Abstract:
Heterotopic transplantations of fragments of neural tube have been performed in the chick embryo on stage 22 somites. Brachial motor centres were replaced by a posterior segment of spinal cord. As a result, synpatic patterns of Posterior Latissimus Dorsi (PLD) and Anterior Latissimus Dorsi (ALD) were modified : PLD exhibited numerous muscle fibers with a distributed innervation and ALD fibers had a large variability of intersynaptic lengths. Histochemical properties of myofibrillar ATPase activity in ALD and PLD muscles were close to those in controls, in spite of change in the innervation supply.
