motor neuron development

Motor neuron development involves the process by which specialized nerve cells form in the spinal cord and brain, guiding muscle movement. It starts with stem cells that differentiate into motor neurons through genetic signals during embryonic growth. These neurons extend long projections called axons, which navigate through the body to reach muscle targets, forming connections called synapses. Proper development ensures coordinated movement, while errors can lead to movement disorders. This complex process is carefully regulated by many factors to establish functional motor pathways essential for voluntary and reflex actions.
