| muscular coat of oesophagus | Muscular layer of the oesophageal wall. Synonym: tunica muscularis oesophagi. (05 Mar 2000) |

| muscular coat of pharynx | 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) |
| muscular coat of rectum | Muscular layer of the wall of the rectum. Synonym: tunica muscularis recti. (05 Mar 2000) |
| muscular coat of small intestine | Muscular layer of the wall of the small intestine. Synonym: tunica muscularis intestini tenuis. (05 Mar 2000) |
| muscular coat of stomach | 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) |
| muscular coat of trachea | Muscular layer of the tracheal wall. Synonym: tunica muscularis tracheae. (05 Mar 2000) |
| muscular coat of ureter | Muscular layer of the ureteric wall. Synonym: tunica muscularis ureteris. (05 Mar 2000) |
| muscular coat of urinary bladder | Muscular layer of the wall of the urinary bladder. Synonym: tunica muscularis vesicae urinariae. (05 Mar 2000) |
| muscular coat of uterine tube | Muscular layer of the wall of the uterine tube. Synonym: tunica muscularis tubae uterinae. (05 Mar 2000) |
| muscular coat of uterus | <anatomy> Uterine smooth muscle. (18 Nov 1997) |
| muscular coat of vagina | Muscular layer of the vaginal wall. Synonym: tunica muscularis vaginae. (05 Mar 2000) |
| sclerotic coat | <anatomy> The tough white outer coat of the eyeball, covering approximately the posterior five sixths of its surface and continuous anteriorly with the cornea and posteriorly with the external sheath of the optic nerve. Origin: L., Gr. Skleros = hard (18 Nov 1997) |
| serous coat | serous membrane |
| egg coat | A layer of glycoproteins and other stuff which surrounds an egg (ovum), just outside of the egg's cell membrane. The coat protects the egg, and for organisms which practice external fertilization (fertilization outside of the parents' bodies) it can help prevent the sperm of other species from entering the egg. For the eggs of mammals, the egg coat is called the zona pellucida and for sea urchins (a popular study organism for developmental biologists) it is called the vitelline layer. (09 Oct 1997) |
| longitudinal layer of muscular coat | The outer, longitudinal layer of the smooth muscle of the muscular coat. Nomina Anatomica lists longitudinal layers of muscular coats (stratum longitudinale tunicae muscularis...) of the following: 1) colon (... Coli ); 2) rectum (... Recti ); 3) small intestine (... Intestini tenuis ); 4) stomach (... Gastrici ). Synonym: stratum longitudinale tunicae muscularis gastricae, stratum longitudinale tunicae muscularis. (05 Mar 2000) |
