Relate and Review tissue Lab

In this lab I learned a lot about the different structures of the different tissues in the human body. Not just the differences between the four major tissues but I also saw the differences of different types of the same tissue. One example of this is through the different types of cartilage that we saw as well as the blood and bone. All of these are part of the same classification as connective tissue and without this lab I never really would have seen the major differences between them. I also made many connections to the things that we were taught in class to this lab. I saw the actual shape of the different types of epithelial cells and was able to see the similarities between the structures we were taught in class and what we actually observed. I also was able to observe all of the properties of cardiac and skeletal muscle cells that we learned in class through the microscope. I saw many differences between the tissue types. Muscle tissue looked very long and fibrous, contrasting much with the different types of connective tissue such as bone, blood, and cartilage. The nervous tissue also looked extremely different from the other tissues as the cells were shaped much differently and it looked more like an electrical network than a tissue composed of cells. I could see how the shapes of the muscle tissue cells help with their function. The cardiac muscle cell is branched and has the intercalated disks on the end to help keep the muscle tissue together while the heart is beating. The long tubules of the skeletal muscle tissue help for the muscle to contract and expand smoothly. I also saw how the epithelial cells function well as the skin as they are layered and designed to cover the different organs and the body.

Here are some pictures of the different tissue samples
