where it arborizes freely; its terminal branches often show small irregular 

 projections. Lesser dendrites proceed from the sides and basal surface 

 of the pyramidal cell body. The neuraxon always arises from the basal 

 surface, and after producing branched collaterals, it generally enters the 

 white substance where it may divide in two (Fig. 446, 3). Sometimes the 

 neuraxon turns toward the molecular layer, joining the tangential fibers;
