But during eccentric extension, the Levator scapula is actually firing to control the movement.

Ha, I bet the answer is A) Sternocleidomastoid. That muscle's busy turning my head, not extending it!

Hold up, is this a trick question? I'm gonna go with C) Anterior scalenes. Those bad boys are all about keeping the neck upright.

I'm pretty sure it's B) Longus colli. That muscle's all about flexion, not extension, right?

Hmm, this one's a head-scratcher. I'm going to guess D) Levator scapula. Seems like the odd one out for eccentric neck extension.
