Human anatomy: name of muscles at the back of the thigh

Is there a common term? I know they all have specific names for medical types, but is there a term to that muscle group, similar to “quadriceps” for some of the muscles at the front of the thigh?

Hamstrings.

I was thinking of the sartorius muscles.

The sartorius is the one that pulls your legs into a cross legged posture, “sitting like a tailor.”

Ding!

And lest I appear ungrateful, thanks!
