Introduction The objective of the experiment was to name the four basic types of tissues in the human body and the major subcategories of each. Cells are the basic building blocks of life and all-inclusive functional units of unicellular organism. Group of cells that are similar in structure and function are called tissues. The four basic types of tissues are epithelium, connective, nervous, and muscle. They all have distinct features, structures, patterns, and functions. To perform specific body functions, the tissues are organized into organs such as heart, kidney, and lung. Histology is the study of tissues, complements a study of gross anatomy and provides the structural basis for a study of organ physiology. The skin is considered an organ system because of its extent and complexity. It is tough yet pliable, a characteristic that enables it to withstand constant insult from outside

Materials Microscope Histological Slides Methods The teaching assistant had the histological slides out on the table. The professor wrote down the numbers of all the important slides. We got the slides from the table. We got a microscope from the cupboard. Results Attached at the end. Discussion We identified the tissue subcategories through microscope inspection of an appropriate projected slide. We were able to list several functions of the skin, recognize, name the layers of the epidermis, and differentiate between eccrine and apocrine sweat glands. The microscopes had not been cleaned for a while so we had to take lenses off manually to clean them and observe things better....
