1. Gamma motor neurons , like all cells, express specific genetic markers at birth. 2. The patient s histological examination showed severe reduction in lower motor neurons . 3. This connection between motor neurons and muscles is called the neuromuscular junction. 4. It is the neurotoxin responsible for the motor neuron degeneration syndrome lathyrism. 5. These axons also synapse with lower motor neurons in the ventral horns. 6. In a third experiment, the motor neurons of newborn rats were severed. 7. The lower motor neuron ( LMN ) of these muscles is damaged. 8. Another distinguishing molecular marker of gamma motor neurons is transcription factor Err3. 9. A single motor neuron may innervate many summation or a tetanic contraction. 10. As a result, alpha motor neurons become hyperactive, and muscles constantly contract.
