What region of the retina lacks photoreceptors cells quizlet?

What region of the retina lacks photoreceptors cells quizlet?

The blind spot of the eye is the optic disc.It is the part oft he retina where the optic nerve exits the eye, and it blind because it is a region of the retina that lacks photoreceptors.

What part of the retina contains only photoreceptors?

fovea

What layer of the eye contains photoreceptors?

Retina

Are there rods in the fovea?

The increased density of cones in the fovea is accompanied by a sharp decline in the density of rods. In fact, the central 300 xb5m of the fovea, called the foveola, is totally rod-free.

Which region of the retina lacks photoreceptor cells?

blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area.

What area of the retina is lacking photoreceptors and is referred to as the blind spot quizlet?

Fovea Centralis. region of the sharpest vision. Optic Disc. where nerve fibers leave the eye, creating the blind spot (lacks photoreceptors)

What structure subdivides the eye into the anterior and posterior cavities?

iris

Why does the blind spot lack photoreceptors quizlet?

What is the path of light through the eye? The optic disc is called the blind spot because it lacks photoreceptors so light focused on it cannot be seen. This is where the ganglion cell axons form the optic nerve, which exits via the optic disc.

What part of the retina has photoreceptors?

Rod and cone photoreceptors are found on the outermost layer of the retina; they both have the same basic structure. Closest to the visual field (and farthest from the brain) is the axon terminal, which releases a neurotransmitter called glutamate to bipolar cells.

Where are the photoreceptors of the eye found?

the retina

What part of the retina does not contain any photoreceptors?

blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area.
