Lab Report Assistant
This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
Purpose

Exercise 1: Epithelial Tissue
Data Table 1: Epithelial Tissue Observations | TISSUE TYPE | OBSERVATIONS | Simple Squamous | | Simple Cuboidal | | Simple Columnar (stomach) | | Simple Columnar (duodenum) | | Stratified Squamous (keratinized) | | Stratified Squamous (non-keratinized) | | Pseudostratified Ciliated Columnar | | Transitional | | Stratified Cuboidal (online) | | Stratified Columnar (online) | |
Questions
A. Why is the study of histology important in the overall understanding of anatomy and physiology?
B. How are epithelial tissues named?
C. Why are some epithelial tissues stratified?
D. Unlike squamous cells, cuboidal and columnar cells have large, open cytoplasm. Which functions of epithelial tissue are supported by having such big cells?
E. Look at the following drawings and identify each type of epithelial tissue:
| 1. | | 2. | | 3. | | 4. |
Exercise 2: Connective Tissue Observations
Data Table 2: Connective Tissue | Tissue | Amount and Shape ofCells | Amount ofMatrix | Are there fibers? If so,are they parallel orscattered? | Mesenchyme (online) | | | | Aerolar (online) | | | | Adipose (online) |
