Motor Neurons (pMN)

All spinal cord motor neurons derive from a single ventral progenitor domain, located dorso-lateral to floor plate cells. Motor neurons acquire distinct subtype identities, which have been associated with the position of their cell bodies within the spinal cord, together with their axonal projection patterns in the periphery. Motor neuron generally project axons outside the spinal cord and primarily release the acetylcholine neurotransmitter.
