Objectives: 1. For normal neurons, understand structure and function
... Necrosis refers to a set of morphological changes that follow cell death. The histological appearance is primarily the result of two processes: enzymic digestion of the cell and denaturation of proteins. In the brain, liquefactive necrosis often occurs (rather than coagulative necrosis in which gene ...
