In right rotation of the neck, which muscles are listed as antagonists?

• A. Left SCM, Left Scalenes, Left Trapezius, Left Levator Scapulae
• B. Right SCM, Right Scalenes, Right Trapezius, Left Levator Scapulae
• C. Pectoralis Major
• D. Latissimus Dorsi

Answer: (A)

When thinking about neck rotation, the muscles that oppose a turn to the right are the ones on the left side. Those left-sided muscles—sternocleidomastoid, scalene group, trapezius, and levator scapulae—are positioned to counteract or resist rightward rotation, making them the antagonists to turning the neck to the right. They can help rotate the head to the left or provide stabilization that limits rightward turning, which is why they’re identified as the antagonists in this movement. The other options include muscles like pectoralis major and latissimus dorsi, which are not primary neck rotators and don’t play a direct antagonistic role in this neck movement.
