Anatomical terminology

Thealar plate(oralar lamina) is aneural structurein theembryonic nervous system,part of thedorsalside of theneural tube,that involves the communication ofgeneral somaticandgeneral visceral sensory impulses.Thecaudalpart later becomes the sensory axon part of thespinal cord.

The alar plate specifically later on becomes thedorsal grayof thespinal cord,and also develops into the sensory nuclei ofcranial nervesV,VII,VIII,IX,andX.Theinferior olivary nucleus,mesencephalic nucleus of V,and main sensory nucleus of V are also developed from this plate. The cerebellum also develops from the alar plate, particularly from the rhombic lip. This is considered an exception to the general differentiation scheme from the alar plate, as the alar plate generally gives rise to sensory derivatives.
