| axial muscle | <anatomy> One of the skeletal muscle's of the trunk or head. (05 Mar 2000) |
|---|---|
| axillary arch muscle | <anatomy> An anomalous muscle or tendinus slip that passes across the axilla from the pectoralis major to insert with the latissimus dorsi onto the humerus. Though to be a vestige of the panniculus carnosus muscle of lower mammals. Synonym: axillary arch muscle, axillary arch, pectorodorsal muscle. (05 Mar 2000) |
| bellies of digastric muscle | <anatomy> See: anterior belly of digastric muscle, posterior belly of digastric muscle. (05 Mar 2000) |
| bellies of omohyoid muscle | <anatomy> See: inferior belly of omohyoid muscle, superior belly of omohyoid muscle. (05 Mar 2000) |
| Bell's muscle | <anatomy> A band of muscular fibres, forming a slight fold in the wall of the bladder, running from the uvula to the opening of the ureter on either side, bounding the trigonum. (05 Mar 2000) |
| biopsy, muscle | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of muscle tissue for microscopic analysis. A muscle biopsy is used to distinguish between neurological and myopathic (muscle disease) disorders, identify muscular dystrophy, diagnose muscle infections and identify connective tissue disorders (necrotising vasculitis). (21 Mar 1998) |
| bipennate muscle | <anatomy> A muscle with a central tendon toward which the fibres converge on either side like the barbs of a feather. Synonym: musculus bipennatus. (05 Mar 2000) |
| Bochdalek's muscle | An occasional thin band of muscular fibres passing between the root of the tongue and the triticeal cartilage. Synonym: Bochdalek's muscle. (05 Mar 2000) |
| Bovero's muscle | <anatomy> The "sucking muscle," a labial muscle formed by sagittal fibres running from the skin to the mucous membrane. Synonym: Aeby's muscle, Bovero's muscle, compressor muscle of lips, Klein's muscle, Krause's muscle, mucocutaneous muscle, musculus cutaneomucosus. (05 Mar 2000) |
| Bowman's muscle | <anatomy> The smooth muscle of the ciliary body; it consists of circular fibres (Muller's muscle) and radiating fibres (meridional fibres, or Brucke's muscle); action, in contracting, its diameter is reduced (like a sphincter), reducing tensile (stretching) forces on lens, allowing it to thicken for near vision (accommodation). Synonym: musculus ciliaris, Bowman's muscle, ciliary ligament. (05 Mar 2000) |
| brachial muscle | <anatomy, muscle> Origin, lower two-thirds of anterior surface of humerus; insertion, coronoid process of ulna; action, flexes elbow; nerve supply, musculocutaneous, usually with a minor contribution from the radial. Synonym: musculus brachialis, brachial muscle. (05 Mar 2000) |
| brachiocephalic muscle | In animals, a compound muscle passing from the brachium or humerus to the head and the dorsal cervical raphe; the clavicular insertion or clavicle subdivides the muscle. Synonym: brachiocephalic muscle. (05 Mar 2000) |
| brachioradial muscle | <anatomy, muscle> Origin, lateral supracondylar ridge of humerus; insertion, front of base of styloid process of radius; action, flexes elbow and assists slightly in supination; nerve supply, (common) radial. Synonym: musculus brachioradialis, brachioradial muscle. (05 Mar 2000) |
| branch of glossopharyngeal nerve to stylopharyngeus muscle | <anatomy> Sole motor branch of the glossopharyngeal nerve to the stylopharyngeus muscle. Synonym: ramus musculi stylopharyngei nervi glossopharyngei. (05 Mar 2000) |
| Braune's muscle | <anatomy> The medial part of the musculus levator ani (pubococcygeus muscle) that passes from the body of the pubis around the anus to form a muscular sling at the level of the anorectal junction; it contracts to increase the perineal flexure during a peristalsis to maintain faecal continence and relaxes to allow defecation. Synonym: musculus puborectalis, Braune's muscle, puborectal muscle. (05 Mar 2000) |
