| musculi intertransversarii posteriores cervicis | Origin, lateral part: posterior tubercle of cervical transverse process; medial part: transverse process; insertion, corresponding parts of next superior transverse process; action, abducts cervical vertebrae; nerve supply, lateral part: ventral primary rami of cervical spinal nerves; medial part: dorsal primary rami of cervical spinal nerves. Synonym: musculi intertransversarii posteriores cervicis, posterior cervical intertransverse muscles. (05 Mar 2000) |

| musculi intertransversarii thoracis | Origin, transverse processes of thoracic vertebrae; insertion, next superior transverse process; action, abducts thoracic vertebrae; nerve supply, dorsal primary rami of thoracic nerves. Synonym: musculi intertransversarii thoracis, thoracic intertransverse muscles. (05 Mar 2000) |
| musculi laryngis | The intrinsic muscles that regulate the length, position and tension of the vocal cords and adjust the size of the openings between the aryepiglottic folds, the ventricular folds and the vocal folds. Synonym: musculi laryngis. (05 Mar 2000) |
| musculi levatores costarum | musculus levator costae, elevator muscle of rib, musculi levatores costarum |
| musculi levatores costarum breves | Origin, the transverse processes of last cervical and eleven thoracic vertebrae; insertion ribs immediately below, between angle and tubercle. Synonym: musculi levatores costarum breves. (05 Mar 2000) |
| musculi levatores costarum longi | Insertion, the second rib below their origin; action, raise ribs; nerve supply, intercostal. Synonym: musculi levatores costarum longi. (05 Mar 2000) |
| musculi linguae | The extrinsic muscles include the genioglossus, hyoglossus, chondroglossus, and styloglossus muscles; the intrinsic muscles are the vertical, transverse, and the superior and inferior longitudinal; all are innervated by the hypoglssal nerve. Synonym: musculi linguae. (05 Mar 2000) |
| musculi ossiculorum auditus | The musculus stapedius and musculus tensor tympani. Synonym: musculi ossiculorum auditus. (05 Mar 2000) |
| musculi pectinati | Prominent ridges of atrial myocardium located on the inner surface of much of the right atrium and both auricles. Synonym: musculi pectinati, pectinate fibres. (05 Mar 2000) |
| musculi perinei | Synonym: perineal muscles. (05 Mar 2000) |
| musculi rotatores | Deepest of the three layers of transversospinalis muscles, chiefly developed in the thoracic region; they arise from the transverse process of one vertebra and are inserted into the root of the spinous process of the next two or three vertebrae above; action, traditionally described as a column, it is more likely that these muscles, provided with a very high density of muscle spindles, are organs of proprioception; nerve supply, dorsal primary rami of the spinal nerves. Synonym: musculi rotatores, rotator muscles. (05 Mar 2000) |
| musculi rotatores cervicis | The rotator muscles attached to the cervical vertebrae. Synonym: musculi rotatores cervicis, cervical rotator muscles. (05 Mar 2000) |
| musculi rotatores lumborum | The rotator muscles of the lumbar vertebrae. Synonym: musculi rotatores lumborum, lumbar rotator muscles. (05 Mar 2000) |
| musculi rotatores thoracis | The rotators of the thoracic vertebrae. Synonym: musculi rotatores thoracis, thoracic rotator muscles. (05 Mar 2000) |
| musculi suboccipitales | A group of muscles located immediately below the occipital bone; they are: rectus capitis anterior muscle, rectus capitis posterior major and minor muscles, rectus capitis lateralis musculus, obliquus capitis superior and inferior muscles; innervated by suboccipital nerve; although actions are described, it is held by many authorities that these muscles act primarily as organs of proprioception. Synonym: musculi suboccipitales. (05 Mar 2000) |
