| myofibroma | <oncology, tumour> A tumour containing muscle and connective tissue cells. (09 Oct 1997) |
|---|---|
| myofibromatosis | A condition characterised by multiple formations of myofibromas (leiomyoma). (12 Dec 1998) |
| myofibrosis | Chronic myositis with diffuse hyperplasia of the interstitial connective tissue pressing upon and causing atrophy of the muscular tissue. Myofibrosis cordis, myofibrosis of the heart walls. (05 Mar 2000) |
| myofibrositis | Inflammation of the perimysium. (05 Mar 2000) |
| myofilaments | The ultramicroscopic threads of filamentous proteins making up myofibrils in striated muscle. Thick ones contain myosin and thin ones actin; thick and thin myofilaments's also occur in smooth muscle fibres but are not regularly arranged in discrete myofibrils and thus do not impart a striated appearance to these cells. (05 Mar 2000) |
| myofunctional | 1. Relating to function of muscles. 2. In dentistry, relating to the role of muscle function in the aetiology or correction of orthodontic problems. (05 Mar 2000) |
| myofunctional therapy | Therapy of malocclusion and other dental and speech disorders utilizing muscular exercises of the tongue and lips; most often intended to alter a tongue thrust swallowing pattern. (05 Mar 2000) |
| myogalid | <zoology> One of the Myogalodae, a family of Insectivora, including the desman, and allied species. Origin: Myo- + Gr. A weasel. Source: Websters Dictionary (01 Mar 1998) |
| myogen | Proteins extracted from muscle with cold water, largely the enzymes promoting glycolysis; from the residue, alkaline 0.6 m KCl extracts actin and myosin as actomyosin, with myosin further separable into two meromyosins by proteinase treatment. Synonym: myosinogen. Origin: myo-+ G. -gen, producing (05 Mar 2000) |
| myogenesis | <physiology> The developmental sequence of events leading to the formation of adult muscle that occurs in the animal and in cultured cells. In vertebrate skeletal muscle the main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motoneurons. at this stage they can be regarded as mature muscle fibres. (18 Nov 1997) |
| myogenetic | Myogenic 1. Originating in or starting from muscle. 2. Relating to the origin of muscle cells or fibres. Synonym: myogenous. (05 Mar 2000) |
| myogenic paralysis | Inflammation of the anterior cornua of the spinal cord; an acute infectious disease caused by the poliomyelitis virus and marked by fever, pains, and gastroenteric disturbances, followed by a flaccid paralysis of one or more muscular groups, and later by atrophy. Synonym: acute atrophic paralysis, myogenic paralysis. (05 Mar 2000) |
| myogenic potential | Action potential of muscle. (05 Mar 2000) |
| myogenic regulatory factors | A family of muscle-specific transcription factors which bind to DNA in control regions and thus regulate myogenesis. All members of this family contain a conserved helix-loop-helix motif which is homologous to the myc family proteins. These factors are only found in skeletal muscle. Members include the myod protein (myod protein), myogenin, myf-5, and myf-6 (also called mrf4 or herculin). (12 Dec 1998) |
| myogenic theory | That cardiac movements are due mainly to stimuli originating in the heart muscle itself and that the heart does not act solely in response to nerve stimulation. (05 Mar 2000) |
