Some pathology to think about.
Alzheimer’s Brain: Gross
Alzheimer’s Brain, H&E
Do you see anything different in the cytoplasm of the neurons? What might this do to them?
Normal Brain Compared to Brain from Parkinson’s Patient, H&E
Which section is from the normal brain and why do you conclude this?
Brain From Stroke Patient
Section from Brain of Stroke victim
The results of anoxia. Which cells are affected?
Brain from Infant with Tay-Sach’s Disease
What organelles in these cells are defective and how does the morphology reflect this?
Cerebrum from Patient with Creutzfeldt-Jacob Disease.
Note “holes” in cortex resulting from prion amyloid deposits. Human form of “mad cow disease: bovine spongioform encephalopathy”.
