Physiology of the Eye, Fourth Edition reviews major advances in the physiology of the eye, including improvements in photochemical and electrophysiological techniques. In particular, the successful application of modern microelectrode techniques to the recording of activity at all stages in the visual pathway is considered.

Human Eye: Anatomy, parts and structure

The human eye is a paired sense organ that reacts to light and allows vision. Rod and cone cells in the retina are photoreceptive cells which are able to detect visible light and convey this information to the brain. Eyes signal information which is used by the brain to elicit the perception of color, shape, depth, movement, and other features. The eye is part of the sensory nervous system. Similar to the eyes of other mammals , the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment of the size of the pupil, regulation and suppression of the hormone melatonin , and entrainment of the circadian rhythm.

Lecture 1 Dr. Wajida Saad Bun yan Anatomy a nd Physiology of t he Eyeball The eye consists of three layers: the fibrous, vascular, and nerve layers, and additionally, the ocular media. Fibrous Layer : The fibrous layer is the outer layer of the eye, co nsisting of two parts, the cornea and the sclera. The cornea is an a vascular, transparent organ, the clear, dome -like structure in front of the visible iris. It is a convex structure with a horizontal diameter of 12 millimeters and a vertical measuremen t of 10 - 11 millimeters.

Human Eye: Anatomy, parts and structure The eye is the photo-receptor organ. Size and shape: Human eye is spherical about 2. Location: it is situated on an orbit of skull and is supplied by optic nerve. There are 6 sets of muscles attached to outer surface of eye ball which helps to rotate it in different direction. Four sets of these muscles are straight muscles; superior, inferior, medial and lateral rectal muscle and two sets are oblique muscles; superior and inferior oblique muscles. Structurally two eyes are separated but some of their activities are coordinated so that they functions as a pair.

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. The majority of the rods are located in the peripheral, or outer area, of the retina.


The eye is embryologically an extension of the central nervous system. It shares many common anatomical and physiological proper- ties with the brain.

Он кивнул: - Чтобы предупредить. - Предупредить. Он же вас ненавидит. - Он позвонил и предупредил, что заканчивает работу над алгоритмом, создающим абсолютно стойкие шифры. Я ему не поверил.

 - Он повернулся к бригаде своих помощников.  - Кто знает, какая разница между этими элементами. На лицах тех застыло недоумение.

Беккер спустился вниз, постоял, глядя на самолет, потом опустил глаза на пачку денег в руке. Постояв еще некоторое время в нерешительности, он сунул конверт во внутренний карман пиджака и зашагал по летному полю. Странное начало. Он постарался выкинуть этот эпизод из головы. Если повезет, он успеет вернуться и все же съездить с Сьюзан в их любимый Стоун-Мэнор.

Она была его иллюзией, его живой фантазией. Он мечтал о ней по ночам, плакал о ней во сне. Он ничего не мог с собой поделать. Она была блистательна и прекрасна, равной ей он не мог себе даже представить. Его жена долго терпела, но, увидев Сьюзан, потеряла последнюю надежду.
