| 1. | These axons also synapse with lower motor neurons in the ventral horns.
|
| 2. | Originates from ventral horn at lumbosacral spinal levels.
|
| 3. | Also, Onuf s nucleus is found almost symmetrically on both sides of the ventral horn.
|
| 4. | In essence the Renshaw cells regulate the firing of the alpha motor neuron leaving the ventral horn.
|
| 5. | These axons synapse with lower motor neurons in the ventral horns of all levels of the spinal cord.
|
| 6. | In the spinal cord, ?-MNs are located within the gray matter that forms the ventral horn.
|
| 7. | Motor pools that control flexor muscles are located dorsally to the ventral horn while those that control extensor muscles are located ventrally.
|
| 8. | For example, poliomyelitis is caused by a virus that specifically targets and kills motor neurons in the ventral horn of the spinal cord.
|
| 9. | In the developing spinal cord, Nkx-2.2 regulates IRX3 thereby contributing to the proper differentiation of the ventral horn neurons.
|
| 10. | These lower motor neurons, unlike those of the DL, are located in the ventral horn all the way throughout the spinal cord.
