Ojo Humano Y Sus Partes
The Human Eye and Its Parts
Introduction
The human eye is a complex and fascinating organ that allows us to see the world around us. It is made up of many different parts, each of which plays a specific role in the process of vision.
The Cornea
The cornea is the clear, dome-shaped structure that covers the front of the eye. It is responsible for focusing light on the retina, the light-sensitive tissue at the back of the eye.
The Pupil
The pupil is the black hole in the center of the eye. It is surrounded by the iris, the colored part of the eye. The pupil changes size to control the amount of light that enters the eye.
The Lens
The lens is a transparent structure that sits behind the pupil. It changes shape to focus light on the retina.
The Retina
The retina is the light-sensitive tissue at the back of the eye. It contains millions of photoreceptor cells that convert light into electrical signals.
The Optic Nerve
The optic nerve is a bundle of nerve fibers that carries the electrical signals from the retina to the brain. The brain interprets these signals and creates an image of the world around us.
Other Parts of the Eye
In addition to these major parts, the eye also contains a number of other important structures, including the eyelids, eyelashes, tear ducts, and muscles.
Conclusion
The human eye is a complex and amazing organ that allows us to see the world around us. By understanding the different parts of the eye and how they work together, we can appreciate the incredible gift of sight.
