- You can reheat leftover meat in the oven, on the stove or in the microwave. The trick to keeping it moist is to choose the best method for the type of meat. In many cases, adding a small amount of oil or liquid during the reheating process can prevent meat from drying out.

What Is the Function of the Lens? The two main functions of the lens of the eye are  to focus light onto the retina and to help the eye focus on objects at various distances. The lens of the eye is a rubbery, jellylike structure. It is located behind the cornea and is held in place by tendons that are attached to a set of muscles called ciliary muscles.

Fovea centralis The fovea centralis (the term fovea comes from the Latin, meaning pit or pitfall) is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.he parafovea extends to a radius of 1.25 mm from the central fovea, and the perifovea is found at a 2.75 mm radius from the fovea centralis.

Eye The fovea is an important region of the retina, as it contains the highest concentration of photoreceptors in the eye. Nervous tissue in the retina is connected to the brain through the optic nerve, which passes through a hole in the choroid and sclera in the posterior of the eye.he fibrous tunic forms the outermost layer of the eye and is instrumental in protecting its delicate inner tissues. 1  Anteriorly, the fibrous tunic consists of the cornea, a clear layer of dense regular fibrous connective tissue. 2  Extending from the cornea to cover the sides and posterior of the eye is the sclera.

- The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disk is located towards the nose. The macula or macula lutea (from Latin macula, spot + lutea, yellow) is an oval-shaped pigmented area near the center of the retina of the human eye. It has a diameter of around 5.5 mm (0.22 in). The macula is subdivided into the umbo, foveola, foveal avascular zone (FAZ), fovea, parafovea, and perifovea areas.

- 1 Light focused by the cornea and crystalline lens (and limited by the iris and pupil) then reaches the retina  the light-sensitive inner lining of the back of the eye. 2  The retina acts like an electronic image sensor of a digital camera, converting optical images into electronic signals.ther parts of the human eye play a supporting role in the main activity of sight: 1  Some carry fluids (such as tears and blood) to lubricate or nourish the eye. 2  Others are muscles that allow the eye to move. 3  Some parts protect the eye from injury (such as the lids and the epithelium of the cornea).

Fovea centralis The fovea centralis (the term fovea comes from the Latin, meaning pit or pitfall) is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for activities where visual detail is of primary importance, such as reading and driving.he parafovea extends to a radius of 1.25 mm from the central fovea, and the perifovea is found at a 2.75 mm radius from the fovea centralis.

- Only in the fovea are the layers of the retina spread aside to let light fall directly on the cones, the cells that give the sharpest image. Also called the central fovea or fovea centralis. The word fovea is the Latin word for small pit.. The fovea is literally a small depression (in the retina).

Eye Anatomy: Parts Of The Eye 1 The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by automatically adjusting the size of the pupil (aperture).  The eye's crystalline lens is located directly behind the pupil and further focuses light.

About the Eye and How It Works The Cornea. The cornea is a transparent dome-shaped tissue that forms the front part of your eye. It functions as a window and allows light to enter your eye. It also begins the process of focusing light rays that allow you to see words and images clearly. The cornea provides 65-75% of your eye's focusing power.

Cornea The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye). The cornea's main function is to refract, or bend, light. The cornea is responsible for focusing most of the light that enters the eye. The cornea is composed of proteins and cells. It does not contain blood vessels, unlike most of the tissues in the human body.

Eye Anatomy: How Do Our Eyes Work? The center of the retina contains the macula. The macula is a highly sensitive part of the retina that is responsible for our detail vision. The center of the macula, which has a major role in detail perception, is called the fovea.When there is damage to the macula, we are unable to see fine details.he Lens. The lens is a clear structure behind the pupil that does just what a regular lens does. The main purpose of the lens is to focus light by changing shape. The ciliary body is a muscle group attached to the lens that help the lens change its shape to better focus light on the retina.
