Sentences with phrase «called rod photoreceptors»

Not exact matches

A healthy retina usually features light - sensitive cells — photoreceptors — called cones and rods.

Genetic defects cause photoreceptor degeneration, which are majorly classified into rod - cone dystrophy called retinitis pigmentosa (rods initially degenerate, followed by cone degeneration), cone - rod dystrophy (cone degeneration, followed by rod degeneration), and Leber congenital amaurosis (LCA).

Behind the photoreceptors is another layer of cells called retinal pigment epithelium (RPE), which support the rods and cones by delivering nutrients from the bloodstream and removing waste that the rods and cones generate.

The macula is densely packed with photoreceptor cells called rods and cones that react to light and send electrical nerve impulses to the optic nerve and into the brain.
