Gland Cells of a Dog

A section of the submaxillary gland of a dog. Showing gland cells, b, and a duct, a, in section.

Diagrammatic representation of the submaxillary gland of the dog with its nerves and blood vessels. Labels: sm. gld., the submaxillary gland into the duct (sm. d.) of which a cannula has been tied. The sublingual gland and duct are not proceeding from the facial nerve, becoming conjoined with the lingual at n.l'., and afterwards diverging and passing to the gland along the duct; sm. gl., submaxillary ganglion with its roots; n. l., the lingual nerve proceeding to the tongue; a. car., the carotid artery. two branches of which, a. sm. a. and r. sm. p. pass to the anterior and posterior parts of the gland; v. sym., the conjoined vagus and sympathetic trunks; gl. cer. s., the superior cervical ganglion, two branches of which forming a plexus, a.f., over the facial artery are distributed (n.sym.sm.) along the two glandular arteries to the anterior and posterior portion of the gland. The arrows indicate the direction taken by the nervous impulses; during reflex stimulations of the gland they ascend to the brain by the lingual and descend by the chorda tympani.
