===Cerebrum section===
The [[Forebrain_-_Anatomy_%26_Physiology|cerebrum]] contains the cell bodies of nerves both receiving and sending sensory information involved in controlling voluntary movement via motor activity and in the integration and coordination of other nerves. The cerebrum is also involved in memory functions.

In a full thickness histological image of the cerebrum it would be possible to distinguish numerous layers including the pia mater on the outer edge of the brain, the plexiform layer, pyramidal layer, granular layer and a polymorphic cell layer innermost, prior to the white matter towards the centre of the brain. The plexiform layer consists of mainly fibrous material which run in parallel to the surface of the brain. This layer contains relatively few cells, mainly neuroglial cells. The pyramidal cell layers mainly consist of small, medium and large pyramidal shaped cells which generally become larger as they become closer to the white matter of the cerebrum. Finally the pleopmorphic layer contains cells of very doverse shapes, a majority of which have a spindle shape. These cells are often called fusiform cells.
