|retinal cone||medical dictionary| 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) |Bookmark with:||word visualiser||Go and
