Axon growth in tendon organs of botulinum-paralyzed neonatal mouse muscles.
Paralysis of neonatal mouse gluteus muscles with botulinum toxin stimulated the growth not only of motor nerve terminals but also of the terminals of the sensory axons innervating the tendon organs. However, the adult mouse tendon organ axons, unlike motor nerve terminals, did not sprout in response to paralysis.
