Abstract
THE distribution of acetylcholine receptors and the onset of functional innervation at the neuromuscular junction during development have been much investigated1–3, as have the events during regeneration and reinnervation of muscle4. Although the first appearance of acetylcholine (ACh) sensitivity of the membrane has been charted in chick and mouse myoblasts differentiating in tissue culture5, previous studies in vivo have either not tested for the initial appearance of ACh sensitivity2, or found the muscle membrane to be already sensitive to externally applied ACh1. In the present study on Xenopus embryos we have followed the initial appearance of membrane depolarisation in response to applied ACh and the onset of functional innervation in differentiating myotome muscle in vivo.
