| jugular gland | A firm supraclavicular lymph node, especially on the left side, sufficiently enlarged that it is palpable from the cutaneous surface; such a lymph node is so termed because it may be the first recognised presumptive evidence of a malignant neoplasm in one of the viscera. A signal node that is known to contain a metastasis from a malignant neoplasm is sometimes designated by an old eponym, Troisier's ganglion. Synonym: jugular gland, Virchow's node. (05 Mar 2000) |

| exocrine gland | <anatomy> A gland that secretes its products through ducts or canals, such as sweatglands or mammary glands. Compare: endocrine gland. (09 Oct 1997) |
| external salivary gland | <anatomy> A salivary gland situated in front of and below the ear. (27 Sep 1997) |
| unicellular gland | A single secretory cell such as a mucous goblet cell. (05 Mar 2000) |
| fibrous capsule of parotid gland | The part of the investing cervical fascia that ensheaths the parotid gland and is fixed above to the zygomatic arch. Synonym: fascia parotidea, fibrous capsule of parotid gland, parotid sheath. (05 Mar 2000) |
| fibrous capsule of thyroid gland | The fibrous sheath of the thyroid gland. Synonym: capsula fibrosa glandulae thyroideae. (05 Mar 2000) |
| uropygial gland | A compound alveolar gland of birds located on the dorsum of the tail or pygostyle; the secretion of this gland (fatty acids and wax) exits from a papilla on the dorsal surface at the base of the tail feathers; the bird applies the substance to its feathers by means of the bill when preening. The uropygial gland is lacking in some species but its waterproofing ability is essential to water birds. Synonym: glandula uropygius, oil glands, preen gland. (05 Mar 2000) |
| lacrimal gland | The gland that secretes tears; it consists of 6 to 12 separate compound tubuloalveolar serous glands, located in the upper lateral part of the orbit, and is partially divided into a smaller palpebral part and a larger orbital part by the aponeurosis of the levator palpebrae muscle. Synonym: glandula lacrimalis. (05 Mar 2000) |
| lacrimal gland enlargement | <radiology> Epithelial tumours (50%), benign adenoma (25%), carcinoma (25%); adenocystic carcinoma most common, lymphoid lesions (50%), lymphoma, benign lymphoid hyperplasia, pseudotumour, Sjogren syndrome, Mikulicz's, dermoid, metastasis (12 Dec 1998) |
| lactiferous gland | <anatomy> Milk producing gland of female mammals. An adapted sweat gland, it is made up of milk producing alveolar cells, surrounded by contractile myoepithelial cells, together with considerable numbers of fat cells. Milk production is hormonally controlled. (18 Nov 1997) |
| follicles of thyroid gland | <physiology> The small spherical vesicular components of the thyroid gland lined with epithelium and containing colloid in varying amounts. The colloid serves for storage of the thyroid hormone precursor, thyroglobulin. Synonym: follicles of thyroid gland. Origin: L. A small sac, dim. Of follis, bellows (05 Mar 2000) |
| follicular gland | <anatomy> A gland consisting of follicles. (05 Mar 2000) |
| levator muscle of thyroid gland | A fasciculus occasionally passing from the thyrohyoid muscle to the isthmus of the thyroid gland. Synonym: musculus levator glandulae thyroideae, elevator muscle of thyroid gland, Soemmerring's muscle. (05 Mar 2000) |
| lingual salivary gland depression | An indentation on the lingual surface of the mandible within which a portion of the submandibular gland lies; it appears radiographically as a sharply circumscribed ovoid radiolucency between the mandibular canal and the inferior border of the posterior mandible. Synonym: Stafne bone cyst, static bone cyst. (05 Mar 2000) |
| lobes of mammary gland | The 15 to 20 separate portions of the mammary gland that radiate from the central area deep to the nipple like wheel spokes and comprise the body of the mammary gland; each is drained by a single lactiferous duct. Synonym: lobi glandulae mammariae. (05 Mar 2000) |
