| salt gland | A compound tubular gland, located around the eyes and nasal passages in marine animals and birds, the physiology of which figures in water-electrolyte balance. The pekin duck serves as a common research animal in salt gland studies. A rectal gland or rectal salt gland in the dogfish shark is attached at the junction of the intestine and cloaca and aids the kidneys in removing excess salts from the blood. (storer, usinger, stebbins & nybakken: general zoology, 6th ed, p658) (12 Dec 1998) |
| prostate gland | A gland in the male that surrounds the neck of the bladder and urethra. The prostate contributes to the seminal fluid. (16 Dec 1997) |
| hibernating gland | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| sebaceous gland | A normal gland of the skin which empties an oily secretion into the hair follicle near the surface of the skin. (12 Dec 1998) |
| holocrine gland | A gland whose secretion consists of disintegrated cells of the gland itself, e.g., a sebaceous gland, in contrast to a merocrine gland. (05 Mar 2000) |
| seminal gland | <anatomy> The paired glands at the base of the bladder that produce seminal fluid and fructose. (09 Oct 1997) |
| sentinel gland | A single enlarged lymph node in the omentum that may be an indication of an ulcer opposite to it in the greater or lesser curvature of the stomach. (05 Mar 2000) |
| pyramidal lobe of thyroid gland | <anatomy> An inconstant narrow lobe of the thyroid gland that arises from the upper border of the isthmus and extends upward, sometimes as far as the hyoid bone; it marks the point of continuity with the thyroglossal duct. Synonym: lobus pyramidalis glandulae thyroideae, Lallouette's pyramid, Morgagni's appendix, pyramid of thyroid. (05 Mar 2000) |
| seromucous gland | A gland in which some of the secretory cells are serous and some mucous, a gland whose cells secrete a fluid intermediate between a watery and a viscous mucoid substance. Synonym: glandula seromucosa. (05 Mar 2000) |
| serous gland | An exocrine gland that produces a watery, protein rich secretion, as opposed to a carbohydrate rich mucous secretion. (18 Nov 1997) |
| sexual gland | See: testis, ovary. (05 Mar 2000) |
| sheath of thyroid gland | Covering of the thyroid gland external to its capsule formed by a splitting of the pretracheal layer of deep cervical fascia at the gland's posterior border; the anterior lamina covers the gland anterolaterally, attaching to the arch of the cricoid cartilage superior to the isthmus of the gland (causing it to move with the trachea during elevation/depression of the larynx); the posterior lamina passes posterior to the oesophagus to blend with the buccopharyngeal fascia; inferiorly, the sheath extends along the inferior thyroid veins to open into the superior mediastinum (hence, expansion of the thyroid, as by goiter, can take this direction). (05 Mar 2000) |
| stroma of thyroid gland | The connective tissue that supports the lobules and follicles of the thyroid gland. Synonym: stroma glandulae thyroideae. (05 Mar 2000) |
| sublingual gland | The smallest of the three major salivary glands. It is located. It lies under the floor of the mouth close to the midline. (12 Dec 1998) |
