Wait, isn't the Sternocleidomastoid also not firing?

Agreed, Levator scapula is usually inactive in that position.

I think it's definitely the Levator scapula.

No way, the Lonqus coll isn't even a real muscle!

I feel like the longus colli is often overlooked in these types of questions, but I can't remember its role in eccentric extension.

The levator scapulae seems like it might not be firing, but I could be mixing it up with another muscle.

I remember practicing a question about the anterior scalenes, but I can't recall if they fire during eccentric extension.

I think the sternocleidomastoid is definitely involved in neck movements, but I'm not sure about the others.

I've got a strategy - I'll eliminate the options I'm sure about first, then make my best guess.

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?
