The relationship of nerve to myoblasts and newly-formed secondary myotubes in the fourth lumbrical muscle of the rat foetus.


The formation of normal numbers of skeletal muscle fibres depends on functional innervation of the muscle before and during the period of secondary myotube formation, but little has been known about the physical relationship between nerve terminals and the myoblasts and secondary myotubes over the critical period.
