I feel like I read that the Vastus lateralis is the biggest, but I could be mixing it up with another muscle.

I’m a bit confused; I thought the Vastus intermedius was deeper but not necessarily the largest.

I remember practicing a question like this, and I think it was the Rectus femoris that was mentioned as the largest.

I think the largest quad muscle is the Vastus lateralis, but I’m not completely sure.
