part of part of in taxon results in formation of anatomical entity cerebellar granular layer morphogenesis cerebellar granular layer formation GO:0021684 The process that gives rise to the cerebellar granule layer. This process pertains to the initial formation of a structure from unspecified parts. The granular layer is the innermost layer of the cerebellar cortex. This layer contains densely packed small neurons, mostly granule cells. Some Golgi cells are found at the outer border. Granule neurons send parallel fibers to the upper molecular layer, where they synapse with Purkinje cell dendrites. Mossy fibers from the pontine nuclei in the white matter synapse with granule cell axons, Golgi cell axons and unipolar brush interneuron axons at cerebellar glomeruli in the granule cell layer. cerebellar cortex formation anatomical structure formation involved in morphogenesis Vertebrata <vertebrates> granular layer of cerebellar cortex
