The Salival Glandules of the Lower Jaw, together with those under the Tongue, Dissected.
A A, The Two Inferior Maxillary Glands, which are Repre∣sented in Situ, Tab. 15. Fig. 1. M M, Compos'd of divers Lobuli, Inclos'd in One Membrane.
B B, The Glandulae Sublinguales Cover'd with their Common Membrane; One of which Glandules is Represented in Situ, in the last mention'd Table, Fig. 2. W.
C C, The Trunks of the Two Arteries which Spring from the Carotides, and Convey Blood into the above mention'd Salival Glands.
D D, Two Branches of Arteries, Arising from the last mention'd Trunks, which pass to the Tongue. Besides the Branches now men∣tion'd, each of these Large Trunks sends out another considerable Branch Exprest Tab. 12. Fig. 4. F. which is Employ'd on the Muscles of the Face.
E, The Trunk of the Vein Arising from the Extremitties of the Arteries of those Glands, and those of the Neighbouring Parts.
F, A Branch of the Fifth Pair of Nerves.
G G, The Salival Ducts of the Inferior Maxillary Glands, as they pass to their Excretory Pores at the Extremity of each Papilla plac'd under the Tongue.
H H, The Two Papillae last mention'd, where the Excretory Ducts of the Sublingual Glands also empty themselves at the same Pores with the Two Salival Ducts. This Protrusion of the Sali∣val Ducts which Frame the Papillae, is a necessary Contrivance to Hinder any Particle of the Masticated Aliment from Entring those Ducts, or the Exceted Saliva from Repassing them.
I, The Salival Duct of the Right Side Open'd according to its Length, and Expanded.
K, A Small Stone as it Appear'd lying in the above mention'd Duct: It was of a bright Yellow Colour, not unlike that of Arumpigmentum. In Dissecting these Parts the Lesser End of it happen'd to Break off, as it is here Exprest.
