一侧夹肌收缩使头转向对侧？

The posterior muscles of the neck include the splenius muscles. The splenius muscles, which are innervated by dorsal rami of inferior cervical nerves, consist of the cranial and cervical portion known as the splenius capitis and splenius cervicis, respectively. These muscles originate from the nuchal ligament and spinous processes of C7–T6 and travel superolaterally to insert on the superior nuchal line of the occipital bone, the mastoid process of the temporal bone, and the transverse processes of C1–C4. When unilaterally engaged, these muscles laterally flex and rotate the head to the contralateral side. When bilaterally engaged they extend the head and neck.

颈后肌包括夹肌，由头部（头夹肌）和颈部（颈夹肌）组成，为颈神经后支所支配。夹肌起源于C7～T6的项韧带和棘突，向上外侧走行，止于枕骨的上项线、颞骨乳突和C1～C4的横突。当单侧收缩时，肌肉侧曲并将头部转到对侧；双侧收缩时，可后仰头颈部。

理解的对吗？

可是国内的书都是：一侧夹 肌收缩 使头转向同侧
