method). Low magnification.

FIGURE 9.12 | Layer V of Cerebral Cortex

A higher magnification of layer V of the cerebral cortex illustrates the large

pyramidal cells (3). Note the l large vesicular nucleus (3) with its nucleolus (3).
The silver stain also shows numerous neurofibrils (9) in the pyramidal cells (3).
The most prominent cell processes are the apical dendrites (1, 7) of the
pyramidal cells (3), which are directed toward the surface of the cortex. The

axons (4, 10) of the pyramidal cells (3) arise from the base of the cell body and
pass into the white matter (see Fig. 9.11 [10]).

The intercellular area is occupied by neuroglial cells (2, 8) in the cortex,
small astrocytes, and blood vessels—venule (5) and capillary (6).

FIGURE 9.13 | Cerebellum (Transverse Section)

The cerebellar cortex (1, 10) exhibits numerous deeply convoluted folds called
cerebellar folia (6) (singular: folium) separated by sulci (9). The cerebellar folia
(6) are covered by the thin connective tissue, the pia mater (7), which follows the
surface of each folium (6) into the adjacent sulci (9). The detachment of the pia
mater (7) from the cerebellar cortex (1, 10) is an artifact caused by tissue

fixation and preparation.
