Some effects of de-afferentation on the developing amphibian nervous system.
A N adult anuran can still walk or swim if the nerves supplying one or even two limbs are de-afferentated (Gray, 1950). However, in a developing amphibian, a limb at motile stages becomes paralysed when deprived of its sensory input. A sequence of degenerative changes then follow in the cord and in peripheral nerves. Tadpoles of Bufo marinus and late embryos of Eleutherodactylus martinicensis h...
متن کاملThe innervation of the hind limb of Eleutherodactylus martinicensis: further comparison of cell and fiber numbers during development.
In montages of electron micrographs of the sciatic nerve of Eleutherodactylus martinicensis, the numbers of fibers of all classes have been counted, from the 8-5 day embryo, through the early juvenile to the adult. These counts have been compared with the total numbers of cells in the lumbar ventral horn plus those in the lumbar spinal ganglia 8, 9 and 10. In the embryo, both sets of counts ris...

متن کاملFurther experiments on the innervation and function of grafted supernumerary limbs in the embryo of Eleutherodactylus martinicensis by ARTHUR HUGHES
PREVIOUS studies on the transplantation of limbs in the embryo of Eleutherodactylus martinicensis have shown that supernumerary limbs tend to be less well innervated than are corresponding replacing grafts, and that the innervation of the former, either autografts or homografts, is progressively less extensive with increase in time after operation. The degree to which grafted supernumerary fore...
