What is the sequence of reactions when a person looks at a distant object?
The sequence of reactions when a person looks at a distant object is pupils dilate, ciliary zonule, becomes taut, and lenses become less convex. During embryonic development the lens of the eye forms from the surface ectoderm overlying the optic cup.
What is shortening of eye ball?
The shorting of an eyeball, or pupil, is called a dialation. This happens when a pupil comes into contact with light. It becomes smaller to let less light in, make your vision clearer, and protect your eye. When a room gets darker, your pupils become larger. This is because there is less light, and to get a clearer picture your eyes need more light. This is a reason for UV protected sunglasses because if they arn't protected your pupils will get bigger and allow UV Rays to get in and harm your eyes.(Tid-bit Sorry) Anyway, the shortening of hrinking of an eyeball is a dialation.
Does the pupil get smaller when you are under the influence when a flashlight is shined in it than when not under the influence?
Yes, drug use can affect the size of the pupil. Some drugs can cause pupils to constrict (get smaller) while others can dilate (get larger) compared to when not under the influence. It's important to note that different drugs can have varying effects on pupil size.
When the light is bright the iris open so the pupil become?
Smaller.
Dark in color and is the hole in the colored part of the eye?
The dark center of the colored part of the eye is called the pupil. It appears this way because it controls the amount of light that enters the eye by dilating or constricting.
What happens to the pupil when the eye focuses on distant objects?
The pupils' size change in response to the degree of light that is entering the. Dilation depends less on the distance of the object from the eye and more on how many light rays are in the field of vision.
What happened to the pupil as the object get closer?
the pupil becomes smaller trying to converge the light coming from the object.
What is the sequence of reactions when a person looks at a distant object?
The sequence of reactions when a person looks at a distant object is pupils dilate, ciliary zonule, becomes taut, and lenses become less convex. During embryonic development the lens of the eye forms from the surface ectoderm overlying the optic cup.
What happens to light rays after they enter the pupil?
They die.
What happens to your pupil when in a light room?
it gets bigger
What happens if the pupil doesn't work?
If the pupil of the eye did not work, than your eye could not regulate light entering it.
What happens to the lensecornea and pupil when lights hits it?
Nothing. AFTER the light is detected and calibrated, the pupil may change size.
Could you ever see the pupil in your own eye?
literally speaking the pupil is just a hole, so no. But by looking in a mirror you can perceive the pupil as a black circle in the middle of the iris.
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.
How do you compare the shape of the pupil in the dissected eye with your own pupil?
You can compare the shape of a human eye pupil to that of a cow eye pupil by means of comparing and locating the iris. The iris of a cow is brown where as the iris of a human has multiple colors.
How do you compare the shape of the pupil in the dissected eye with your own?
by looking at it.
What is an Argyll Robertson pupil?
An Argyll Robertson pupil is a bilateral small pupil of the eye which reduces in size when the patient focuses on a near object but does not constrict when exposed to bright light - a sign of neurosyphilis.
