Unit 1 Reflection

This unit was about the four main types of tissue, specifically their function and structure. We also learned about the anatomical positions and the four macromolecules. The themes of this unit were how form fits function, and how all the different functions work together to serve a specific purpose in the human body. I think one of the key essential understandings was to be able to describe and locate any point on the body, as well as understand the main components of the human body, which include epithelia, connective tissue, muscle, and nervous tissue. I learned a lot about these different cells, specifically epithelial and connective tissues, as well as the structure of smooth and skeletal muscles. I did not know that skeletal muscles were multinucleate, and another interesting thing I learned was that epithelial cells are continuous sheets and not only serve as protection, but are also responsible for absorption, secretion, filtration, and forming slippery surfaces. I still do not fully understand the functions of neuroglial cells and also why bones and blood cells count as connective tissue. Next unit, I will improve by studying for the test earlier, and also writing neater if I can so that my notes are easier to read. One real world connection is a pathologist. If someone were to be a pathologist, his understanding and fluency of the anatomical positions would be crucial because he would have to describe where various injuries are on a human body. He would also need to know all the major components of the human body, and how the injuries could have affected the organs or other body parts to cause death. If the pathologist did not have a good understanding on the human body, then there is no way that he would be able to do his job with accuracy and reliability. Even if someone doesn't become a pathologist, knowing the anatomical positions is especially useful because if you or someone else is injured, then you need to describe the anatomical position of the injury to an EMS personnel over the phone.
