1803 C. Bell Anat. Human Body III. ii. ii. 463 The duct of this gland [sc. the parotid] was discovered by Needham, and afterwards by Steno: it is very often called Steno's duct.]
1867 Quain's Elements Anat. (ed. 7) II. 816 The parotid duct, named also Stenson's duct (d. Stenonianus), appears at the anterior border of the gland.
1877 Encycl. Brit. VII. 222/2 The excretory duct of the gland, called Stenson's duct, passes forwards superficial to the masseter muscle.
1901 Proc. Zool. Soc. 1 i. 117 Hyrtl's figure of the relations between Stensen's duct and the buccal gland is misleading.
1977 G. D. Zuidema Johns Hopkins Atlas Human Functional Anat. xiii. 56/2 Surrounding the [oral] cavity and exiting into it are the major salivary glands: the parotid (Stensen's duct), the submaxillary (Wharton's duct), and the sublingual glands.
1901 W. A. N. Dorland Illustr. Med. Dict. s.v. Foramen Stenson's foramen, the two foramina behind the outer incisor teeth: each transmits an artery.
b. Each of two (sometimes four) canals through the bony palate, running from just behind the incisor teeth to each half of the nasal cavity; also the orifices of these canals in the bony palate.

1867 Quain's Elements Anat. (ed. 7) I. 45 This aperture may be seen to be divided into four smaller foramina, two of which placed laterally are the incisor foramina, called also foramina of Stenson.
1871 T. H. Huxley Man. Anat. Vertebrated Animals ii. 72 In the latter case they are the canals of Stenson... Glandular diverticula of the mucous membrane, supplied with nervous filaments from both the olfactory and the fifth pair, may open into these canals. They are called..the ‘organs of Jacobson’.
1893 Gunn & Hensman in H. Morris Treat. Human Anat. vii. 928 In the septal cartilage above the opening of Stenson's canal there is a small pouch which presents a minute opening below. This is the representative of the Jacobsonian organ. A strip of cartilage underneath this..is known as the Jacobsonian cartilage.
1936 L. B. Arey Developmental Anat. (ed. 3) vii. 182 Fusion between the median palatine processes and the palate is incomplete, so that in the midplane there is a gap, the incisive foramen, flanked by the incisive canals (of Stenson). These become covered with mucous membrane.
1969 tr. T. Donáth Anat. Dict. 480 Stenon's (Stensen's) foramen, foramen incisivum: one of the inferior openings of the incisive canals.
2. Stensen's experiment n. (see quot.).
