I made a noodle bowl for lunch today. EVEN THOUGH I was very aware that I needed to dump the water out very carefully, forces were working against me. The steam burned my hand, my hand jerked away from the bowl, the lid fell off and my noodles ended up in the kitchen sink. Sigh.
But, I decided to use this as an object lesson to help me study for my test on the nervous system tomorrow. Let's see...so me jerking my hand away from the sensation of pain shows my Class A Fibers in action. Class A Fibers, not to be confused with Class B or C Fibers, have the largest diameter of neuron fibers and are fully myelinated. Being fully myelinated helps increase the speed with which these fibers can detect and then relay stimuli to the brain. You can find Class A Fibers in both sensory and motor nerves. And, if I have it right, the sensory A fibers were the ones that said to my brain, via my spinal cord, "Ouch! That's hot. We should do something about that." Then, my motor A fibers told my skeletal muscles, "Hey dummy! That's hot. Move your hand." Or something like that.
Just in case you wanted to know.

Things that make you go hmmmmm...
So if you're a regular reader of my blog, you may have noticed that I have slacked off a bit in the posting department, both in quantity (and maybe quality) and length of posts. Things have gotten really busy lately with school coming to a close for the semester (4 tests in 2 weeks, how much fun is that?) but that's not the only reason.
I was talking to a friend the other night about blogging and why I do it and this popped out: "I find it easier to blog when I'm sad or upset. It's my outlet when I need to let stuff out." I think everyone could agree with me on that. But are we getting the "meta-message" here? I hope so.
The realization made me, well, happy.

YAY FOR GIRLS!
I just have to say, I love my girls! It's been a long time since I've really felt like I had girlfriends, and now I have so many. It's great to know you always have someone to talk to or someone to do something with if you need distraction, a laugh, or a hand.
Speaking of, better go consult on outfit choices for the night! What's more fun that that?

This is the fun part - when anything (or nothing) could happen.

What a weekend!
Don't you hate when the weekend's over and it feels like you didn't even have one? That was mine this weekend. Pretty much every hour was scheduled (with fun stuff, but still). I hate that. I need some lay around and do nothing time each weekend. Now I've got 5 days until my next chance at relaxation. Poo.
