The most interesting and peculiar portion of the nerve supply 
to the muscularis mucosae are the nerve terminations that apparently

correspond to motor plates in the striated muscles. These are 
moderately numerous in all well stained sections; where the nerve 
stems are not fully impregnated they do not appear; for they are 
much more difficult to tinge than the nerves themselves. . 
Apparently there are two varieties of these end-terminations 
present in almost equal proportion. Usually both are derived from 
bundles of four or more fibres which send off at right angles to the
