Human Embryo Carnegie stage 22

Ventricular System

  • lateral ventricle (anterior and inferior horn)
  • interventricular foramen
  • third ventricle

Neural System

  • cortex
  • mesencephalic vesicle
  • thalamus
  • subarachnoid space

In the human embryo identify the large telencephalic vesicles and the choroid plexus. The cavity in these (the lateral ventricles) communicate with the ventricle of the diencephalon (3rd ventricle) through the interventricular foramen. The basal part of the telencephalon forms the basal ganglia, a solid mass. Posteromedially these basal ganglia are in contact with the diencephalon. The large masses in either side of the diencephalon form the thalami.
