part of cell differentiation in spinal cord ventral spinal cord development spinal cord motor neuron differentiation GO:0021522 The process in which neuroepithelial cells in the ventral neural tube acquire specialized structural and/or functional features of motor neurons. Motor neurons innervate an effector (muscle or glandular) tissue and are responsible for transmission of motor impulses from the brain to the periphery. Differentiation includes the processes involved in commitment of a cell to a specific fate. biological_process central nervous system neuron differentiation
