In neck extension, which muscles act as antagonists?

Explanation:
When you extend the neck, the opposing muscles are the neck flexors. The sternocleidomastoid and the scalene muscles are the primary neck flexors; they bring the chin toward the chest and assist with sideways bending. In the act of extension, these muscles would lengthen and, if activated, counter the motion, providing control and opposition. The other listed muscles aren’t the main antagonists to neck extension—they’re more involved with shoulder girdle or trunk movements and don’t directly oppose neck extension in the same way.
