| muscular coat of gallbladder | Muscular layer of the wall of the gallbladder. Synonym: tunica muscularis vesicae biliaris, tunica muscularis vesicae felleae. (05 Mar 2000) |

| 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) |
| muscular dystrophy | A group of diseases characterised by progressive degeneration and/or loss of muscle fibres without nervous system involvement. All or nearly all of them have a hereditary origin but details of the type of genetic defect and of the prognosis for the disease vary from type to type. Duchenne muscular dystrophy (pseudohypertrophic muscular dystrophy) is the most common form. It is due to a sex-linked recessive allele and this is expressed as an absence of the protein dystrophin, the disease in boys shows extensive but insufficient muscle fibre reformation from satellite cells.

| muscular fascia of extraocular muscle | Muscular fascia; the part of the orbital fascia that envelops the extraocular muscles; it is thin posteriorly but becomes thicker where it is continuous with the bulbar sheath; the fascial sheaths of the four rectus muscles are connected by an intermuscular membrane. Synonym: fascia muscularis musculorum bulbi, fascia of extraocular muscles, muscular fascia of extraocular muscle. (05 Mar 2000) |
| muscular fibril | <cell biology> Long cylindrical organelle of striated muscle, composed of regular arrays of thick and thin filaments and constituting the contractile apparatus. (18 Nov 1997) |
