Anatomy And Function Of The Eye

The eye has many parts that must work together to produce clear vision. The optic nerve transmits these signals to the brain which forms an image so thereby providing sight.

What Is The Macula

Anatomy of the eye.

Anatomy and function of the eye. Extraocular muscles help move the eye in different directions. Multiple genes inherited from each parent determine a persons eye color. And when there is low light the iris opens up the pupil to let in more light.

Nerve signals that contain visual information are transmitted through the optic nerve to the brain. When there is bright light the iris closes the pupil to let in less light. Lens focuses light rays onto the retina.

Layer of the eye behind the retina contains blood vessels that nourish the retina. Iris the colored part of the eye which helps regulate the amount of light entering the eye. This is a short movie on the eye its anatomy and function.

The surface of the eye and of the inner eyelids is covered by a clear protective membrane called the conjunctiva. The outer layer of the eyeball is a tough white opaque membrane called the sclera the white of the eye. The photoreceptor nerve cells present in the macula and concentrated in the fovea the very center of the macula.

The eye is shaped like a round ball with a slight bulge at the front. The macula is a small extra sensitive area in the retina that gives you central vision. The eye has many parts which work together to accomplish vision and to keep the structures required for vision safe from infection and injury.

It collects light from the visible world around us and converts it into nerve impulses. Part of the eye above the lens that produces the aqueous humor. The eye has three main layers.

Anatomy of the eye. The eye is surrounded by the orbital bones and is cushioned by pads of fat within the orbital socket. The pupil or black dot at the centre of the eye is a hole through which light can enter the eye.

Light enters through the cornea past the iris through the pupil refracted by the lens and onto the retina of the eye. A note to all media companies or individuals who wish to use this animation. Behind the eye your optic nerve carries these impulses to the brain.

Eye color is created by the amount and type of pigment in your iris. The nerve at the back of the eye that transports electric signals to the brain. The sclera or white part of the eye protects the eyeball.

The iris or coloured part of the eye surrounds the pupil. The eye is a sensory organ. Image starts right side up from outside the eye and is flipped upside down on the retina.

These layers lie flat against each other and form the eyeball. Enable people to see fine detail and color. The anatomy of the eye.
