What is the function of the pupil? What function does the optic nerve have? What is the function of the optic nerve? What structure of the eye keeps the cornea lubricated? What is the function of the iris? What structure of the eye takes nutrients to the lens and cornea?
The pupil is the circular opening that allows light to enter the eye. It is found at the center of an eye structure called the iris, which is ring-shaped and causes differences in eye color between individuals. The pupil functions as an opening that allows light through the lens, which ...
In human anatomy, the iris is the colored, muscular part of the eye surrounding the pupil. The iris is in front of the lens and behind the cornea and is bathed in front and behind by a fluid known as the aqueous humor.
Pupillary autonomic dysfunction and right-left differences were investigated in muscle contraction headache (MCH) and migraine, by means of biocular infrared video pupillography (biocular Iriscorder). The study was performed on 36 patients with MCH or migraine and on 23 healthy controls. The pupil...
It protects the pupil, the iris, and the inside of the eye from penetration by foreign bodies and is the first and most powerful element in the eye’s focusing system. As light passes through the cornea, it is partially refracted before reaching the lens. The curvature of the cornea, ...
The primary function of the eye lens is to bend the light to focus it on the retina. Light enters the cornea when the eye is open. The pupil and iris control how much light enters the eye and passes through to the lens. The lens works like a curved lens in a camera, allowing for...

and preganglionic sympathetic and parasympathetic nuclei37,38,39,40. LC controls pupil dilation by inhibiting the preganglionic parasympathetic neurons located in the nucleus of Edinger-Westphal41,42,43,44, which innervates the iris sphincter muscle responsible for pupil dilation36,45. Although also...
