Molecules, Cells, and Tissues Review Material

The Practical Exam for Molecules, Cells, and Tissues will be Friday, September 18th. The practical exam will cover all slide material presented thus far.

Listed below are several different tools available for individual or small group review. We do NOT want to overwhelm you, so please just use the items that are helpful for your review for the Practical Exam. We suggest that a good review exercise is to try to identify unknown cells and tissue from the resources listed below while writing down the key structural characteristics of each cell or tissue. Working with a colleague can be helpful. Ask your instructor for help if you have trouble with identifications.

Review Material

(1) Molecules & Cells Brief Review of Lab Material: This document lists all of the cells and tissue we've covered thus far and briefly describes the key features that may be used to identify them.

(2) Review Powerpoints and other materials: Many lab instructors have prepared study notes, reviews, or orientation images for each lab, all of which can be found on BlueDocs in each lab slot. For your convenience, they have also been collated into the drop-down menus below:

Suggested Slides for Review (with tissues they display):

Webslide 0012_A:  Monkey Ear
[Aperio ImageScope] [Aperio WebScope]

• stratified squamous epithelium keratinized
• cartilage
• dense irregular CT (under epithelium)
• nerve
• adipose tissue (unilocular)
• endothelium (simple squamous epithelium lining blood vessels)
• striated muscle

Webslide 0065_G: Thick Skin

• fatty CT
• vasculature with smooth muscle, simple squamous epithelium

Webslide 0054_G: Gastro-Esophogeal Junction
[Aperio ImageScope] [Aperio WebScope]

• simple columnar epithelium
• stratified squamous epithelium, non-keratinized
• smooth muscle
• both loose (cellular) CT and dense irregular CT

Webslide 0301_A: Fetal Finger
[Aperio ImageScope] [Aperio WebScope]

• stratified squamous epithelium keratinized

UMich Slide 265: Nipple, Human, H&E
[Aperio ImageScope] [Aperio WebScope]

• stratified squamous keratinized epithelium
• stratified cuboidal epithelium (ducts and sebaceous glands)
• smooth muscle
• dense irregular connective tissue

UMich slide 250-1: Vagina, Human, H&E
[Aperio ImageScope] [Aperio WebScope]

• dense irregular connective tissue
• smooth muscle
• adipose tissue
• nerve
• parasympathetic ganglia

UMich slide 250-2: Vagina, Human, Masson trichrome

Same as slide 250-1 above, but this slide is stained with trichrome in which connective tissue and nerve stain BLUE; muscle and epithelia stain RED 

Example of Possible Exam Format:

Some students wonder about the format of the final exam.  The following illustrates a method that we have used in the past, where we label several tissues or cells (“A”, “B”, “C”, etc.) on a webslide of an organ.  Using the virtual microscope, the student examines the section and is then asked to identify, describe, and sometimes draw a picture of each tissue or cell.  (The student is NOT required to identify the organ, which we will cover in the Normal Body course.)

For items A through H labeled on the slide (see below for an orientation image), identify the predominant tissue type for each label in the image, listing key structural features.  For each tissue, provide a drawing labeling the key cell types.  Be sure to include a scale marker.
