In this lab we were only observing slides of tissues under microscopes. My partner and I observed three samples of epithelial tissue, three samples of connective tissue, three samples of muscle tissue, and two samples of nerve tissue. We sketched all of the observed samples and labeled what they were.
These are sketches of epithelial tissues from mammals. They looked a lot cooler under the microscope. There were lots of little cells to focus on.
The connective tissues were also a lot of fun to look at. These are all mammalian samples as well. It's really neat to see the cells separated from each other in their lacunas or just separated by the matrix they're in.
The muscle samples had a lot more smooth places than connective tissue and epithelial tissue because of their fibers. These are also mammalian samples.
I did not like looking at nervous tissue samples and I did not like drawing them either. They were too smooth, too unbroken! It was like fresh snow and just begged for a few cells to go plant themselves in the middle of the sample to be interesting.
I've already written extensively about connective tissue and epithelial tissue but I've never really talked about muscle or nerve tissues before. There's really not much to say. Muscle and nerve tissues get kind of boring under a microscope because there's more fibers than cells to look at, more smooth than speckled.
I love microscope labs. It's a lot of fun to look at things really close up and see what things really look like, to watch pink smears become landscapes of cells and nuclei. I hope we do a lot more microscope things in this class. I'm really good at adjusting microscopes and I hope Mr. Ludwig will let us make our own slide samples when we do dissections. (Hint, hint, nudge, nudge. I know you're reading this.)
