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.
The speaker of the house is in front of the house of representatives. She usually does not preside over the debates personally, instead she delegates this function to another member of the majority party´s chamber. In addition to presiding over the chamber, she has administrative and procedural functions and remains a Representative of his own district.
It occupies second place in the line of presidential succession, after vice presidency of the United States, which also assumes <em>ex officio </em>the presidency <em>pro tempore </em>of the senate. It is a similar charge to the election of a prime minister in a parliamentary regime.
Answer:
D. The course altered Gary's concept of psychological disorder
Explanation:
branch of psychology concerned with mental processes (as perception, thinking, learning, and memory) especially with respect to the internal events occurring between sensory stimulation and the overt expression of behavior. So based on the question from a congnitive psychologist view of point, Gary expectations were dashed after the course hence leading to an internal reaction that changes his perception of psycological disorder.
