Abstract excerpt
The outgrowth of motor axons to the developing pectoral fin of the Japanese medaka fish (Oryzias latipes) was investigated both in wildtype embryos and in the pectoral finless (pl) mutants in which adults are missing pectoral fins. Late in embryogenesis the pectoral fin is a simple limb which contains two antagonist muscles which are innervated by presumptive motor neurons from the first four spinal segments...
