| clavicular part of pectoralis major muscle | pars clavicularis musculi pectoralis majoris, clavicular head of pectoralis major |
| mitochondria, muscle | Mitochondria of skeletal and smooth muscle. It does not include myocardial mitochondria for which mitochondria, heart is available. (12 Dec 1998) |
| physical elasticity of muscle | <anatomy> The quality of muscle that enables it to yield to passive physical stretch. (05 Mar 2000) |
| physiologic elasticity of muscle | The biologic quality, unique for muscle, of being able to change and resume size under neuromuscular control. (05 Mar 2000) |
| coccygeal muscle | <anatomy, muscle> Origin, spine of ischium and sacrospinous ligament; insertion, sides of lower part of sacrum and upper part of coccyx; action, assists in support of pelvic floor, especially when intra-abdominal pressures increase; nerve supply, third and fourth sacral. Synonym: musculus coccygeus, coccygeal muscle, musculus ischiococcygeus. (05 Mar 2000) |
| molluscan catch muscle | <biology> Muscle responsible for holding closed the two halves of the shell of bivalves. Specialise d to maintain tension with low expenditure of ATP. Rich in paramyosin. (18 Nov 1997) |
| Coiter's muscle | <anatomy, muscle> Origin, from orbital portion of musculus orbicularis oculi and nasal prominence; insertion, skin of eyebrow; action, draws medial end of eyebrow downward and wrinkles forehead vertically; nerve supply, facial. Synonym: musculus corrugator supercilii, Coiter's muscle, corrugator muscle, wrinkler muscle of eyebrow. (05 Mar 2000) |
| piriform muscle | <anatomy, muscle> Origin, margins of pelvic sacral foramina and greater sciatic notch of ilium; insertion, upper border of greater trochanter; action, rotates thigh laterally; nerve supply, nerve to piriformis (sciatic plexus).

| white muscle | <anatomy> A rapid or fast-twitch muscle in which pale large "white" fibres predominate; mitochondria and myoglobin are relatively sparse compared with red muscle; involved in phasic contraction. (05 Mar 2000) |
| white muscle disease | A myodegeneration most frequent in calves and lambs whose dams have been fed during gestation or longer on feeds, especially legumes, grown in certain areas where selenium is either deficient or unavailable in the soil. It has been recorded in many countries. It has been produced experimentally in several species of animals on low-selenium intake. A similar myopathy occurs naturally in goats, deer, foals, and dogs but proof of the aetiology is lacking. (merck veterinary manual, 5th ed) (12 Dec 1998) |
| plantar interosseous muscle | <anatomy> Three intrinsic muscles of foot; origin, the medial side of the third, fourth, and fifth metatarsal bones; insertion, corresponding side of proximal phalanx of the same toes; action, adducts three lateral toes; nerve supply, lateral plantar. Synonym: musculus interosseus plantaris. (05 Mar 2000) |
| plantar muscle | <anatomy, muscle> Origin, lateral supracondylar ridge; insertion, medial margin of tendo achillis and deep fascia of ankle; action, traditionally described as plantar flexion of foot; many investigators now believe the plantaris muscle to be primarily a proprioceptive organ; nerve supply, tibial nerve. Synonym: musculus plantaris, musculus tibialis gracilis, plantar muscle. (05 Mar 2000) |
