Introduction: There are two major categories that body membranes that cover surfaces, line body cavities and form protective sheets around the organs are epithelial and synovial membranes. Epithelial membranes form one of three common varieties the cutaneous, mucous or serous. In the skin, a dry membrane with a keratinizing epithelium is the cutaneous membrane. Mucous membranes are composed of epithelial cells resting on a layer of loose connective tissue. Finally, the serous membranes are made of simple squamous epithelium on a scant amount of arelar connective tissue. The framework of the body is known as the skeleton. It is made up of two of the most supportive tissues found in the body, which are cartilage and bone. Two basic kinds of osseous tissues are compact and spongy bone. Compact bones are smooth and homogeneous. Spongy bones are small trabeculae of bone and lots of open space. Materials Microscope

Unformatted text preview: • Prepared slides • Articulated skeleton Methods In exercise 8 you need look at prepared slides of the mucous structure. Identify the epithelial types and also look for the goblet cells. Then, we looked at the synovial membrane. In exercise 9 look at the long bone and identify the diaphysis and periosteum. View the epiphysis and notice the thin layer of compact bone that has spongy bone. Identify the articular cartilage and the epiphyseal plate. Finally look at a prepared slide of ground bone and view it on low power. Look at the osteocytes in lacunae that are around the concentric circles. Conclusion: In conclusion this lab teaches you what the different epithelial types. The mucous, serous and cutaneous membranes look like. It also taught me how to identify the different bone structures and the compact and spongy bones. Reference: • Human Anatomy and Physiology laboratory Manual....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
