The upper oblique muscles of the back of the train coming. He travels through a small pulley (trochlea) in orbit around the nose and is at the top of the eye then. The upper inclined inner eye rotates about the longitudinal axis of the eye (front to back). The superior oblique eye also moves down.
The lower oblique eye muscles out at the front of the train near the nose. Then outwardly and rearwardly moving in orbit before the mounting on the floor of the eyeball. Eye is turned (to the rear from the front) to the outside along the longitudinal axis of the eye. The lower oblique eye also moves upward.
Conjunctiva:
The conjunctiva is a transparent mucous membrane, which comprises the inner surface of the eyelid and the eye surface. When it becomes inflamed or infected red or pink. This is called conjunctivitis or "Red Eye".
Lacrimal gland:
The lacrimal gland produces tears to lubricate the eye. It is under the side edge of the eyebrows in orbit.
Pins:
Tenon's capsule is a layer of tissue that lies between the eye surface and the conjunctiva.
Dermis:
The sclera is the white outer wall of the eye. Almost the entire surface of the eyeball covered. There is a strong layer of collagen fibers. The tendons of the six eye muscles attach sclera.Cornea:
The cornea assumes the middle in front of the outer wall of the eye. It consists of collagen fibers in a special arrangement made for the cornea is clear. It searches through the cornea, the iris and pupil to see. Cornea curves light entering the eye may be focused on the retina. The cornea is the part of the eye to which places the contact lenses.
Internal (intraocular) Anatomy
Anterior Chamber:
The anterior chamber is a liquid (aqueous humor) fills the space within the eye. The cornea from the anterior chamber and iris and pupil behind him.
Iris / students:
The iris is the colored part of the eye. It is fit with a hole in the middle (the pupil) hard drive. The muscles in the iris cause the pupil in bright light to constrict and dilate in low light conditions. The change in the pupil size regulates the amount of light that the back (rear) of the eye.
Lens:
The lens of the eye, is just behind the pupil. The curved lens light in the eye to help focus on the retina. It changes its shape to help focus the views of objects to see clearly up close. The lens is suspended from the wall of the eye for many small fibers (zonules) at its capsule adhere.
Ciliary body:
The ciliary body is attached to the outer edge of the iris in the vicinity of the eye wall. The ciliary body produces fluid (aqueous humor) that fills the eye and nourishes its structures. It also helps to change the shape of the lens when focus occurs.
Viteous:
The vitreous body is disposed between the lens and the retina is filled 4/5 of the interior of the rear part of the eye. A gelatinous substance, known as the vitreous humor fills the cavity. This plays an important role in the diet of the internal structures of the eye. Light to be projected into the eye through the pupil and through the vitreous to the retina.
Retina:
The retina is a thin, transparent structure covering the internal wall of the eye. The eye works like a camera, and the retina is like the film in the camera. It's where the images first before they passed through the optic nerve to the brain projected. It is a very complex structure with 10 layers of specialized cells, including photoreceptor cells (rods and cones).
Photoreceptors:
The photoreceptors are highly specialized cells of the retina receive light pulses and change in chemical energy, which can be transmitted by neurons in the brain. The two types of photoreceptors rods and cones. Rods true black and white night vision to serve especially. The cones are responsible for color vision and central vision.
Macula:
The macula is a small area of the retina specialist who has a very high sensitivity and responsible for central vision.
Retinal pigment epithelium (RPE):
The retinal pigment epithelium is a layer of cells deep in the retina. This cell layer helps the function of the photoreceptor cells of the retina by the processing products of vitamin A, the used turning on photoreceptor segments, the light absorption and the transport of nutrients in and out of the photoreceptor cells.
Choroid:
The choroid is a layer of tissue that lies between the retina and sclera. The choroid has a rich supply of blood vessels that nourish the retina.
Uveal tract:
The uvea is a pigmented component of the eye that 1) the iris, 2) the ciliary body, and 3) include the choroid.
Optic nerve:
The optic nerve connects each eye to the brain. It is a structure which transmits image seen by the eye to the brain, so that it can be processed. The end of the optic nerve in a structure called the optic chiasm. In an adult, the optic nerve is approximately the diameter of a pencil. There are over 1 million of individual nerve cells in the optic nerve.
Chiasm:
The optic chiasm is the place in the brain where both optic nerves. Individual nerve fibers in every nerve chiasm are arranged. The classification is carried out such that the right side of the brain controls the view of the objects in the left area and the left brain controls the view of the objects in the right area [see Figure 3].
Visual cortex:
This is an area of the brain in the occipital lobe behind the retina neurons ultimately provide visual information. The visual cortex helps you process information about the image such as color, composition and relationship to other objects in space. This information is then sent to other parts of the brain that serve a higher visual functions.
