| leopard | <zoology> A large, savage, carnivorous mammal (Felis leopardus). It is of a yellow or fawn colour, with rings or roselike clusters of black spots along the back and sides. It is found in Southern Asia and Africa. By some the panther (Felis pardus) is regarded as a variety of leopard. Hunting leopard. See Cheetah. <zoology> Leopard cat any one of several species or varieties of small, spotted cats found in Africa, Southern Asia, and the East Indies; especially, Felis Bengalensis. Leopard marmot. See Gopher. Origin: OE. Leopart, leparde, lebarde, libbard, OF. Leopard, liepart, F. Leopard, L. Leopardus, fr. Gr.; lion + pard. See Lion, and Pard. Source: Websters Dictionary (01 Mar 1998) |

| leopard syndrome | <syndrome> An autosomal dominant inherited disorder characterised by freckle-like spots (lentigines) on the trunk. Other findings may include wide set eyes, sternum abnormalities, prominent ears, deafness, cafe-au-lait spots, pulmonary stenosis, cryptorchidism, delayed puberty or hypogonadism. There is no treatment available only underlying management of each problem. Inheritance: autosomal dominant. (27 Sep 1997) |
| ganglion cells of retina | The nerve cell's of the retina whose central processes (fibres) form the optic nerve; their peripheral processes synapse with the bipolar cell's and through them with the rod and cone cell's; these cell bodies are round or flask-shaped and vary considerably in size. (05 Mar 2000) |
| ganglionic layer of retina | 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) |
| medial arteriole of retina | An arteriole supplying the part of the retina between the optic disk and the macula. Synonym: arteriola medialis retinae. (05 Mar 2000) |
| medial venule of retina | The small vein that passes from the part of the retina between the macula and the optic disk to join the central vein. Synonym: venula medialis retinae. (05 Mar 2000) |
| central artery of retina | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
| central vein of retina | Formed by union of the retinal veins and accompanies the artery of the same name in the optic nerve. Synonym: vena centralis retinae. (05 Mar 2000) |
| cerebral layer of retina | The internal layer of the retina containing the neural elements, as distinguished from the outer leaf of the retina, or pigmented layer. Synonym: pars optica retinae, neural layer of retina, optic part of retina, stratum cerebrale retinae. (05 Mar 2000) |
| retina | Light sensitive layer of the eye. In vertebrates, looking from outside, there are four major cell layers: (i) the outer neural retina, which contains neurons (ganglion cells, amacrine cells, bipolar cells) as well as blood vessels, (ii) the photoreceptor layer, a single layer of rods and cones, (iii) the pigmented retinal epithelium (PRE or RPE), (iv) the choroid, composed of connective tissue, fibroblasts and including a well vascularised layer, the chorio capillaris, underlying the basal lamina of the PRE. Behind the choroid is the sclera, a thick organ capsule. In molluscs (especially cephalopods such as the squid) the retina has the light sensitive cells as the outer layer with the neural and supporting tissues below. See: retinal rods, retinal cones, rhodopsin. (18 Nov 1997) |

| granular layers of retina | The outer nuclear layer, layer 4, of the retina, neuroepithelial layer of retina, and the inner layer, layer 6, of the retina, ganglionic layer of retina. Synonym: granular layers of retina, stratum nucleare externum et internum retinae. (05 Mar 2000) |
