Spinal cord ventral horn motor neuron alpha
| Name: | Spinal cord ventral horn motor neuron alpha |
| Description: | Large lower motor neuron of the brainstem and spinal cord. They innervate extrafusal muscle fibers of skeletal muscle and are directly responsible for initiating their contraction. Alpha motor neurons are distinct from gamma motor neurons, which innervate intrafusal muscle fibers of muscle spindles. |
| Synonym(s): | alpha motoneuron, lower motor neuron, alpha motor neuron |
| Has role: | Principal neuron role |
