Question of the Day
There is a foramen ovale in the human heart that is used to shunt blood from the right atrium to the left atrium in the fetus. Where is the location of the other foramen ovale and what is it used for?

Well, first you gotta get outta the left atrium, into the left ventricle, out the aorta, go up the common carotid (right, left, don' make no diff)and up into the skull. Then you cruise around until you find the spina angularis. (Naturally, you stop for just a sec to reminisce about how the spina angularis is an attachment point for the sphenomandibular libament and the Tensor veli palatini.) If you look straight ahead (like, anteriorly) and slightly medial, you will find the foramen ovale. It is really cool. It is a passage for the mandibular nerve, the accessory miningeal artery and sometimes the lesser petrosal nerve. Its home of record is the sphenoid bone of the skull. Wow!!!
OK, my guess is the leg? Probably wrong mind you but I have no idea. That's why my brother is at med school and I'm an accountant. Hey Jim- I can bill them for your time.
Oh, there are 7 children in Sound of Music.
