tissues
Find a slide with an example of each tissue listed below. Ideally, use a virtual microscope website and scroll around to find a good area to draw. Also, use reputable sites online to find pictures (with magnifications). Make sure what you see in the microscope is the correct part of the tissue before you draw. Confirm with Van De Graff, OpenStax or another reputable source before you draw. (Simple Google searches can steer you wrong! In class, students often draw the first thing they see on the slide. Some tissues are less obvious, and I can’t look over your shoulder to help you.) When you find the correct tissue, draw what you see in the field of view (large enough to show detail and fill the circle on the template
Actions).
For full credit (6 pts per tissue): Label the area containing the appropriate cell type. Include approximate total magnification used (probably fairly high to show details in lab I would recommend drawing at 400x) and an example tissue where this cell type can be found. Make sure there are at least two labels on each picture (you’re welcome to put more to help you study). Also include why this tissue is useful in the body (its function, ex: allows diffusion, fills spaces, etc).
I do not expect perfect artistry, but maximal detail (and appropriate labels) will help you study for your tissue exam ( on June 4, when this book will be submitted). You may use the example provided in this module or draw your own. You may draw on paper or digitally. (However, keep the drawings about 3-4″³ diameter to maximize detail). In class, you would have time to work on your drawings throughout the quarter, so I do not want you to try to finish this this week. In lab I’d recommend doing only 1-3 pictures at a time (some students find it a nice distraction from memorizing things).
The list to draw:
Epithelial
Simple squamous epithelium
Simple cuboidal epithelium
Simple columnar epithelium
Stratified squamous epithelium
Pseudostratified, ciliated columnar epithelium
Transitional
Connective
Dense regular connective tissue
Dense irregular connective tissue
Adipose
Hyaline cartilage
Fibrocartilage
Elastic cartilage
Blood (notice the ratio of cell types)
Bone COMPACT will be on the test, but you will get credit for compact or spongy, you only need to draw one
Muscles
Skeletal muscle
Cardiac muscle
Smooth muscle
Nervous
Neuron
Nerve fascicle (often a combo slide: “nerve/artery/vein”)
