| myotonus | A tonic spasm or temporary rigidity of a muscle or group of muscles. Origin: myo-+ G. Tonos, tension, stretching (05 Mar 2000) |

| myotony | Muscular tonus or tension. Synonym: myotone. Origin: myo-+ G. Tonos, tension (05 Mar 2000) |
| myotoxin | <protein> From a family of small basic proteins (42-45 amino acids) in rattlesnake venom. Induce rapid necrosis of muscle. (18 Nov 1997) |
| myotrophy | Nutrition of muscular tissue. Origin: myo-+ G. Trophe, nourishment (05 Mar 2000) |
| myotube | <biology> Elongated multinucleate cells (three or more nuclei) that contain some peripherally located myofibrils. They are formed in vivo or in vitro by the fusion of myoblasts and eventually develop into mature muscle fibres that have peripherally located nuclei and most of their cytoplasm filled with myofibrils. In fact, there is no very clear distinction between myotubes and muscle fibres proper. (18 Nov 1997) |
| myotubular myopathy | Slowly progressive generalised muscle weakness and atrophy beginning in childhood; on biopsy of skeletal muscle, the nuclei of most muscle fibres are seen to be located near the centre of a small fibre (the normal position for a 10-week embryo) rather than at the periphery of the fibre; familial incidence. Autosomal dominant recessive and X-linked [310400] forms occur. Synonym: myotubular myopathy. Distal myopathy, myopathy affecting predominantly the distal portions of the limbs; onset is usually after age 40, with weakness and wasting of small muscles of the hands; The infantile form and the Swedish later-onset are autosomal dominant and there is a Japanese late-onset type that is recessive. Minicore-multicore myopathy, an uncommon nonprogressive myopathy with early onset, proximal weakness, and hypotonia. Muscle fibres show focal defects of oxidative and myofibrillar adenosine triphosphatase enzymes with disorganization of myofibril ultrastructure. Mitochondrial myopathy, weakness and hypotonia of muscles, primarily those of the neck, shoulder, and pelvic girdles, with onset in infancy or childhood; on biopsy, giant, bizarre mitochondria are seen located between muscle fibrils just beneath the sarcolemma. The dominant form is due to deletion of mitochondrial DNA and the recessive form is due to a complex deficiency. (05 Mar 2000) |
| myotubule | Former term for myotube. (05 Mar 2000) |
| myovascular sphincter | A sphincter having a muscular and a vascular (usually venous) component. See: myovenous sphincter. (05 Mar 2000) |
| myovenous sphincter | A sphincter having a muscular and a venous component, e.g., at the pharyngoesophageal junction and anal canal. (05 Mar 2000) |
| myoviridae | A family of bacteriophages which are characterised by complex contractile tails. (12 Dec 1998) |
