| solitary nodules of intestine | Minute collections of lymphoid tissue in the mucosa of the small and large intestines, being especially numerous in the caecum and appendix. Synonym: folliculi lymphatici solitarii, solitary follicles, solitary glands, solitary nodules of intestine. (05 Mar 2000) |

| solitary nucleus | Gray matter located in the dorsomedial part of the medulla oblongata associated with the solitary tract. The solitary nucleus receives inputs from most organ systems including the terminations of the facial, glossopharyngeal, and vagus nerves. It is a major coordinator of autonomic nervous system regulation of cardiovascular, respiratory, gustatory, gastrointestinal, and chemoreceptive aspects of homeostasis. The solitary nucleus is also notable for the large number of neurotransmitters which are found therein. (12 Dec 1998) |
| solitary osteocartilaginous exostosis | <oncology, tumour> A benign cartilaginous neoplasm that consists of a pedicle of normal bone with a rim of proliferative cartilage cells, often occurs near the ends of long bones, multiple osteochondromas are inherited and referred to as hereditary multiple exostoses. (27 Sep 1997) |
| solitary tract | A slender, compact fibre bundle extending longitudinally through the dorsolateral region of the medullary tegmentum, surrounded by the nucleus of the solitary tract, below the obex decussating over the central canal, and descending over some distance into the upper cervical segments of the spinal cord. It is composed of primary sensory fibres that enter with the vagus, glossopharyngeal, and facial nerves, and in part convey information from stretch receptors and chemoreceptors in the walls of the cardiovascular, respiratory, and intestinal tracts; in rostral parts of the tract impulses are generated by the receptor cells of the taste buds in the mucosa of the tongue. Its fibres are distributed to the nucleus of the solitary tract. Synonym: tractus solitarius, fasciculus rotundus, fasciculus solitarius, funiculus solitarius, Gierke's respiratory bundle, Krause's respiratory bundle, round fasciculus, solitary bundle, solitary fasciculus. (05 Mar 2000) |
| nucleus of solitary tract | A slender cell column extending sagittally through the dorsal part of the medulla oblongata, beneath the floor of the rhomboid fossa, immediately lateral to the limiting sulcus. It is the visceral sensory (visceral afferent) nucleus of the brainstem, receiving the afferent fibres of the vagus, glossopharyngeal, and facial nerves by way of the solitary tract. The caudal two-thirds of the nucleus processes impulses originating in the pharynx, larynx, intestinal and respiratory tracts, and heart and large blood vessels; its rostral one-third receives impulses from the taste buds and is known as the rhombencephalic gustatory nucleus. Synonym: nucleus tractus solitarii. (05 Mar 2000) |
| gastric follicles | Branched tubular glands lying in the mucosa of the fundus and body of the stomach; such glands contain parietal cells that secrete hydrochloric acid, zymogen cells that produce pepsin, and mucous cells. Synonym: glandulae gastricae, glandulae propriae, fundus glands, gastric follicles, Wasmann's glands. (05 Mar 2000) |
| Montgomery's follicles | A number of small mammary glands forming small rounded projections from the surface of the areola of the breast; they enlarge with pregnancy and during lactation secrete a substance presumed to resist chapping. Synonym: glandulae areolares, Montgomery's follicles, Montgomery's glands. (05 Mar 2000) |
| sebaceous follicles | Numerous holocrine glands in the dermis that usually open into the hair follicles and secrete an oily semifluid sebum. Synonym: glandulae sebaceae, oil glands, sebaceous follicles. (05 Mar 2000) |
| splenic lymph follicles | Small nodular masses of lymphoid tissue attached to the sides of the smaller arterial branches. Synonym: folliculi lymphatici lienales, malpighian bodies, malpighian corpuscles, malpighian glands, malpighian nodules, splenic corpuscles, splenic lymph nodules. (05 Mar 2000) |
| intestinal follicles | The tubular glands in the mucous membrane of the small and large intestines. Synonym: glandulae intestinales, Galeati's glands, intestinal follicles, Lieberkuhn's crypts, Lieberkuhn's follicles, Lieberkuhn's glands. (05 Mar 2000) |
| 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) |
| Lieberkuhn's follicles | The tubular glands in the mucous membrane of the small and large intestines. Synonym: glandulae intestinales, Galeati's glands, intestinal follicles, Lieberkuhn's crypts, Lieberkuhn's follicles, Lieberkuhn's glands. (05 Mar 2000) |
| lingual follicles | Collections of lymphoid tissue in the mucosa of the pharyngeal part of the tongue posterior to the terminal sulcus collectively forming the lingual tonsil. Synonym: lenticular papillae, lingual follicles. (05 Mar 2000) |
| afferent lymphatic | A lymphatic vessel entering, or bringing lymph to, a node. Synonym: vas lymphaticum afferens, afferent vessel. (05 Mar 2000) |
| aggregated lymphatic nodules | Lymphoid organs located in the sub mucosal tissue of the mammalian gut containing very high proportions of IgA secreting precursor cells. The patches have B and T dependent regions and germinal centres. A specialised epithelium lies between the patch and the intestine. Involved in gut associated immunity. (18 Nov 1997) |
