Lab- a/P Classification of Body Membranes
Classification of Body Membranes Laszlo Vass, Ed. D. Version 42-0010-00-01 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 What is the purpose of this exercise? ?Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.
Exercise 1: The Microscopic Structure of Cutaneous Membranes ObservatiOns Sketch your observations from the microscope slide in the lab report assistant. Indicate the keratinized layer on the sketch and describe the observed structures and cells. QuestiOns A. What is keratin? B. Why is the skin keratinized?
Exercise 2: The Microscopic Structure of Mucous Membranes ObservatiOns Draw and describe the structures you observed of the following slides: A. Pseudostratified ciliated columnar epithelium of the trachea B. Stratified squamous epithelium (non-keratinized) of the esophagus C. Simple columnar epithelium (duodenum) of the small intestine QuestiOns A. Compare and contrast the roles of the three mucous membranes. B. What is the role of mucous in the body?
Exercise 3: Observing Synovial Membrane ObservatiOns | Data Table 1: Observing Synovial Membrane |Tissue Types (epithelial/ |Membrane |connective) |Common Location |Functions |Cutaneous |Mucous | Serous |Synovial | QuestiOns A. What is the function of the synovial membrane? B. Rheumatoid arthritis results in part from an infection and immune response in the synovial membrane. What effect does this have on the ability of this membrane to carry out its functions? C. Complete Data Table 1 under observations.
Conclusion
Research pleurisy, peritonitis, and pericarditis. What are these conditions and how do they affect homeostasis in the body?
