| tunica muscularis | The muscular, usually middle, layer of a tubular structure; for most of the gastrointestinal tract, it consists of an outer longitudinal layer of muscle and an inner circular layer. Synonym: tunica muscularis. (05 Mar 2000) |

| tunica muscularis bronchiorum | Muscular layer of the bronchial wall. Synonym: tunica muscularis bronchiorum. (05 Mar 2000) |
| tunica muscularis coli | Muscular layer of the wall of the colon. Synonym: tunica muscularis coli. (05 Mar 2000) |
| tunica muscularis ductus deferentis | Muscular layer of the wall of the ductus deferens. Synonym: tunica muscularis ductus deferentis. (05 Mar 2000) |
| tunica muscularis gastrica | Muscular tunic of the stomach, consisting of smooth muscles arranged in three fairly well defined layers: an outer longitudinal layer, continuous with that of the oesophagus but dividing at the cardia into two bands which run along the greater and lesser curvatures, leaving the middle areas of the anterior and posterior walls devoid of longitudinal fibres, and then coalescing in the pyloric region into a complete layer which is continuous with the longitudinal coat of the duodenum. The middle circular layer is most complete and strongest, continuous with the circular layer of the oesophagus at the cardia; it thickens progressively toward the pylorus, ultimately forming the muscular ring of the pyloric sphincter. The inner, oblique layer is unique to the stomach and is most strongly developed in the fundic region and absent along the lesser curvature. This absence contributes to the formation of the "gastric canal." See: oblique fibres of stomach. Synonym: tunica muscularis gastrica, tunica muscularis ventriculi. (05 Mar 2000) |
| tunica muscularis intestini tenuis | Muscular layer of the wall of the small intestine. Synonym: tunica muscularis intestini tenuis. (05 Mar 2000) |
| tunica muscularis oesophagi | Muscular layer of the oesophageal wall. Synonym: tunica muscularis oesophagi. (05 Mar 2000) |
| tunica muscularis pharyngis | Muscular layer of the pharyngeal wall. In contrast with the muscular coats of the rest of the gastrointestinal tract (except anal canal), that of the pharynx has an outer circular layer and an inner longitudinal layer. Synonym: tunica muscularis pharyngis. (05 Mar 2000) |
| tunica muscularis recti | Muscular layer of the wall of the rectum. Synonym: tunica muscularis recti. (05 Mar 2000) |
| tunica muscularis tracheae | Muscular layer of the tracheal wall. Synonym: tunica muscularis tracheae. (05 Mar 2000) |
| tunica muscularis tubae uterinae | Muscular layer of the wall of the uterine tube. Synonym: tunica muscularis tubae uterinae. (05 Mar 2000) |

| tunica muscularis uteri | <anatomy> Uterine smooth muscle. (18 Nov 1997) |
| tunica muscularis vaginae | Muscular layer of the vaginal wall. Synonym: tunica muscularis vaginae. (05 Mar 2000) |
