What is a conical cell?
A conical cell or simply a "cone" is a specialized cell sensitive cell found in the retina of the eye and is used to discriminate in colors and details. In humans there are three types of conical cells, sensitized to various wavelength ranges to provide a series of color perception. Different organisms have different number of cones, sensitized to different areas of the spectrum, allowing animals such as bees to perceive infrared light while humans cannot. The cone -shaped segment is located at the top of the cell and responds to different wavelengths of light depending on the concentration of the photopigment present in the structure. As this structure reacts, it sends the signal to the main body of the conical cell and the input from the knot cell score is used to create a complete image for the brain. There are over four million conical cells in the eye and especially densely packed in Fovea, the key area of the eye.
these cells are less feelingsLive to light than their rod colleagues. The cells of the rod work in very weak light, but do not respond to color and have a structure similar to a rod. Organisms have different concentrations of rod and cone cells depending on the environment where they developed. Animals that need good vision in settings with weak lighting, such as night animals, have many more rods because these cells are more useful. Animals used for bright light and the necessary color differentiation, such as humans, tend to have an increased number of conical cells, although the bars still exceed the cones.
cones are sensitive to yellowish green, blue purple and green light. When people perceive the scenes in color, they do with the help of millions of these cells, each providing a small piece of puzzle. For example, when cells sensitive to green light, for example, it is an indicator that Persyn looks at something green like a tree. Various light intensity provided rods create shading and selective firing yellow-green cones mIt can reveal new growth, usually lighter green.
People with color vision disorders may have a cone problem, although there are other causes of color. Some people have no cones at all and cannot perceive color, while others have reduced numbers or defective cones, experience impaired color vision. When people are diagnosed with a color stain, tests can be performed to learn more about why they have problems with color vision.
