"Physiologists divide nerve-fibers, which sort the nerves, into two classes, afferent and efferent. Impressions are made around the peripheral afferent fiber-endings; these make sensations which have been transmitted to the middle on the nervous program. Efferent nerve-fibers have impulses out from the center for their endings. Many of these visit muscles and are therefore termed motor impulses; some are secretory and enter glands; a portion are inhibitory, their perform staying to restrain secretion.
