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.
Answer:
<u>Perception </u> is a three phase process of selecting, organizing and interpreting information, objects, people, events or situations.
Explanation:
Perception involves three steps.
1. Selecting
In the first stage we select that stimuli which attracts us the most by ignoring the others about making perception about any event or object.
2. Organizing
In the second stage we organize the information about our selection.
3. Interpretation
In the third step we interpret that information in a meaningful way that makes sense to us.
Answer: The answer is A. Bodily-kinesthetic
Explanation: Bodily-kinesthetic is a type of intelligence whereby you are adept at coordinating your body movement. People with this type of intelligence like to engage in physical activities and have more than average motor skills. They are usually into sports and dancing or whatever form of creative activities that involve presenting ideas with body movement.
Hence, why Lauren does well in the sporting activities mentioned above.
The existing educational system should put more emphasis on creating new competences for healthcare providers in order to enhance nurses' abilities in workflow analysis and redesign.
The implementation of a unique EHR that will train nurses for the actual technology used in hospitals is recommended by Karl and Schubert. The emphasis of the programs should be on using such systems in practice and easing nurses' concerns about using technology.
Students that utilize an academic version of an EHR, for instance, will have more confidence in the workplace as a result of their experience.
The effectiveness of workflow redesign, a crucial component and byproduct of the use of EHRs, is heavily reliant on the qualifications and skills of nurses. In order to increase their level of readiness, healthcare workers should be given the opportunity to practice through learning.
