Histology Slides for the Epithelial, Connective, and Integumentary Tissues Slides are presented in order of magnification As you view the following slides make sure you can accomplish these goals: 1.Can you identify the tissue layers observable on the slides? 2.Can you identify the specific structures or layers indicated by the numbered arrows or brackets? At the end of a sequence you will find the answers to the above for each vessel and layer.

Answers to Slides 3-9 Slide 3: Surface view of simple Squamous epithelial Cells designed to cover surfaces, have large surface area on surface plane and are thin in side view. Slide 4: Smooth muscle cells Cell spindle-shaped to contract and elongate on a single plane Slide 5: Red blood cellswith a few white blood cells Biconcave to increase surface area to volume for diffusion and non-nucleated to increase hemoglobin capacity. Slide 6: Human sperm cells Small flagellated cells for swimming. Small size to increase the number of cells that can be placed in a small amount of solution Slide 7-9: Mitosis of a fish egg 1.
