Hi 8pack,
Going back to your original question Buddy, you could also check at your local library or a library that is larger and has more resources. See if they have a current anatomy atlas that shows in detail the parts of the body. There are some really good ones out there very detailed - this might be what you would want to do also.
To be sure nothing is wrong (and I have no reason to think there is at all) it does not hurt to check and be sure with a knowledgeable physician.
Also there is one site on the web I am aware of right now that might be of help:
www.webmd.com
I believe Cleveland Clinic in Cleveland, Ohio, has a website too and a phone number that you can call with questions 24 hours a day. They have Sports Medicine physicians and they take care of the medical needs of the Cleveland Browns.
Remember I do not have any reason to think you have anything wrong.
Take Care, John H.
