Abstract:
Wistar strain male albino rats were sacrificed at 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 and 21 days of age, and the histochemical properties of nerve cell and muscle fibre were examined.
We obtained the following differentiation process in the muscle with postnatal growth;
phase I (newborn-7 days) undifferentiated fibre
phase II (7-15 days) FT fibre ST fibre
phase III (after 15 days) FG fibre FOG fibre SO fibre
On the other hand, histochemical differentiation of nerve cell was recognized earlier than that of muscle fibre, and there was no redistribution of soma type with growth.
Therefore, it may be said bhat histochemical differentiation process in the muscle is largely effected by the neuronal influences exerted from the lower motoneurons.
