Structures Of The Retina Flashcards
1

Receive images that have passed through the lens of the eye, which are converted into nerve impulses and transmitted to the brain via optic nerve
2
Q
Rods
A
Black and white receptors
3
Q
Cones
A
Color receptors
4
Q
Macula
A
Macula lutea, clearly defined light-sensitive area in the center of the retina that is responsible for sharp central vision
5
Q
Fovea centralis
A
Pit in the middle of the macula, best in this area bc it contains a high concentration of cones and no rods
6
Q
Optic disk
A
Blind spot, small region in the eye where the nerve endings of the retina enter the optic nerve, does not contain any rods or cones to convert images into nerve impulses
7
Q
Optic nerve
A
Transmit nerve impulses from the retina to the brain
