The =sublingual gland= has an arrangement similar to that of the ox. The
posterior part (Glandula sublingualis grandicanalaris) is reddish-yellow
in color, and is about two inches (ca. 5 cm.) long, and half an inch
wide; its posterior end is in relation to the submaxillary gland and its
duct. The anterior part is much larger, being two or three inches (ca. 5
to 7 cm.) long and about twice the width and thickness of the posterior
part. All or most of the ducts from the posterior part unite to form the
=ductus sublingualis major=, which opens near the ductus submaxillaris.
Eight or ten =ductus sublinguales minores= convey the secretion from the
anterior part through the floor of the mouth.
