| ES | Erector spinae |
|---|
| musculus erector spinae | Origin, from sacrum, ilium, and spines of lumbar vertebrae; it divides into three columns, iliocostalis musculus, longissimus musculus, and spinalis musculus, which insert into ribs and vertebrae with additional muscle slips joining the columns at successively higher levels; action, extends vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus erector spinae, erector muscle of spine, musculus sacrospinalis. (05 Mar 2000) |
|---|---|
| musculus multifidus spinae | <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) |
| spinae palatinae | The longitudinal ridges along the palatine grooves on the inferior surface of the palatine process of the maxilla. Synonym: spinae palatinae. (05 Mar 2000) |
| erector spinae muscles | Origin, from sacrum, ilium, and spines of lumbar vertebrae; it divides into three columns, iliocostalis musculus, longissimus musculus, and spinalis musculus, which insert into ribs and vertebrae with additional muscle slips joining the columns at successively higher levels; action, extends vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus erector spinae, erector muscle of spine, musculus sacrospinalis. (05 Mar 2000) |
| angulus mandibulae | <anatomy> The angle formed by the lower margin of the body and the posterior margin of the ramus of the mandible. Synonym: angulus mandibulae, angle of jaw. (05 Mar 2000) |
| arcus alveolaris mandibulae | The free margin of the alveolar process of the mandible. Synonym: arcus alveolaris mandibulae, limbus alveolaris. (05 Mar 2000) |
| basis mandibulae | The rounded inferior border of the body of the mandible. Synonym: basis mandibulae. (05 Mar 2000) |
| biventer mandibulae | <anatomy> One of the suprahyoid group of muscles consisting of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin, by posterior belly from the digastric groove medial to the mastoid process; insertion, by anterior belly into lower border of mandible near midline; action, elevates the hyoid when mandible is fixed; depresses the mandible when hyoid is fixed; nerve supply, posterior belly from facial, anterior belly by nerve to the mylohyoid from the mandibular division of trigeminal, a muscle with two fleshy bellies separated by a fibrous insertion. Synonym: musculus digastricus, biventer mandibulae, musculus biventer mandibulae, two-bellied muscle. (05 Mar 2000) |
| canalis mandibulae | The canal within the mandible that transmits the inferior alveolar nerve and vessels. Its posterior opening is the mandibular foramen. Synonym: canalis mandibulae, inferior dental canal. (05 Mar 2000) |
| caput mandibulae | The expanded articular portion of the condylar process of the mandible. Synonym: caput mandibulae. (05 Mar 2000) |
| ramus mandibulae | The upturned perpendicular extremity of the mandible on either side; it gives attachment on its lateral surface to the masseter muscle. Synonym: ramus mandibulae. (05 Mar 2000) |
| ramus marginalis mandibulae nervi facialis | <anatomy, nerve> Branch of facial nerve which parallels the mandibular margin innervating risorius muscle and muscles of lower lip and chin. Synonym: ramus marginalis mandibulae nervi facialis. (05 Mar 2000) |
| pars alveolaris mandibulae | The portion of the body of the mandible that surrounds and supports the lower teeth. Synonym: pars alveolaris mandibulae. (05 Mar 2000) |
| collum mandibulae | The constricted portion of the condylar process below the head of the mandible. Synonym: collum mandibulae. (05 Mar 2000) |
| musculus biventer mandibulae | <anatomy> One of the suprahyoid group of muscles consisting of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin, by posterior belly from the digastric groove medial to the mastoid process; insertion, by anterior belly into lower border of mandible near midline; action, elevates the hyoid when mandible is fixed; depresses the mandible when hyoid is fixed; nerve supply, posterior belly from facial, anterior belly by nerve to the mylohyoid from the mandibular division of trigeminal, a muscle with two fleshy bellies separated by a fibrous insertion. Synonym: musculus digastricus, biventer mandibulae, musculus biventer mandibulae, two-bellied muscle. (05 Mar 2000) |
