Brain Histology

Developing Brain Histology

Stage 22 image 217.jpg

  • Human embryo developing cortex, Week 8, Carnegie stage 22.
  • Inset (upper right) shows section overview and approximate level of section (red line).
  • Thin layer outer called cortical plate will eventually form the adult brain cortex.
    • Other underlying layers are part of the development process and will continue to supply cells to the cortex through fetal period, these layers will eventually be almost completely lost.
  • Developing cerebrum layer thicknesses are shown in microns.

Terms

  • artifact - changes and distortions introduced to the normal tissue structure by the histological processing. Common artifacts include: folds (gives the tissue a darker appearance), tears (rips in the tissue can be seen in epithelia), shrinkage when tissues loose mainly liquid through histological processing, and cuts often used in tissue preparation.
