One of the prepared entrails of an animal, especially. Of a sheep, used for various purposes. See Catgut. 4. The sac of silk taken from a silkworm (when ready to spin its cocoon), for the purpose of drawing it out into a thread. This, when dry, is exceedingly strong, and is used as the snood of a fish line. Blind gut. See Caecum, . Origin: OE. Gut, got, AS. Gut, prob. Orig, a channel, and akin to geotan to pour. See FOUND to cast. Source: Websters Dictionary (01 Mar 1998) |
| gut-associated lymphoid tissue | <physiology> Peripheral lymphoid organ consisting of lymphoid tissue associated with the gut (Peyer's patches, tonsils, mesenteric lymph nodes and the appendix). It is especially rich in B-cells and is responsible for localised immunity to pathogens such as bacteria, viruses, and parasites. (20 Sep 2002) |
| postanal gut | An extension of the hindgut caudal to the point at which the anal opening is formed. Synonym: postcloacal gut, tailgut. (05 Mar 2000) |
| postcloacal gut | An extension of the hindgut caudal to the point at which the anal opening is formed. Synonym: postcloacal gut, tailgut. (05 Mar 2000) |
| preoral gut | The part of the embryonic foregut extending cephalad to the level of the oral plate and caudal to the pituitary diverticulum (Rathke's pouch). Synonym: preoral gut. (05 Mar 2000) |
| primitive gut | A flat sheet of intraembryonic endoderm that will change into a tubular gut due to the folding of embryonic body-head, tail and lateral body folds. Synonym: archenteron, celenteron, endodermal canal, subgerminal cavity. (05 Mar 2000) |
| endocrine cells of gut | Cells found throughout the lining of the gastrointestinal tract that contain regulatory peptide hormones and/or biogenic amines. The substances are located in secretory granules and act in an endocrine or paracrine manner. Some of these substances are also found in neurons in the gut. There are at least 15 different types of endocrine cells of the gut. Some take up amine precursors and have been called apud cells. However, most endocrine cells of the gut apparently have endodermal rather than neuroectodermal origin, so the relationship with apud cells is not clear. (12 Dec 1998) |
| artery of the pancreatic tail | Origin, splenic artery near the left gastroepiploic; distribution, the tail of the pancreas; anastomoses, with other pancreatic arteries. Synonym: arteria caudae pancreatis, caudal pancreatic artery. (05 Mar 2000) |

| rat-tail | 1. <veterinary> An excrescence growing from the pastern to the middle of the shank of a horse. 2. <zoology> The California chimaera. See Chimaera. Any fish of the genus Macrurus. See Grenadier. Source: Websters Dictionary (01 Mar 1998) |
| mare's-tail | 1. A long streaky cloud, spreading out like a horse's tail, and believed to indicate rain; a cirrus cloud. See Cloud. "Mackerel sky and mare's-tails Make tall ships carry low sails." (Old Rhyme) 2. <botany> An aquatic plant of the genus Hippuris (H.vulgaris), having narrow leaves in whorls. Source: Websters Dictionary (01 Mar 1998) |
| viral tail proteins | Proteins found in the tail sections of DNA and RNA viruses. It is believed that these proteins play a role in directing chain folding and assembly of polypeptide chains. (12 Dec 1998) |
| comet tail sign | In chest radiology, the curved appearance of pulmonary arteries and veins associated with round atelectasis, fibrosis associated with organizing pleurisy. Synonym: comet tail sign. (05 Mar 2000) |
| poly A tail | <molecular biology> A sequence of adenine nucleotides that get added to the 3' end of some primary transcript messenger RNA molecules in eukaryotes during post-transcriptional processing. The added tail is believed to confer stability to the molecule. Histone mRNA do not have poly A tail. The poly A tail is added post transcriptionally to the primary transcript as part of the nuclear processing of RNA yielding hnRNAs with 60-200 adenylate residues in the tail. In the cytoplasm the poly A tail on mRNAs is gradually reduced in length. The function of the poly A tail is not clear but it is the basis of a useful technique for the isolation of eukaryotic mRNAs. The technique uses an affinity column with oligo(u) or oligo(dT) immobilised on a solid support. If cytoplasmic RNA is applied to such a column, poly A rich RNA (mRNA) will be retained.
