Digestive System Part 1

Today's Medical Topic:  Digestive System Part I - If you aren't in my A&P II class you probably won't understand this.

What Are We Looking For:   The difference between the two liver models on our practical exam.

Here is one of the "livers" on our practical.  This one has more parts than the other ones so if you are asking yourself "Which one is more complicated?"  It is this one.  This is the only one that has a right and left hepatic duct.

To remember it correctly place the model of the liver in anatomical position and then rotate it up to see the vessels and what not.  The common hepatic duct on this model is a little confusing so let's clarify.

That little whitish part is actually the common hepatic duct on this model.  It is just a matter of how far up the cut is made.

Lets take a look at the other less complicated model:

You should position and rotate this one the same way and you can see how this one is different.  So basically if it has numbers you can see on it it is the less complicated model.  163 is the cystic duct, 162 is the common hepatic duct, and 165 is the bile duct.

So thats is all I got for tonight.  Enjoy.

Teef

Today's Medical Topic:  Teef.  Otherwise known as teeth.

What Are We Looking For:   The main differentiation between different kinds of teeth and how many we have of each.

Ignoring primary dentition, your baby teeth, lets look at permanent dentition. We are sort of looking at that now.  Why sort of?  Because a full set of adult teeth has 32 teef and not 28.  These teeth seem to be missing a couple or two.

That's ok though, I think they are trying to represent an average set of adult teeth which has already had the third molars, AKA the wisdom teeth, extracted.  Very few adults in first world countries have 32 teeth after the age of 25.

Still.  A good formula for remembering teeth is:

This model only has 2 molars but it still works for the most part.  Lets go over what these teeth do.

Incisors:  Adapted for nipping or cutting off pieces of food.

Canines:  Tear and pierce food.

Bicuspids:  Grind and crush food.

Molars:  Crunch, grind, and pulverize the hardest foodstuffs.

You should take care of your teeth, they will serve you with a lifetime of eating awesome food.
