| myocomma | Origin: NL. See Myo-, and Comma. <anatomy> A myotome. (01 Mar 1998) |

| myocrismus | A creaking sound sometimes heard on auscultation of a contracting muscle. Origin: myo-+ G. Krizo, to squeak (05 Mar 2000) |
| myocutaneous | Synonym: musculocutaneous. Origin: myo-+ L. Cutis, skin (05 Mar 2000) |
| myocutaneous flap | A pedicle skin flap, often an island flap, with an attached subjacent muscle and its investments and blood supply. Synonym: musculocutaneous flap, myodermal flap. (05 Mar 2000) |
| myocyte | A muscle cell. Origin: myo-+ G. Kytos, cell (05 Mar 2000) |
| myocytolysis | Dissolution of muscle fibre. Origin: myo-+ G. Kytos, cell, + lysis, a loosening (05 Mar 2000) |
| myocytolysis of heart | Local loss of myocardial syncytium as a result of a metabolic imbalance, insufficient in intensity or duration (or both) to cause stromal injury or to elicit any reactive exudation. (05 Mar 2000) |
| myocytoma | <tumour> A benign neoplasm derived from muscle. (05 Mar 2000) |
| myoD | <molecular biology> Stands for myogenic determination. MyoD was described as a master regulatory gene for the determination of muscle cells, but muscle determination is now thought to involve a family of genes. It is normally only expressed in myoblasts and skeletal muscle cells, but if transfected into cells will convert many differentiated cells into muscle cells. The myoD gene codes for the myoD protein which then switches on the the transcription of many muscle specific genes. MyoD is a member of a family of genes that all code for nuclear proteins which have a basic DNA binding motif and a helix loop helix dimerisation domain (bHLH or mHLH proteins, b=basic, m=myogenic). They bind to a consensus sequence CANNTG and can form homodimers or heterodimers with other members of the bHLH superfamily. (18 Nov 1997) |
| MyoD heavy chain kinase | <enzyme> Required for actin activation of the magnesium atpase activity of dictyostelium myosin id (myod); specific for myod Registry number: EC 2.7.1.- Synonym: 110-kD protein kinase, dictyostelium, dictyostelium 110-kD protein (26 Jun 1999) |
| myod protein | A myogenic regulatory factor that controls myogenesis. Though it is not clear how its function differs from the other myogenic regulatory factors, myod appears to be related to fusion and terminal differentiation of the muscle cell. (12 Dec 1998) |
