Brain.. Molecular or epileptic stratum. External granularity. External hierarchy. Internal granularity. Internal hierarchy. The polymorphic layer

Cerebrum:
It is also composed of inner core and outer shell. The crust is made up of six layers, but the boundary between the layers is unclear. The distinction of these layers is based on the predominant type of cells, which are as follows:
1. Molecular or plexiform layer
It consists of nerve fibers parallel to the surface. The deep part consists of cells called Cajal's cells.
2 - granular layer outer granular layer
Contains small pyramidal cells.
3 - the outer layer of the outer layer pyramid layer
Containing neuronal cells of medium size larger than the cells of the previous layer.
4. Inner granular layer Inner granular layer
It is characterized by the presence of many small and stellar neurons.
5 - the inner pyramid class Inner pyramidal layer
Contains large pyramidal cells.
6. Polymorphous or multiform layer
This layer contains many forms of cells and many of these cells have spindles and also contain many nerve fibers. Under this layer is the white matter, which forms the pulp.
