The morphology of the normal end-plate in lambs as revealed by silver impregnation and light microscopy

A technique employing silver impregnation can be used on frozen formalin-fixed material for demonstrating ovine motor end-plates. The morphology of ovine motor end-plates is variable but broadly similar to that described in other species. The end-plates are oval with approximate dimensions of 33 X 17 micrometer. The distal ramifications of the nerve fibre show terminal and sub-terminal vesicles. The endings are flimsy or robust and the latter have single, dual or multiple terminations.
