Innies and Outies.

Well, I had intended on discussing something interesting about Embryology (i.e. the development of a baby, from conception to birth), seeing as I spent the whole day studying it in preparation for my exam tomorrow. However, most of the material I studied was sooooo dry and boring! My exam is testing me on a lot of cellular development, like what cells will make up the bones of the skull, our limbs, and the smooth muscles lining our organs (to name a few)... which isn't all that interesting nor easy to explain unless you have a strong cell biology background (or sat-in on this class!).

I did, however, find one piece of information that you may find interesting about about innies and outies (i.e. belly button types). When a baby is born, a doctor is supposed to take their two fingers and squeeze the contents of the umbilical cord towards the baby before the cord is cut. Try to imagine it as if the doctor is squeezing a tube of toothpaste towards the baby, as if to squeeze some toothpaste into the baby's stomach. The reason this is done is to drain any blood/fluid that may be in the cord, and more importantly to slide the baby's gut back into their stomach. It is possible, you see, that the gut contents of the baby may herniate (i.e. push their way into a space they shouldn't be!) into the umbilical cord. Therefore, the doctor does not want to accidentally snip their gut, so this little toothpaste-tube squeezing action is preformed. As for innies, the umbilical cord is cut to a short length and it regresses completely. With outies, the cord was not cut very short, leaving extra cord to regress and ends up leaving a little "scar" on the surface of the umbilicus (i.e. belly button).

Oh, and one more thing: did you know that (in nature) the optimal number of offspring a mother should birth is the same as the number of nipples she has? #Nipples = #Babies. So, all you human females, stop having more than two babies! Ha ha.
