Primary Motoneurons Secondary Motoneurons Retrograde staining of motoneurons in the 9 th ventral root using horseradish peroxidase (HRP) reveals two populations of motoneurons. Primary motoneurons are born very early in embryonic development (during gastrulation) and innervate the swimming musculature of the tadpole. Secondary motoneurons are born later, beginning in larval stages and continuing through metamorphosis. Forehand, C.J. & Farel, P.B. (1982) Spinal cord development in anuran larvae: I. Primary and secondary motoneurons. J. Comp. Neurol., 209, 386-394.
