| circular layers of muscular tunics | The inner, circular layer of the smooth muscle of the muscular coat. Nomina Anatomica lists circular layers of muscular coats (stratum circulare tunicae muscularis...) of the following: 1) colon (... Coli ); 2) rectum (... Recti ); 3) small intestine (... Intestini tenuis ); 4) stomach (... Gastrici ). Synonym: stratum circulare tunicae muscularis gastricae, stratum circulare tunicae. (05 Mar 2000) |

| Werdnig-Hoffmann muscular atrophy | Transmitted as autosomal recessive on chromosome 5q. Progressive dysfunction of the anterior horn cells in the spinal cord and brainstem cranial nerves with profound weakness and bulbar dysfunction occurring in the first two years of life. Three groups, based on age of clinical onset, are recognised. Synonym: familial spinal muscular atrophy, Hoffmann's muscular atrophy, infantile muscular atrophy, infantile progressive spinal muscular atrophy, progressive infantile spinal muscular atrophy, Werdnig-Hoffmann disease, Werdnig-Hoffmann muscular atrophy.

| muscular | <anatomy> Pertaining to or composing muscle. Origin: L. Muscularis (18 Nov 1997) |
| muscular artery | <anatomy, artery> An artery with a tunica media composed principally of circularly arranged smooth muscle. Synonym: distributing artery, medium artery. (05 Mar 2000) |
| muscular asthenopia | Asthenopia due to imbalance of the extrinsic ocular muscles. (05 Mar 2000) |
| muscular atrophy | Derangement in size and number of muscle fibres occurring with aging, reduction in blood supply, or following immobilization, prolonged weightlessness, malnutrition, and particularly in denervation. (12 Dec 1998) |
| muscular atrophy, spinal | Progressive degenerative disorder of motor neurons in the spinal cord, brainstem, and motor cortex, manifested clinically by muscular weakness, atrophy, and corticospinal tract signs in varying combinations. (12 Dec 1998) |
| muscular coat | 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) |
| muscular coat of bronchi | Muscular layer of the bronchial wall. Synonym: tunica muscularis bronchiorum. (05 Mar 2000) |
| muscular coat of colon | Muscular layer of the wall of the colon. Synonym: tunica muscularis coli. (05 Mar 2000) |

| muscular coat of female urethra | Muscular layer of the wall of the female urethra. Synonym: tunica muscularis urethrae femininae. (05 Mar 2000) |
| 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) |
