Fig. 1. Semi-diagrammatic representation of a transverse vertical section of the 

 infundibular region of the brain, at the opening of the cavity of the ventricle into the 

 lumen of the infundibulum. o lumen of ventricle; a lumen of the infundibulum. 

 1 Primary forms of ependymal neuroglia, the processes extending from a cell-like body 

 at the edge of the ventricular cavity, to the sub-pial limit. 2 Coarser and less ramified 

 variety of ependymal cell. 3 Coarse ependymal cells, branching within the inner half of 

 the infundibular wall. 4 Portions of ependymal cells with tufted sub-pial branches. 

 5 Burr-like cells of the inner half of the infundibular wall. 6 Long rayed ependymal 

 cells at the juncture of ventricular and infundibular cavities. 7 Fir-tree ependymal cells, 

 of various sizes and forms, lining the border of the ventricle. A few are seen to end 

 with ball-like knobs against the pial limit of the basis cerebri. 8 A dislocated ependymal 

 cell of the same type. 9 Neuroglia cell approximating the short rayed type of Golgi. 

 10 Sustentacular glia cells of the inferior border of the tuber cinereum. 11 Very large
