| diaphragm sellae | A fold of dura mater extending transversely across the sella turcica and roofing over the hypophyseal fossa; it is perforated in its centre for the passage of the infundibulum. Synonym: diaphragma sellae, diaphragm sellae, tentorium of hypophysis. (05 Mar 2000) |

| inferior fascia of pelvic diaphragm | The fascia that covers the inferior aspect of the levator ani and coccygeus muscles. Synonym: fascia diaphragmatis pelvis inferior, anal fascia. (05 Mar 2000) |
| inferior fascia of urogenital diaphragm | The layer of fascia extending between the ischiopubic rami inferior to the sphincter urethrae and the deep transverse perineal muscles. Synonym: membrana perinei, fascia diaphragmatis urogenitalis inferior, Camper's ligament, ligamentum triangulare, perineal membrane, triangular ligament. (05 Mar 2000) |
| iris diaphragm | <microscopy> A diaphragm with thin metal leaves so arranged that the rotation of an actuating lever varies the diameter. (05 Aug 1998) |
| eventration of the diaphragm | Extreme elevation of a half or part of the diaphragm, which is usually atrophic and abnormally thin. (05 Mar 2000) |
| urogenital diaphragm | A triangular sheet of muscle between the ischiopubic rami; composed of the sphincter urethrae, and the deep transverse perineal muscles. Synonym: diaphragma urogenitale. (05 Mar 2000) |
| field diaphragm | <microscopy> In a photomicrographic system particularly, an iris diaphragm that is imaged in the field of view with Kohler illumination. This limits the extent of the illuminated field and eliminates much extraneous light. The iris diaphragm that is located in front of the collecting lens of the light source. With Kohler illumination, the condenser focuses the image of the field diaphragm onto the image plane. (05 Aug 1998) |
| left crus of diaphragm | The muscular origin of the diaphragm from the upper two or three lumbar vertebrae that ascends to the left of the aorta to reach the central tendon. Synonym: crus sinistrum diaphragmatis. (05 Mar 2000) |
| lumbar part of diaphragm | The portion of the diaphragm that arises from the upper lumbar vertebrae and from the medial and lateral arcuate ligaments. See: right crus of diaphragm, left crus of diaphragm, lateral arcuate ligament, medial arcuate ligament. Synonym: pars lumbalis diaphragmatis, vertebral part of diaphragm. (05 Mar 2000) |
| abdominothoracic arch | A bell-shaped line defined by the lower end of the sternum and the costal arches on each side, constituting a boundary line between the anterolateral portions of the thoracic and abdominal walls. (05 Mar 2000) |
| alveolar arch of mandible | The free margin of the alveolar process of the mandible. Synonym: arcus alveolaris mandibulae, limbus alveolaris. (05 Mar 2000) |
| alveolar arch of maxilla | The free border of the alveolar process of the maxilla. Synonym: arcus alveolaris maxillae, limbus alveolaris. (05 Mar 2000) |
| anterior arch of atlas | An arch that connects the lateral masses of the atlas anteriorly and articulates with the anterior articular facet of the dens of the axis. Synonym: arcus anterior atlantis. (05 Mar 2000) |
| anterior palatine arch | One of a pair of ridges or folds of mucous membrane passing from the soft palate to the side of the tongue; it encloses the palatoglossus muscle and forms anterior margin of the tonsillar fossa. Also demarcates oral cavity from isthmus of fauces. Synonym: arcus palatoglossus, anterior palatine arch, anterior pillar of fauces, arcus glossopalatinus, glossopalatine arch, glossopalatine fold. (05 Mar 2000) |
| aortic arch | The curved portion between the ascending and descending parts of the aorta; it begins as a continuation of the ascending aorta posterior to the sternal angle, runs posteriorly and slightly to the left as it passes over the root of the left lung, and becomes the descending aorta as it reaches and begins to course along the vertebral column; it gives rise to the brachiocephalic trunk, the left common carotid and left subclavian arteries. Any member of the several pairs of arterial channels encircling the embryonic pharynx in the mesenchyme of the brachial arches; there are potentially six pairs, but in mammals the fifth pair is poorly developed or absent. The first and second pairs are functional only in very young embryos; the third pair is involved in the formation of the carotids; the fourth arch on the left is incorporated in the arch of the aorta; the sixth pair forms the proximal part of the pulmonary arteries. A series of arterial channels encircling the embryonic pharynx in the mesenchyme of the branchial arch's. There are potentially six pairs, but in mammals the fifth pair is poorly developed or absent. The first and second pairs are functional only in very young embryos; the third pair is involved in the formation of the carotids; the fourth arch on the left is incorporated in the arch of the aorta; the sixth pair forms the proximal part of the pulmonary arteries. Synonym: arcus aortae. (05 Mar 2000) |
