| strap muscles | The small, flat muscles inferior to the hyoid bone including the sternohyoid, omohyoid, sternothyroid, thyrohyoid, and levator muscle of the thyroid gland. Synonym: musculi infrahyoidei, strap muscles. (05 Mar 2000) |
|---|---|
| suboccipital muscles | 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) |
| superficial back muscles | Muscles originating from the vertebral column and having their fleshy bellies located in the back, but inserting onto the appendicular skeleton of the upper limb or the ribs. They are not innervated by dorsal primary rami of spinal nerves, as are the deep or true muscles of the back; includes the trapezius muscle (innervated by spinal accessory nerve) and latissimus dorsi, rhomboids, levator scapulae, and thoracic muscles (innervated by ventral primary rami of spinal nerves, or derivatives thereof). (05 Mar 2000) |
| superior retinaculum of extensor muscles | The ligament that binds down the extensor tendons proximal to the ankle joint; it is continuous with (a thickening of) the deep fascia of the leg. Synonym: retinaculum musculorum extensorum superius, ligamentum transversum cruris, superior retinaculum of extensor muscles, transverse crural ligament, transverse ligament of leg. (05 Mar 2000) |
| deep muscles of back | Muscles of the back innervated by the dorsal primary rami of spinal nerves; includes erector spinae, transversospinalis, interspinal, and intertransverse muscles; excludes the superficial back muscles which are appendicular and are innervated by ventral rami, and the trapezius, innervated by the spinal accessory nerve. Synonym: true muscles of back. (05 Mar 2000) |
| suprahyoid muscles | The group of muscles attached to the upper part of the hyoid bone including the digastric, stylohyoid, mylohyoid, and geniohyoid muscles. Synonym: musculi suprahyoidei. (05 Mar 2000) |
| synergistic muscles | Muscle's having a similar and mutually helpful function or action. (05 Mar 2000) |
| dorsal interosseous muscles of foot | Four muscles in the foot; origin, from sides of adjacent metatarsal bones; insertion, first into medial, second into lateral side of proximal phalanx of second toe, third and fourth into lateral side of proximal phalanx of third and fourth toes; action, abduct toes 2-4 from an axis through the second toe; nerve supply, lateral plantar. Synonym: musculi interossei dorsalis pedis. (05 Mar 2000) |
| dorsal interosseous muscles of hand | Four muscles in the hand; origin, sides of adjacent metacarpal bones; insertion, proximal phalanges and extensor expansion, first on radial side of index, second on radial side of middle finger, third on ulnar side of middle finger, fourth on ulnar side of ring finger; action, abduct fingers 2-4 from the axis of the middle finger, nerve supply, ulnar. Synonym: musculi interossei dorsalis manus. (05 Mar 2000) |
| dorsal muscles | The muscles of the back in general, including those attaching the shoulder girdle to the trunk posteriorly, the posterior serratus muscles, and the erector spinae. Synonym: musculi dorsi, dorsal muscles. (05 Mar 2000) |
| inferior retinaculum of extensor muscles | A Y-shaped ligament restraining the extensor tendons of the foot distal to the ankle joint. Synonym: retinaculum musculorum extensorum inferius, cruciate ligament of leg, inferior retinaculum of extensor muscles, ligamentum cruciatum cruris. (05 Mar 2000) |
| infrahyoid muscles | The small, flat muscles inferior to the hyoid bone including the sternohyoid, omohyoid, sternothyroid, thyrohyoid, and levator muscle of the thyroid gland. Synonym: musculi infrahyoidei, strap muscles. (05 Mar 2000) |
| intermediate layer of the transversospinalis muscles | <anatomy, muscle> Origin, from the sacrum, sacroiliac ligament, mamillary processes of the lumbar vertebrae, transverse processes of thoracic vertebrae, and articular processes of last four cervical vertebrae; insertion, into the spinous processes of all the vertebrae up to and including the axis; action, rotates vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus multifidus, intermediate layer of the transversospinalis muscles, musculus multifidus spinae. (05 Mar 2000) |
| interosseous muscles | Muscles which arise from and run between the long (metacarpal and metatarsal) bones of the hand and foot, extending to and producing movement of the digits. See: dorsal interosseous muscles of foot, dorsal interosseous muscles of hand, palmar interosseous muscle, plantar interosseous muscle. Synonym: musculi interossei. (05 Mar 2000) |
| interspinales muscles | The paired muscles between spinous processes of adjacent vertebrae; subdivided into cervical, thoracic, and lumbar muscles. Synonym: musculi interspinales, interspinal muscles. (05 Mar 2000) |
