Cerebral cortex                                    Chart

      
Cell types: Neuron - pyramidal cell, oligodendrocyte, astrocyte, microglia, ependymal cell
 

Differential diagnosis:
Other nervous tissues such as the peripheral nerve have holes which are characteristic and the cerebral cortex does not have H-shaped grey matter with a central canal as in spinal cord. Cerebral cortex has characteristic pyramdial cells with triangular shaped pericaryon.

 Roll over mouse

Diagnostic Features:
a. Tissue is compact (e.g. liver) and there is no lumen visible. It consists mainly of neuronal cells with prominent axons (nerve fibers).
b. Pyramidal cells are visible in the cytarchitecture of the cerebral cortex as darkly stained multipolar neurons with triangular shaped pericaryon (cell body).

Database selection: Practical Tissue Gross

Level 1: Select  compact
Level 2: Select nervous tissue from list of sclerous, muscular, connective, organ-glands and nervous tissues. Tissue has visible fibers (axons) and the relative homogeneity of nervous sections.
Level 3: Select cerebellar cortex in view of multipolar pyramidal cells with triangular shaped pericaryons.

Note cytoarchitectonic laminae in cerebellar cortex (3 layers).
