| stratum nucleare internum retinae | The intermediate layer of neurons in the retina composed largely of bipolar cells. Synonym: internal nuclear layer of retina, stratum ganglionare retinae, stratum nucleare internum retinae. (05 Mar 2000) |
|---|---|
| stratum pigmenti retinae | The outer layer of the retina, consisting of pigmented epithelium. Synonym: ectoretina, stratum pigmenti bulbi, stratum pigmenti retinae, tapetum nigrum, tapetum oculi. (05 Mar 2000) |
| stratum plexiforme externum et internum retinae | Layer's of the retina where synapses occur; in the external layer, processes of rods and cones synapse with bipolar neuron dendrites; in the internal layer, axon terminals of bipolar cells synapse with ganglion cell dendrites. See: retina. Synonym: stratum plexiforme externum et internum retinae. (05 Mar 2000) |
| striae retinae | Concentric lines on the surface of an abnormal retina. Synonym: Paton's lines. (05 Mar 2000) |
| dialysis retinae | Congenital or traumatic separation of the peripheral sensory retina from the retinal pigment epithelium at the ora serrata, often causing a retinal detachment. Synonym: retinodialysis. (05 Mar 2000) |
| ischemia retinae | Diminished blood supply in the retina due to failure of the arterial circulation; it may occur as a result of arterial embolism or spasm; poisoning, as by quinine; or exsanguination from recurring profuse haemorrhages (e.g., in parturition, gastric and duodenal ulcers, and pulmonary tuberculosis); bilateral transitory or permanent blindness may result. (05 Mar 2000) |
| fovea centralis retinae | A depression in the centre of the macula retinae containing only cones and lacking blood vessels. Synonym: fovea centralis retinae, central pit. (05 Mar 2000) |
| foveola retinae | The central portion of the central retinal fovea that contains cones only. Synonym: foveola ocularis. (05 Mar 2000) |
| arcus pedis longitudinalis pars lateralis | Formed by calcaneus, cuboid and two lateral metatarsals; the combined arch is supported normally by ligaments, intrinsic muscles, and the tendons of extrinsic muscles of the foot. Synonym: arcus pedis longitudinalis pars lateralis. (05 Mar 2000) |
| arcus pedis longitudinalis pars medialis | Formed by the calcaneus, talus, navicular, three cuneiform bones, and the three medial metatarsals. Synonym: arcus pedis longitudinalis pars medialis. (05 Mar 2000) |
| pars | A part; a portion. Origin: L. Pars (part-) a part (05 Mar 2000) |
| pars abdominalis aortae | <anatomy> The largest arterial conduit below the diaphragm. This term refers to the portion of the aorta below the diaphragm to the bifurcation into the right and left common iliac arteries. It supplies blood to the abdominal viscera, pelvic organs and lower extremities. (20 Jun 2000) |
| pars abdominalis ductus thoracici | The part of the thoracic duct between the cisterna chyli and the aortic hiatus of the diaphragm. Synonym: pars abdominalis ductus thoracici. (05 Mar 2000) |
| pars abdominalis oesophagi | The part of the oesophagus inferior to the diaphragm. See: oesophagus. Synonym: pars abdominalis oesophagi. (05 Mar 2000) |
| pars abdominalis ureteris | The part of the ureter between the renal pelvis and the brim of the pelvis. Synonym: pars abdominalis ureteris. (05 Mar 2000) |
