testing for the presence of Pyramidalis muscle

[spozzy]

I'm in a dilemma. I'm an athletic therapy student in my second year. While in my clinical placement, my supervising therapist and a few others were on the discussion of certain muscles that only some people possess. Such as palmaris longus for example and pyramidalis. A test to see if someone has palmaris longus is to oppose your thumb to your pinky and flex your wrist. If there are two tendons present, one is the palmaris longus muscle tendon. My supervising therapist gave me an assignment. After looking through every pathological testing text and anatomy text we had, she asked me to find a test to see if someone had a pyramidalis muscle without having an MRI or dissecting someone. After a couple weeks of searching through several more text books, scowering medical journals, asking some of my professors and searching the internet, i have turned up nothing. My anatomy professor, who has been teaching the class for a long time, said she did not think there was one as she has never heard of any ways. So i am trying to broaden my resources and am asking if anyone here has any idea where i could find a test or if anyone knows of any that could help me. Thank you in advance for any input.
