Only a couple more to go! I accomplished a perfect score on the Developmental anatomy exam, which was quickly overshadowed by what appeared to be my brain's decision to forget everything I ever knew about histology. So I did what any sane person would do and had a panic attack, made chocolate cake, and then spent the rest of the night studying. And I think I did okay. In histo I tend to get answers wrong if I don't know them for sure, but that seemed to be a much smaller portion of the exam than stuff I did know. So, yay.
Today is a study day. Physiology. The bus to school never did show up, so I had to take an alternative bus route to get within walking distance (actually, I probably could have walked in the amount of time I spent waiting for the darn thing, but that would have defeated the point of public transportation, no?). And now it's high time to study.

Kidney complexity
Today was the first day on the renal system. Our professor obviously found the subject material fascinating. The teachers get a certain light in their eyes when they talk about their favorite subject. She was able to communicate her enthusiasm, too, which not all of the professors can manage. The kidneys win as the strangest organs in the body.
The heart, which we recently started learning about in anatomy, is beautifully simple, whereas kidneys just get more complex as you go. They have teensy arteries in glorious profusion, but ordered too. Long straight branches of blood vessels that hand off tiny bunches of capillaries. Like trees. Or like an orchard, with a bundle of capillaries hanging off the branches of every tree. Then within the capillary bundles are podocytes, cells that look like centipedes stretched along the surfaces. Very, very strange.

Meltdown
It's funny, but I can now manage to have panic attacks both when I am studying and when I am not studying.
Yesterday, in histo lab, I was working my way through the slides, with that sort of emotionally neutral contentedness that accompanies good lab time. Then the student next to me started talking with the professor about how worried she was about the exam. She said she'd been looking at old exams, and the level of detail they had, and she just didn't know how she was going to manage it. She sounded pretty freaked out. And this student spends way more time studying in lab than I do. So by the time the professor had reassured her, I was starting to feel freaked out. Working through the slides only emphasized how much we have to know by next week, so studying became this battle of nerves.
Then today. I was at home on the farm and had to check on cows this morning, and I spent time with the dogs and cats too. Then there was this chest of drawers to go pick up...The ENTIRE afternoon was spent between thrift stores and the other farm, with no chance to study. As I got more stressed out at time passing, my ever-so-supportive family was sympathetic and worried--but not particularly helpful in letting me go study.
Now I've been sitting at the computer the last half hour being really stressed out, paralyzed by the prospect of trying to study tonight and still get to the scheduled events that, y'know, it would be nice to be at. Outside, the light's gone all rosy and imminent-twilightish, which is a good indication that it's time for me to log off and get around to important things.
Like, oh, studying comes to mind.

Total Expiration
The way our physiology professor describes a breathing test (like you'd do for asthma) is all in a sort of monotone voice and goes like this: "Breathe in. No, all the way, don't be wimp. Now breathe out, keep going, stop being a wimp..."
Vet school is a little like that. "Learn this, all of it, don't be a wimp, here's some more."
In the past, the thought crossed my mind that there's a lot of medicine that, to be honest, isn't that hard. I've tubed lambs and vaccinated cows, even helped set a few broken legs, and none of that was really challenging once you get the hang of it. So what in med school is worth thousands of dollars a year? What sort of information is so hard to get at, and so valuable, that only doctors have it?
The word exhaustive comes to mind. (ex. drug interactions, though that's a topic for another day)
Anatomy lab is a pretty unique thing. It's not so hard, maybe, to get a dog that died and dissected it. But it's hard to learn every muscle as you go along, and it's definitely hard to get two dozen dog cadavers together and look at all of them. But we do that. It's incredibly expensive to make the special stained slides of two hundred different tissues that we put under microscopes for histology, but every student gets a box of those for the year too. When I get home I try to tell the most interesting things I learned to whatever family or hapless friends are around, but it doesn't do it justice. There's the facts, and there's the facts that I'll remember. In undergrad, I maybe retained half of what my classes presented (hopefully the right half). In vet school, it's all important, and it just keeps adding up. Learning the muscles is like learning the alphabet: yes, you have to know all of the letters.
And in many ways, that makes it easier to learn. It has a purpose, it has a direction. I've been advised to read James Herriot once in a while, after class, to remind me what I'm going to class for. It's not to take tests. Tests are a means to an end, to learn what still needs to be learned. In the end, it comes back to the animals and the people they are important to.
Incidentally, a fun thing about being a vet student: you can walk up to random people who are out with their dog and say, "Hi, I just noticed your beautiful dog {dachsund/wolfhound/mutt). Would it be okay if I pet him? I'm a vet student!"
I mean, not that you couldn't randomly pet strangers' dogs anyway. It just gives you a really good excuse :)
One month in (almost), and some other lessons I've learned:
1. There's no such thing as eating half a donut at the morning lecture.
2. Looking at cells through a microscope is more fun than it sounds like.
3. Intervertebral disks have the prettiest cartilage. (it dyes electric blue!)
4. One hour in lab equals two hours of studying, because one hour in lab can feel like THREE hours of studying.
5. There are more parts to a bone than you ever knew.
5.a. And you have to know all of them.
5.b. Ditto for muscles.
6. Radiology is NOT nap time.
6.a. But that ten minutes between classes IS.
7. Free pizza lunch lectures don't come with dessert. Stock your locker with cookies.
8. And for my boyfriend: you know you're with a vet student when she wants to hold your hand...so she can practice identifying muscle attachments.

Scalpels are fun!
So far things are working today...I woke up, ate breakfast and rushed to class. I hold that I got there exactly on time, but realistically I was probably ten seconds late. And it was anatomy, too, which starts promptly and doesn't slow down until every last nanosecond has been eked out of the 50 minutes.
Histology doesn't have this problem. Histology, the professors just blithely keep going until they've finished whatever they're talking about, and graciously allow us to be late for lab. Since it's the lab for histology, they can do that.
Two labs today, wherein we learned that
1. As long as you are doing something interesting, like slicing away the cobwebby connective tissue (fascia) between muscles, you CAN survive a three hour lab.*
2. Histology lab is nice. It's clean, it's peaceful, you get a comfy swivel chair to sit on.
3. Your locker will smell forevermore of formaldehyde once you leave your labcoat in there.
Yesterday I learned that I officially know nothing about anatomy. I was good up until I had to identify the greater tubercle of the humerus. "The what-of-the--oh, I'm supposed to know that?" It had never occurred to me that I would be foiled by the complexity of a single bone. The darn thing has, like, a dozen parts! And it's the easy one.
It looks like, for the most part, people are done with excessive sociability. The first few days, you have to introduce yourself to everyone and try to remember horribly difficult things, like what their names are. Now that the classes are starting, we have more important things to remember. Like, when is lunch? Socializing now entails only knowing enough about your lab partners to remember which one has the bone box.
And the last new thing today: the joy of a nat across the road. Finally, reaching the place of exercise takes less time than the exercise itself. I went swimming. It was good. It wiped out the formaldehyde smell.
*EDIT: Four years later I now know I was having some major health issues at this time that made it physically challenging to stand for an hour, but their onset had been so subtle I hadn't realized when I wrote this that three hours, while not easy, was not leaving my classmates pale, weak and wondering how they were going to survive the semester. That was all the other classes.
