    • n gland In anatomy: A lymphatic ganglion; one of the numerous small, smooth, rounded organs which occur in the course of the lymphatics: formerly more fully called conglobate gland. See cut under lymphatic.
    • n gland Some secretory part or organ; a secreting crypt, follicle, or the like, generally of mucous or tegumentary surfaces, or a conglomeration of such parts composing some organ which secretes or excretes a substance peculiar to itself, as the liver, kidney, pancreas, parotid gland, testicle, etc., or the lacrymal, sebaceous, salivary, gastric, intestinal, and other glands. Glands, thus specifically defined, are either simple, consisting of a single secretory follicle or recess, or compound, consisting of an aggregate of such structures; the latter are also called tubular, saccular, racemose, etc., according to their intimate structure. The so-called ductless or vascular glands (see ) are not in this category, it being the essential character of a gland in this sense that it have an outlet for its special secretion. Glands of both these kinds were formerly classed as conglomerate glands, in distinction from conglobate or lymphatic glands.

    • n gland In human anatomy, a small conglomerate body about as large as a pea, lying near the tip of the coccyx, the exact structure and function of which is uncertain. It is intimately connected with the arteries and nerves, and is probably not of glandular character. It is also called Luschka's gland, after ita first describer, and by Arnold glomerulus arteriococcygeus.
