Does pupil size remain constant while focusing fixed near point object?
Yes, pupil size should not be affected by the focal distance, unless there is a change in the amount of light at that distance. To change focal distance, the lens contracts or expands. The pupil dilates and constricts based upon how much ambient light there is.

What is the function of the prepatellar bursa?
Bursa sacs are both the shock absorbers and the ball bearings of the musculoskeletal system. They disperse forces from blows on bony prominences and reduce friction where tendons or ligaments are in frequent motion. A bursa sac functions as a gliding surface to reduce friction between tissues of the body. The plural of bursa is "bursae". There are 160 bursae in the body. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees.

What change in the eye does accommodation involve?
im sure its when the lens either gets thicker or thinner to focus on near or far things----------------------------------------------------------------Accommodation is when the shape of the lens in the eye changes to make sure that a clear image is still being reflected onto the retina when you're looking at far of near objects.When you look at a near object, a lot of light refraction is needed, so the ciliary muscles contract & the suspensory ligaments slacken so that the shape of the lens becomes fat & rounded.When you look as a far object, not a much light refraction is needed, so the ciliary muscles relax & the suspensory ligaments tighten, allowing the lens to become long & thin.In this way, you continue to see a clear image whether you're looking at something in the distance or something nearby & this is accommodation.
Does the pupil dilate when focusing for near vision?
no it actually constricts. :)
What are the similarities between a camera and a human eye in terms of the method of focusing near and far objects?
no answer
What rhymes with focusing?
A word that rhymes with focused might include locust or unfocused. Words that rhyme often have the same letters near the end of the word.
Where does Timmy Turner live?
California, most likely. [In fairy idol, when they were searching for Chester on this large screen it showed them focusing on an area near California]
What is the definition of reactive to light and accommodation?
Reactive to light refers to pupils constricting when exposed to light and dilating in the dark. Reactive to accommodation means pupils constricting when focusing on near objects and dilating when looking at far objects.
How is the human eye able to see near and far objects clearly?
The human eye has the ability to absorb light that is emitted and reflected from the environment. Visible light rays from some source, such as the Sun or a lamp, are emitted and transmitted. Light is absorbed from any and every object that it touches. That object absorbs the light that the corresponding pigment is able to absorb, such as chlorophyll absorbing red light. That light is absorbed into the eye and is processed to the brain via the optical nerve to create an image. Of course, any eye disorder, such as myopia or astigmatism, hinders the ability for the light to be properly processed and to be seen clearly by the eye.
How does a person get a heel spur?
People can get a heel spur in many different ways. Putting excessive stress on the heel bone, ligaments, and nerves near the heel can cause cause the growing of a heel spur. Running and jogging repeatedly on hard surfaces can also cause the growth of a heel spur.
What is the name of the process in which adjustments are made by the eye to produce a clear image on the retina?
Accommodation is an adjustment, especially adjustment of the eye for seeing objects at various distances. This is accomplished by the ciliary muscle, which controls the lens of the eye, allowing it to flatten or thicken as is needed for distant or near vision.
Can you keep your eyes still?
It is possible to keep the eyes still (or, at least, convince your brain that's what's happening) by sitting in the near-dark and focusing your eyes on a single point. You will notice your vision becoming darker and more blurred, until you can't see anything at all. It is difficult to hold this, though, as the eye has been trained since birth to keep moving, especially in new situations (such as becoming blind in the near-dark).
How do you help a 2 month old baby with collarbone dislocation and why does it happen?
Take it to a chiropractor so they can relocate it. Baby bones are not yet completely hard (ossified) and their ligaments are very lax (loose). It's likely that the baby's arm was pulled too hard causing a dislocation in either the sternoclavicular joint (near the sternum/chest) or the acromioclavicular joint (near the shoulder). A chiropractor is trained to determine the direction of the dislocation and apply the proper force in the correct direction to relocate the joint effectively.
How do bones move together?
The articulation (movement) of a joint is aided by a capsule between the bones (cartilage); and synoval fluid to aid lubrication. The joint will be held together overall by strong bundles of fibre called ligaments; many of them in complex joints such as knee and shoulder. And tendons are strong fibre bundles attaching the muscles to the bones near the joint to actually move the joint.
