Tissue Lab

In this lab we (the class) analyzed and sketched different types of tissues under a microscope. We identified the tissues and drew sketches labeling specific parts and areas. We then connected our findings to our lecture notes and other readings. For example, one of the slides we looked at was a sample of ground human bone, which had very specific and defining characteristics. One thing we learned in our lecture was that skeletal muscle tissue cells are long and have a cylindrical shape with striations, or bands of fibers, and the skeletal cells we looked at reflected that precisely. I could clearly see the multiple nuclei and defining cylindrical shape and labelled them in my sketch. And then when I looked at the slide that contained a smear of human blood I could see all the red blood cells and could even make out the indentations in their center that I learned about through our specialized cell assignment. There was no visible nucleus because, as I had learned previously, red blood cells don't have nuclei. It was incredibly interesting to see that all the different tissues had all different structures and densities. Even muscle tissues were vastly varied, cardiac being much less dense and with more separation between layers while skeletal was more densely layered with more visible nuclei.
