| PPRF | Pontine Paramedian Reticular Formation |
| RAS | 1) Reticular Activating(Activation) System 2) Renal Artery Stenosis |
| reticular nucleus of thalamus | A sheet of fairly large neurons covering the lateral, ventral, and rostral surfaces of the thalamus; its reticular appearance is caused by the numerous fascicles of the thalamic peduncles which traverse the nucleus The nucleus receives numerous fibres from the cerebral cortex but it has no cortical projection. Synonym: nucleus reticularis thalami. (05 Mar 2000) |
|---|---|
| reticular substance | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| reticular tissue | Retiform tissue, a tissue in which the argyrophilic collagenous fibres form a network and that usually has a network of reticular cells associated with the fibres. (05 Mar 2000) |
| primitive reticular cell | A cell with processes making contact with those of other similar cell's to form a cellular network; along with the network of reticular fibres, the reticular cell's form the stroma of bone marrow and lymphatic tissues. (05 Mar 2000) |
| epithelial reticular cell | One of the many-branched epithelial cell's that collectively form the supporting stroma for lymphocytes in the thymus; believed to produce thymosin and other factors that control thymic function. (05 Mar 2000) |
| lateral reticular nucleus | A group of cells in the medulla oblongata, located between the inferior olive and the descending trigeminal nucleus, receiving fibres from the spinal cord and motor cortex and projecting to the cerebellum. Synonym: nucleus lateralis medullae oblongatae, lateral reticular nucleus. (05 Mar 2000) |
| anterior epithelium of cornea | The stratified squamous epithelium covering the outer surface of the cornea; it is smooth, consists usually of five layers of cells, and contains numerous free nerve endings. Synonym: epithelium anterius corneae. (05 Mar 2000) |
| anterior limiting layer of cornea | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| anterior surface of cornea | The external surface of the cornea. Synonym: facies anterior corneae. (05 Mar 2000) |
| marginal ring ulcer of cornea | A slowly advancing intermittent ulcer involving the circumference of the corneal margin. (05 Mar 2000) |
| vertex of cornea | The central part of the cornea, slightly thinner than the peripheral part. Synonym: vertex corneae. (05 Mar 2000) |
| meridian of cornea | Any line bisecting the cornea through its apex. (05 Mar 2000) |
| ring ulcer of cornea | Inflammation of the greater part or the whole of the corneal periphery. (05 Mar 2000) |
| conical cornea | Cone-shaped cornea with the apex of the cone being forward. Also called conical cornea. (12 Dec 1998) |
| cornea | <anatomy, ophthalmology> The transparent structure forming the anterior part of the fibrous tunic of the eye. It consists of five layers: 1. The anterior corneal epithelium, continuous with that of the conjunctiva. 2. The anterior limiting layer (Bowman's membrane). 3. The substantia propria or stroma. 4. The posterior limiting layer (Descemet's membrane). 5. The endothelium of the anterior chamber. Synonym: keratoderma. Origin: L. Corneus = horny (18 Nov 1997) |
