Where are the light receptors located in the eye?
Light receptors are located in retina of eye ball. They are rods and cones. Rods are for night vision and cones for color vision. Retina is innermost layer in an eye in posterior compartment. Inside it, is vitreous gel. It is a part of brain and gets separate blood supply from branch of internal carotid artery. They are present in large number in fovea centralis. They are absent, where the optic nerve leaves the eye ball. That creates the 'blind spot' in visual area.
Can the fovea centralis be seen with an ophthalmoscope?
Yes. The fovea centralis can be seen with an ophthalmoscope.
Where is the exact location of the cones in the retina?
The cones are the sensory receptors responsible for picking up light of different wavelengths and therefore colours. These are concentrated in an area of the retina called the macular lutea in particular in a pit called the fovea.
Where are photoreceptors highly concentrated?
The fovea centralis has the highest concentration of photoreceptors. The macula lutea has the second highest concentration.
How many rods are located in the human fovea?
22
What Does the fovea contain?
If you can then please specify about which FOVEA are you referring to? because there is... Fovea centralis Trochlear fovea Submandibular fovea Sublingual fovea Pterygoid fovea.. etc..
What is the fovea?
The fovea is a pit in the macula of the eye

Tiny pit in the macula lutea?
The pit in the middle of the macula is called the fovea. The fovea is responsible for high resolution vision.
In what area of the retina are cones concentrated?
The highest concentration of cones is in the macula. The fovea centralis, at the center of the macula, contains only cones and no rods. The macula is a small, yellowish central portion of the retina. It is about 5.5 mm in diamter and is the area providing the clearest vision.
What is the area of sharpest vision in the eye?
Fovea centralis at the Macula. it is so because it contains receptor cells known as the Rods & Cones.Fovea centralis
Can the fovea centralis be seen with an ophthalmoscope?
Yes. The fovea centralis can be seen with an ophthalmoscope.

What is the highest concentration of cones in the eye?
The highest concentration of cones in the retina is 50 per 100 micrometers in the central fovea. (from wikipedia) So there are approximately 17,500 cones in central fovea.
Why is it an advantage for fovea to focus on something colorful?
It is important for the fovea to focus on something colorful because this is where most of color perception occurs. The fovea is small dimple located in the middle of the retina.
Do dogs have a fovea in their eyes?
no
What is the region of the retina where images are focused called?
The region on the retina that humans and other predatory animals have where images are focused is called the fovea centralis.
