的，来吧。”奏效了。
