Histology Practice Test

How Should I Use This Section?

The following study guide will help you get ready for our CNS histology test. The slides shown here are from last year, however, most of the stains will be similar. Answer each question as it is presented. Click on the letter for immediate feedback. If you make mistakes, go back and study your slides and then retake the test.

Keys to Success.

You need to know what each slide is telling you (e.g., type of cell, disease, structure, and organization). Keep in mind that later you will be examining the slides from your "unknown" subjects. So you are also trying to develop a basic understanding of what the normal brain should look like under the microscope (so that you can recognize the abnormal).

Hint. Don't forget to study the videotape of the slides that you created!!! Remember that our test will be based on slides taken from one of your boxes.


Slide #1

Identify this stain.

a.) cresyl violet
b.) Golgi stain
c.) horseradish peroxidase
d.) none of these

What is the stain in slide 1 showing you?

a) glial cells
b.)the axons of neurons
c.) the cell bodies of neurons
d.) all CNS cells in a particular region

What part of the brain is shown slide 1?

a.) rat basal ganglia
b.) sheep hippocampus
c.) sheep cerebellum
d.) rat cortex


Slide #2

 

Identify this stain.

a.) cresyl violet
b.) Golgi stain
c.) horseradish peroxidase
d.) none of these

 

What is the stain in slide 2 showing you?

a) dendrites and nerve endings
b.)the axons of neurons
c.) the cell bodies of neurons
d.) all of these

What is shown slide 2?

a.) alzheimer's dense plaques and/or neurofibrillary tangles
b.) MS scaring
c.) normal healthy cortical neurons
d.) an electrolytic lesion

Slide #3

The left image is presented at 4x and the right at 10x (+/- your screen settings). Both images show the same location on this slide.

 

Identify this stain.

a.) cresyl violet
b.) Golgi stain
c.) horseradish peroxidase
d.) none of these

What part of the brain is shown slide 3?

a.) basal ganglia
b.) hippocampus
c.) cerebellum
d.) cortex

Warining: Questions beyond this point are not finished -the answers may be wrong!

Slide #4

What is the stain in slide 4 showing you?

a) dendrites and nerve endings
b.)the axons of neurons
c.) the cell bodies of neurons
d.) all of these

What is shown slide 4?

a.) alzheimer's dense plaques and/or neurofibrillary tangles
b.) MS scaring
c.) normal healthy cortical neurons
d.) an electrolytic lesion
