CEREBELLUM – 3
In the smaller figure, the rectangle indicates a small region of a cerebellar fold, that will be analyzed in the larger figure. The larger image shows half of a fold.
Initially, observe the white matter in the lower region of the image, which forms the axis of the fold indicated in the smaller image.
These are the three thin, pink bands inside the organ. One of these bands is under the lower bar of the drawn square.
The white matter is highlighted in white when you hover the cursor over or click on the lower image. Note in the larger figure that the white matter has many fibers, as it is the location through which numerous axons pass. In addition, there are nuclei ofglial cells.
The upper remainder of the larger figure is gray matter, highlighted in blue after clicking or hovering the cursor over it. Many neuronal and glial cell nuclei can be observed.
The gray matter is formed by three distinct regions in that are highlighted in different shades of blue hovering the mouse or clicking on the lower image.
The region closest to the white matter is the granular layer, formed by a large number of small neurons compactedly arranged. The next region is formed by neurons that have a very large cell body. They are called Purkinje cells.
The outermost layer of each fold is the molecular layer, which has relatively few neuronal cell bodies.
