(cell body) and an axon.

Dendrites: Each granule cell has 3 - 4 stubby dendrites which end in a claw. Each of the dendrites are only about 15 um in length.

Soma: Granule cells all have a small soma diameter of approximately 10 um.

Axon: Each granule cell sends a single axon onto the Purkinje cell dendritic tree. The axon has an extremely narrow diameter: ½ micrometre.

Synapse: 100-300,000 granule cell axons synapse onto
