GENERAL HISTOLOGY

Detailed explanation-1: -The cerebellar cortex has three distinct layers (Figure 1A). The most superficial layer contains inhibitory interneurons called basket cells and stellate cells, as well as excitatory climbing fibers and parallel fibers (the axons of granule cells).

Detailed explanation-2: -The top, outermost layer of the cerebellar cortex is the molecular layer. This layer contains the flattened dendritic trees of Purkinje cells, and the huge array of parallel fibers, from the granular layer, that penetrate the Purkinje cell dendritic trees at right angles.

Detailed explanation-3: -The cerebellar cortex is divided into three layers (Figure 5.6). The innermost layer, the granule cell layer, is made of 5 x 1010 small, tightly packed granule cells. The middle layer, the Purkinje cell layer, is only 1-cell thick.

Detailed explanation-4: -molecular layer-contains two main types of neurons: stellate cells and basket cells, which are scattered among dendritic ramifications and numerous thin axons that run parallel to the long axis of the folia.
