Teres Minor question

[Spunk!]

OK, so I'm still (trying to find time to) studying for the NESL exam. Too much going on!

Anyway, I was taking the practice quizzes at massagenerd.com, specifically the one on back mucles actions, and the first question was

"Lateral flexion of spine" The choices are:

infraspinatus, teres minor, serratus posterior inferior, and serratus posterior superior.

It told me that the "correct" response was teres minor. I don't *think* I've seen any of the mentioned muscles acting to laterally flex the spine (though I could be wrong). I'm sure the infraspinatus doesn't. The Trail Guide book says that the Serrati "only affect movement of the ribs".

Can anyone tell me how the teres minor laterally flexes the spine, please? I am a little stumped. Everywhere I've searched has the teres minor acting on the arm and scapula, not the spine. Is the quiz wrong? If so, then how confident can I be in the rest of their quizzes?

Teres Minor question

I would only be worried if you find more errors. Try not to let one question stress you out about the validity of the entire test or other tests. On the bright side, this wrong answer made you look it up and you will not get it wrong on the exam!

If it were me, I would send a note to the site webmaster. Chances are, it was a data entry error - someone lost track of where they were and typed in the wrong answers. As you correctly noted, it wasn't a matter of the wrong answer was marked as right, none of the answers are correct.

BTW, I checked my old textbook, too - The Muscular System Manual by Dr. Joseph Muscolino.

Shannon, I'm using the Trail Guide to study. I love that book- and the workbook that goes with it too!

cicerone, you have a *solid* point about having to look it up really cementing the info in my own mind. I was telling hubby the other day that I think it was a complete error, too- as you said, NONE of the choices were remotely possible. I just may email the site admin. I really like that site, have found it helpful in many ways. Maybe *looking* for errors will help me study better! :
