Do you have a Palmaris Longus mucle?

While teaching my anatomy lab I like to through in a few interesting facts to keep the class listening.  An interesting fact I brought up while teaching about the flexors in the antibrachium (forearm) is that the Palmaris Longus muscle is absent in about 16% of Caucasians, usually females, and 4% of males are missing it in their left arm.  I found out that I am one of the 4%.  I wondered about the rest of my family so I want you to test yourself and take the poll.  You'll need a needle (a sewing needle works just fine), some alcohol (for disinfection), ice (to numb) and someone you trust to assist.  Just before you start take a deep breath and hold, touch the palms of  your thumb and you pinky finger together and flex your wrist slightly.  You will see the tendon of the palmaris longus stick up on your wrist very visibly, if you have one.  Now check you other hand.  It wont be hard to tell if you have one or not.  Let me know!
