Histology Lab
Purpose: To review the characteristics of epithelial, connective, muscle and nervous
tissues and to observe examples.
Objectives:
1. Describe the characteristics and types of epithelial, connective, muscle and
nervous tissues
2. Indicate a location and function of each type of tissue
3. Identify examples of epithelial, connective, muscle and nervous tissues
Materials:
Textbook or notes
Microscope
Prepared slides of tissues
Colored pencils
Procedure:
1. Use the microscope to observe the prepared slides of the different types of
tissues.
a. Look for its special distinguishing features: such as cell size, shape and
arrangement.
b. Compare the prepared slides to the pictures in the text and/or your notes.
2. Sketch a FEW of the cells of each type of tissue in part B of the lab report. For
each sketch, indicate magnification, and include a location example and the
function of the tissue.
3. LABEL THE MAJOR CHARACTERISTICS OR STRUCTURES THAT YOU
USED TO IDENTIFY THIS TISSUE.
4. Use colored pencils to differentiate various cellular structures in your sketches.
Select a different color for each of the structures on the color key and color those
structures as seen in each of your sketches.
5. Test your ability to recognize each type of tissue. To do this, have your lab
partner select one of the slides, cover its label and focus the microscope on the
tissue. See if you can correctly identify the tissue.

Saugus High School Lab Conclusion
Write the following conclusion following the Science Writing Guidelines. Use complex
sentences in all sections.
1. Introductory statement with the purpose or the problem and hypothesis.
2. Summary of experiment with results. (This is slightly different from the standard
conclusion for this lab).
 Describe the four tissue categories present in the body and the characteristics
that are common with that tissue.

Using ONE example from EACH tissue type, explain how the cells and
components of the tissue exemplify the characteristics of that particular tissue
type.
EPITHELIUM
CONNECTIVE
MUSCLE
NERVOUS
3. Describe any real or possible error. If you had real error, explain why this error
occurred. If no error occurred, explain why another group had error or theorize where
error could occur. Be specific and do not describe a math error--instead re-do the math.
4. Paraphrase and cite the textbook or other reference material (using MLA format) and
explain whether the results of this lab confirm or refute the scientific concepts in the
material.
5. Provide a concluding statement that is evidence-based (facts and data). Remember,
no opinions or feelings.
