secretion into the cavity by a distinct tube or duct, which traverses 
the mucous membrane. To the latter alone the name of “salivary 
glands” is ordinarily appropriated, although the distinction 
between them and the smaller racemose glands is only one of 
convenience for descriptive purposes, their structure being more or 
less nearly identical ; and, since the fluids secreted by all become 
mixed in the mouth, their functions are, at all events in great part, 
common. Under the name of salivary glands are commonly

gland ; d, Steno’s duct; sm, submaxillary gland, traversed by the jugular veins (jv); 0, aperture 
of Steno’s duct. B, Part of the head with the lip drawn up to show (st.d) aperture of

included—(1) the “parotid” (p), situated very superficially on the 
side of the head, below or around the cartilaginous external 
auditory meatus, and the secretion of which enters the mouth by 
a duet (often called Steno’s or Stenson’s) which crosses the masseter 
muscle and opens into the upper and back part of the cheek 
(Fig. 19); and (2) the “submaxillary” (sm), situated in the neck 
near or below the angle of the mandible, and sending a long duet
