The *spinal* somatic efferent neurons (GSE, 'somatomotor, or somatic motor fibers), arise from motor neuron cell bodies in the ventral horns of the gray matter within the spinal cord. They exit the spinal cord through the ventral roots, carrying motor impulses to skeletal muscle.

Of the somatic efferent neurons, there exist subtypes.

Cranial nerves also supply their own somatic efferent neurons to the extraocular muscles and some of the muscles of the tongue.
