The highlighting is pubic symphysis.  Actually, this we have found this spot on each other many times for various exams.  Slowly walk your hand down the belly until you hit bone, done, you have found the pubic symphysis.

 And, that what I tried to do.  When I came to the bone I poked in my middle finger to show that I had found it and my partner literally jumped off the table and yelled "ouchhhhhhhhhhhh".  Several nearby tables turned to look at my terribly red face and my partner grabbing his groin.  

The day proceeded in the afternoon with another lab in which we had to make case presentations.  3 pages of information about a patient were supposed to be presented to the class.  We were allowed a 3X5 to write down certain information on one side (such as lab values and medications).  They picked people at random but it was apparent that they were picking those students that didn't talk as much in class, the shy ones.  I knew I would be called.  And I was.  I don't think that I have ever been so nervous...I have given plenty of presentations.  I have taken two college speech courses.  But for some reason, I got up there and went numb.  Every other word was "um" and I stumbled to find words such as "diagnosis", "conclusion" and "patient".  Of course, this doesn't ease my concerns for the much larger presentation that I am supposed to give in two weeks.
