| myogenic tonus | Contraction of a muscle caused by intrinsic properties of the muscle or by its intrinsic innervation. (05 Mar 2000) |
|---|---|
| myogenin | <molecular biology> Member of the MyoD family of muscle regulatory genes/proteins. Related to the myc proto-oncogene family. (18 Nov 1997) |
| myogenous | Myogenic 1. Originating in or starting from muscle. 2. Relating to the origin of muscle cells or fibres. Synonym: myogenous. (05 Mar 2000) |
| myoglobin | <physiology> Protein (17.5 kD) found in red skeletal muscle. It was the first protein for which the tertiary structure was determined by X-ray diffraction, by J.C.Kendrew's group working on sperm whale myoglobin. It is a single polypeptide chain of 153 amino acids, containing a haem group bonded via its ferric iron to two histidine residues. It binds oxygen noncooperatively and has a higher affinity for oxygen than haemoglobin at all partial pressures. In capillaries oxygen is effectively removed from haemoglobin and diffuses into muscle fibres where it binds to myoglobin which acts as an oxygen store. (18 Nov 1997) |
| myoglobinuria | Excretion of myoglobin in the urine; results from muscle degeneration, which releases myoglobin into the blood; occurs in certain types of trauma (crush syndrome), advanced or protracted ischemia of muscle, or as a paroxysmal process of unknown aetiology. Synonym: idiopathic paroxysmal rhabdomyolysis, Meyer-Betz disease, Meyer-Betz syndrome. (05 Mar 2000) |
| myoglobulin | Globulin present in muscle tissue. (05 Mar 2000) |
| myoglobulinuria | The excretion of myoglobulin in the urine. (05 Mar 2000) |
| myognathus | An unequal conjoined twin in which the rudimentary head of the parasite is attached to the lower jaw of the autosite by muscle and skin only. See: conjoined twins. Origin: myo-+ G. Gnathos, jaw (05 Mar 2000) |
| myogram | <investigation, physiology> A test which measures muscle response to nerve stimulation. Used to evaluate muscle weakness and to determine if the weakness is related to the muscles themselves or a problem with the nerves that supply the muscles. Abnormal results may be seen in myasthenia gravis, polymyositis, carpal tunnel syndrome, amyotrophic lateral sclerosis, alcoholic neuropathy, cervical spondylosis, dermatomyositis, familial periodic paralysis, Guillain-Barre syndrome, Lambert-Eaton syndrome, Friedreich's ataxia, mononeuritis multiplex, peripheral neuropathy, sciatic nerve disease and a variety of peripheral nerve disorders.

| myohaematin | <physiology> A red-coloured respiratory pigment found associated with hemoglobin in the muscle tissue of a large number of animals, both vertebrate and invertebrate. Origin: Myo- + haematin. Source: Websters Dictionary (01 Mar 1998) |
| myohemoglobin | <physiology> Protein (17.5 kD) found in red skeletal muscle. It was the first protein for which the tertiary structure was determined by X-ray diffraction, by J.C.Kendrew's group working on sperm whale myoglobin. It is a single polypeptide chain of 153 amino acids, containing a haem group bonded via its ferric iron to two histidine residues.

| myoclonus |
Myoclonus is brief, involuntary twitching of a muscle or a group of muscles. It describes a symptom and, generally, is not a diagnosis of a disease. The myoclonic twitches or jerks are usually caused by sudden muscle contractions; they also can result from brief lapses of contraction. Myoclonic jerks may occur alone or in sequence, in a pattern or without pattern. They may occur infrequently or many times each minute. ...
