This morning we actually had lab instead of lecture. Usually it's the other way around. We learned about the nervous system, which means we got to see shark brains! Score!

Sebastian, yet again, was the best. He was a little hard-headed at first, you know with all that cartilage around the brain, but it didn't take too long to cut through it. I know you want pictures. 

Voila! A brain! It may be small, but it's effective! That big white mass closer to the eyes is the cerebellum, which is responsible for voluntary muscle movement. There are actually 2 branches that extend into the sides of the snout that you can't really see in this picture. Those extensions aid in the shark's sense of smell. It's really cool. At least I think it's cool...

We also had to cut out...get ready for grossness overload...the eye. Yes, a shark eye. It was quite difficult to do. I won't show you nasty pictures of the eye ball (it's not like I haven't shown you anything nasty so far anyways), but we did dissect the lens out. 

That little ball laying by Sebastian's head is his lens! It looks like a little plastic ball. And it feels like plastic, too! Seriously, it's hard as a rock. Like we could play miniature baseball with it. (We may or may not have attempted that.) It was crazy. Today was a good lab.

I know every single one of you enjoys the glamorous Sebastian photos. I'm just one of those obnoxious mothers who puts pictures of her kid online. Except of her kid's dissection...don't judge.
