Smooth muscle develops from which of the following germ layers?

(A) Endoderm
(B) Mesoderm
(C) Ectoderm

They say it's B because of the muscloskeletal and circulatory system...but doesn't the muscle system have skeletal muscles? I thought endoderm produced smooth muscle as well...

Of the three types of muscles (skeletal, smooth, and cardiac), two of them -- skeletal and smooth -- are part of the musculoskeletal system.

Yea, I've been stumped by this too...haha

Yes, it seems Kaplan must have made a mistake on this one...considering both layers contain smooth muscle.

This is clearly a mistake...
