| retinal cone | <ophthalmology, physiology> One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, and are differentially sensitive to particular wavelengths of light and therefore important for colour vision. They provide vision with higher spatial and temporal acuity, and it is the combination of signals from cones with different pigments that facilitates colour vision. There are three types of cones, each type sensitive to red, green or blue. Present in large numbers in the fovea. (03 Jul 1999) |

| pi cone monochromatism | Impaired, but not absent, colour vision with less severely reduced visual acuity than in complete achromatopsia; inherited as an autosomal recessive or as an X-linked disorder (blue cone monochromism; pi cone monochromatism ). (05 Mar 2000) |
| cold cone biopsy | <gynaecology, procedure> A procedure which excises a cone of tissue (mucous membrane) off the cervix for purpose of diagnostics and therapeutics (removes precancerous cells). See: cervical dysplasia. (27 Sep 1997) |
| cone | 1. <plant biology> In gymnosperms and club mosses, a group of sporophylls arranged compactly on a central axis, in the angiosperm family Casuarina, a woody multiple fruit incorporating the bracts and bracteoles associated with the flowers. 2. <physiology> The retinal cone responsible for colour vision.

| cone fibre | A part of the cone cell of the retina; the inner cone fibre is a slender axon-like part of the cone extending from the cell body to the pedicle located in the outer plexiform layer of the retina; in the outer fovea, where the cones are much elongated, they narrow to an (05 Mar 2000) |
