Schematic of motoric and sensory nuclei in spinal cord and brain stem

Schematic of motoric and sensory nuclei in spinal cord and brain stemSchematic of the distribution principles of the motoric and sensory areas (formed from alar and basal plates) in spinal cord and brain stem.Upper schematic: Spinal cordLower schematic: Brain stemThe further cranial and continuing upwards into the mesencephalon (midbrain) the more the distribution changes.

Generally this distribution continues up to the diencephalon.Embryologically the distribution existed along the entire neural tube, but in the development of di- and telencephalon it is modified so much as to be no longer recognizable. Especially the motoric parts are missing.
