Question

Quizplus · Accepted Answer

Motor neurons arise primarily from the basal plate, which is one of the two main subdivisions of the neural tube. The basal plate gives rise to ventral motor neurons that control muscle movement. The alar plate, on the other hand, gives rise to dorsal sensory neurons that receive and transmit sensory information. The ependyma is a layer of cells lining the ventricles of the brain and central canal of the spinal cord, and the neural crest gives rise to various types of neural and non-neural cells, including some sensory neurons and glial cells.
