Cones are concentrated at the center of retina called fovea centralis where no rod cells are present.
The retina is the innermost lining of the eye, made up of thousands of light-sensitive cells, with an inner part of nerve tissue and a pigmented outer part. It plays a fundamental role in the formation of images, which will be projected and then sent to the brain, through electrical impulses.
The retina consists of three types of layers: bipolar neurons, ganglion neurons and photosensitive cells.
Bipolar neurons promote the union of photosensitive cells with ganglion neurons, which are grouped with nerve fibers and thus originate the optic nerve. It carries nerve impulses to the brain. Photosensitive cells, due to their shape, are named in two types: cones and rods.
There are about 6 million cones that are concentrated in a small depression located in the macula lutea (center of the retina) called the fovea. They have an elongated and cylindrical shape, with conical outer segments. It is in this region that the image is most clearly formed, as they are stimulated by the most intense light. Cones are specialized in the accuracy of daytime vision and in recognizing color. There are three types of cones that have fundamental photopigments that respond to light of wavelengths (λ): cyanopigment - S cones (short λ) - sensitive to blue color, chloropigment - M cones (medium λ) - sensitive to green color and erytopigment - cones L (λ long) - sensitive to red color. The brain interprets the signals received by these cones, which allows it to process color differentiation.
<u>Answer</u>:
Cameron has been very stressed during harvest season while working on farm equipment in the evenings and harvesting the crops during the day. He comes down with the flu the day after his last field is harvested. The reason for his illness is likely that Cameron’s stress hormones suppressed the activity of Lymphocytes.
<u>Explanation</u>:
Immune system is the collection of billion number of cells that travel through our bloodstream. They defend our body against bacteria and viruses. White blood cells are the main immune cells in our body.
When a person gets stressed, the immune system's ability to fight gets reduced. The stress hormone “corticosteroid” suppresses the efficiency of the 'immune system' by reducing the number of "Lymphocytes". Lymphocytes are of two types:
a. "B cells" which produce antibodies and are released in the "fluid" surrounding the body cells.
b. "T cells" which gets locked to the 'infected' cell and destroy it.
