| choroid plexus papilloma | <radiology> Isodense or hyperdense enhancing mass, location: usually atrium of lateral ventricle, age: usually less than 10 yrs, complications: non-obstructive hydrocephalus (12 Dec 1998) |
|---|---|
| choroid skein | A marked enlargement of the choroid plexus of the lateral ventricle at the junction of the central part with the inferior horn. Synonym: glomus choroideum, choroid skein. (05 Mar 2000) |
| choroid tela of fourth ventricle | The sheet of pia mater covering the lower part of the ependymal roof of the fourth ventricle. Synonym: tela choroidea ventriculi quarti, tela choroidea inferior. (05 Mar 2000) |
| choroid tela of third ventricle | A double fold of pia mater, enclosing subarachnoid trabeculae, between the fornix above and the epithelial roof of the third ventricle and the thalami below; at each lateral margin is a vascular fringe projecting into the choroidal fissure of the lateral ventricle; on its undersurface are several small vascular projections filling the folds of the ependymal roof of the third ventricle. Synonym: tela choroidea ventriculi tertii, tela choroidea superior, triangular lamella, velum interpositum, velum triangulare. (05 Mar 2000) |
| choroid veins of eye | Several veins (usually four) from the vascular tunic formed of veins accompanying the posterior ciliary arteries and the ciliary body; then drain into the superior or inferior ophthalmic vein. Synonym: venae vorticosae, venae choroideae oculi, choroid veins of eye, Stensen's veins, vasa vorticosa, vorticose veins. (05 Mar 2000) |
| gyrate atrophy of choroid and retina | A slowly progressive atrophy of the choriocapillaris, pigmentary epithelium, and sensory retina, with irregular confluent atrophic areas and an associated ornithinuria; autosomal recessive inheritance; due to a deficiency of ornithine d-aminotransferase. (05 Mar 2000) |
| coloboma of choroid | A congenital defect of the choroid and retinal pigment epithelium exposing the sclera; the defect is usually situated below the optic disk in the region of foetal fissure. (05 Mar 2000) |
| plexus of choroid artery | <anatomy, artery> An autonomic plexus accompanying the artery of the same name, derived from the internal carotid plexus. Synonym: plexus arteriae choroideae. (05 Mar 2000) |
| superior choroid vein | <anatomy, vein> A tortuous vein that follows the choroid plexus of the lateral ventricle and unites with the superior thalamostriate vein and the anterior vein of the transparent septum to form the internal cerebral vein. Synonym: vena choroidea superior. (05 Mar 2000) |
| inferior choroid vein | <anatomy, vein> A small vein draining the lower part of the choroid plexus of the lateral ventricle into the basal vein. Synonym: vena choroidea inferior. (05 Mar 2000) |
| epithelial choroid layer | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| acoustic nerve diseases | Diseases of the eighth cranial nerve. These include vestibular neuronitis, cochlear neuritis and acoustic neuroma. (12 Dec 1998) |
| adaptation diseases | Disease's falling theoretically into Selye's concept of the general-adaptation syndrome. (05 Mar 2000) |

| agricultural workers' diseases | Diseases in persons engaged in cultivating and tilling soil, growing plants, harvesting crops, raising livestock, or otherwise engaged in husbandry and farming. The diseases are not restricted to farmers in the sense of those who perform conventional farm chores: the heading applies also to those engaged in the individual activities named above, as in those only gathering harvest or in those only dusting crops.
