Histology Lab - the Study of 4 Tissues (Plus Mitosis)
Epithelial Tissue: Fill in all boxes that aren't crossed out with drawings of the tissues. Label each with a body part the tissue can be found in. Do the generic drawings of the categories ("Squamous" box, etc.) in the 1st row and 1st column from Chapter 4 in your book.

1. What do the columns describe?
2. What do the rows describe?
3. What is a lumen? Why is it important when looking at epithelium tissue?
4. What is a basement membrane?
5. Label the cilia on your pseudostratified columnar drawing.
6. Also draw Transitional Epithelium tissue (urinary bladder). What is special about this type of epithelia-why doesn't it fit into one of the boxes on the chart?
Connective Tissue
Draw the tissues from the slides on the link and label a body part the tissue is found in.
There are 2 types of "true" connective tissue-Loose Fibrous& Dense Fibrous:
|
Areolar (loose)
|
Reticular (loose)
|
Adipose (loose)
|
|
|
|
|
|
Dense Regular
|
Dense Irregular
|
Elastic Tissue (Dense Elastic)
|

7. Label any fibroblasts and any collagen or elastic fibers you see on the loose and dense connective tissue. Label the adipocytes on the adipose tissue.
8. What is stored in adipocytes?
Draw three other types of Connective Tissue (also Lymph is considered a Connective Tissue):
9. What are lacunae and which two types of connective tissue have them? Label any you see.
10. Label the osteon or osteocyte cells of the bone tissue.
11. On the blood slide, draw and label Red Blood Cells (pink and plentiful), White Blood Cells (larger and purple), and any platelets you see.
Muscle Tissue
Draw the three types of muscle tissue and label a body part it comes from.
12. Which types of muscle tissue are striated (light striping)? Label on your drawings.
13. Which types of muscle are voluntary and which are involuntary?
14. Label nuclei on your drawings.
15. Which type of muscle has intercalated disks? Label on your drawing.
Nerve Tissue
16. Which slide should you be looking at as the example of nerve tissue (nerves conduct signals to/from the brain and _________________)?-hint: look at the "smear" slide.
17. Draw the nervous tissue and label a neuron cell with its nucleus, dendrites, cell body, and axon.
Mitosis - Cell Division
18. Often a slide of an onion root tip is used to easily see cells undergoing the stages of mitosis-why would that be a good place to find cell undergoing mitosis?
19. Draw and label the 4 stages of Mitosis(put in the correct order of occurrence) from the Whitefish slides on the link: Anaphase, Metaphase, Prophase, Telophase. (Interphase is not technically considered one of the stages of mitosis-it is the cell preparing for mitosis).
