The size of pupil is controlled by thea) ...
The size of the pupil is controlled by the iris muscles. The iris is the colored part of the eye, and it contains two types of muscles - the radial muscles and the circular muscles.
Explanation:
• The diameter of the pupil is controlled by the contraction and relaxation of these muscles.
• The circular muscles, also called the sphincter muscles, are located around the edge of the pupil. When they contract, they cause the pupil to constrict or become smaller, which reduces the amount of light entering the eye.
• The radial muscles, also called the dilator muscles, are located around the outer edge of the iris. When they contract, they cause the pupil to dilate or become larger, which allows more light to enter the eye.
• The iris muscles are controlled by the autonomic nervous system, which is responsible for regulating involuntary actions in the body.
• The size of the pupil can also be affected by external factors such as light, emotions, and medications.
In summary, the iris muscles of the eye, specifically the circular and radial muscles, control the size of the pupil. They work in opposition to each other to regulate the amount of light entering the eye, and are controlled by the autonomic nervous system.
