Need a Tissue?

Today we looked at many different types of tissues through a microscope so we got to see what they actually look like. The different type of epithelial cells we looked at were: stratified columnar, lung lining, ciliated columnar, and human skin. Even though all of these are linings, they all looked very unique.
The stratifies columnar that we looked at was a type that is found in the urethra and some glands, but my partner and I both agreed it most likely came form the urethra. The lung lining looked very stringy and was stratified squamous so it had many layers to it. The ciliated columnar was very interesting to look at because cells made the tissue look like a feather. The human skin cells that we looked at were as one would expect skin tissue to look like, the squamous cells on top and a think connective tissue layer underneath. 
We also looked at a few types of connective which also looked very unique to one another. The different types we looked at were two kinds of cartilage and bone. The different types of cartilage we looked at reflected what purpose they had; the ear cartilage looked solid but pliable and the developing looked incomplete like it was growing. The bone was the coolest to look at because it reminded me of a spider web. The bone had circular growth which is most likely a result of building strong supports.
The only type of nervous tissue we looked at was one that we identified as peripheral nerves at the intersection of nerve fibers.
We looked at all three types of muscle tissues: skeletal, cardiac, and smooth. The cardiac and skeletal both had striations while the smooth did not. These types of tissues help move the body and move blood and nutrition around.
