The student will identify the following from the microscope and skin model:
Three layers of the integument:

When asked to identify the type tissue, the student must include epithelial tissue (epithelium) or
connective tissue with the type tissue. Example: Simple squamous epithelial tissue or simple squamous
epithelium, and dense regular connective tissue are correct; whereas, simple squamous or dense regular
are incorrect.
