the iris
The iris, specifically the muscles within it, control the size of the pupil. Contraction and relaxation of these muscles regulate the amount of light entering the eye by adjusting the diameter of the pupil.
The Iris contains the muscles that control Pupil size.
The colored muscular diaphragms that surround the pupil are called the iris. They control the size of the pupil to regulate the amount of light entering the eye.
No. The pupil can only open to the size of the iris.
It's called the iris.
The iris is the layer that surrounds the pupil and controls the size and diameter of the pupil. It also controls the amount of light that reaches the pupil.
The opening that is controlled by the muscles of the iris is called the pupil. The iris is responsible for adjusting the size of the pupil in response to different lighting conditions.
it is known as Iris. contraction or relaxation of iris alters the size of pupil.
The visible colored part of the eye that controls pupil dilation is the iris. The iris regulates the size of the pupil in response to light conditions and helps to control the amount of light that enters the eye.
iris
Retina- light image is focused on the retina, and it contains the photosensitive receptor cells Pupil- the opening of the eye. The size of the opening is regulated by the iris Iris- pigmented part of the eye (gives people their eye color). The iris is composed of smooth muscle and controlled by reflex.
When the radial muscles of the iris contract, the pupil dilates or becomes larger.
