The structures and functions of the eyes are complex. Each eye constantly adjusts the amount of light it lets in, focuses on objects near and far, and produces continuous images that are instantly transmitted to the brain. The orbit is the bony cavity that contains the eyeball, muscles, nerves, and blood vessels, as well as the structures that produce and drain tears. Each orbit is a pear-shaped structure that is formed by several bones. The outer covering of the eyeball consists of a relatively tough, white layer called the sclera or white of the eye. Near the front of the eye, in the area protected by the eyelids, the sclera is covered by a thin, transparent membrane conjunctiva , which runs to the edge of the cornea.

Special cells called cones and rods are located in the retina. These cells are known as photoreceptors and help absorb light. The majority of the cones are located in the macula, or central area, of the retina. Cone cells help us see colour and detail. Similarly, the macula allows us to read and clearly recognize people's facial details, such as eye colour and whether they have freckles.

Both modes require fibroblast growth factor 2 FGF2. So I'm just drawing that in. Move your left hand to unblock your left eye and the gap re-appears. Melanin, the pigment present in the RPE, reduces the scatter of light to the photoreceptors, shielding, them from excessive light exposure Marmor and, Wolfensberger, This article uses the mammalian eye as a primary model and follows the path that light takes on its journey through the functional eye, detailing the essential components of one of the smallest, yet most complex organs in the body.

Вчера он чуть не умер, а сегодня жив, здоров и полон сил. Сьюзан положила голову ему на грудь и слушала, как стучит его сердце. А ведь еще вчера она думала, что потеряла его навсегда. - Дэвид, - вздохнула она, заметив на тумбочке его записку.

Убийца улыбнулся и начал поднимать пистолет. Заслонка. Беккер повернул рычажок под топливным баком и снова нажал на стартер.
