各位老师，是这个意思吗？

Other structures in the anterior neck include the common and external carotid arteries, the external jugular veins, and the spinal accessory nerves. The common and external carotid arteries can be found below the sternocleidomastoid muscle inferiorly and then along the medial margin of the sternocleidomastoid as it divides more superiorly in the neck. The external jugular veins run superficial to the sternocleidomastoid muscle in direction from the angle of the mandible to the middle of the clavicle. The spinal accessory nerve can be found at the posterior border of the sternocleidomastoid muscle at a location midway between the angle of the mandible and the mastoid process before it travels posteriorly to the trapezius. Posteriorly, the spinous processes of the cervical vertebrae are identifiable in the midline position.

颈前的其他结构包括颈总和颈外动脉、颈外静脉和脊髓副神经。颈总动脉和颈外动脉位于胸锁乳突肌下方，在颈部向上位置分为颈总动脉和颈外动脉，沿着胸锁乳突肌的内侧缘向上走行。颈外静脉沿着下颌骨到锁骨中部的方向走行于胸锁乳突肌表面。脊髓副神经位于胸锁乳突肌的后缘，下颌角与乳突的中点，然后向后行至达斜方肌。在颈后方中线位置可以识别颈椎的棘突。

各位老师，是这个意思吗？感觉很怪，与国内说法不一样，颈总动脉沿食管、气管和喉的外侧上升，到甲状软骨上缘处分为颈内动脉和颈外动脉，既然已经分开，就不存在颈总动脉了）。谢谢
