About :

The video shows the structure of the human eye and visual analyzer. It will be useful both in preparation for the Unified State Exam in biology, and in preparation for classes, tests and Olympiads in biology. The peripheral section of the visual analyzer is the retina. The conduction section of the visual analyzer is the optic nerve. The central section of the visual analyzer is the visual zone of the cerebral cortex (in the occipital lobe of the cerebral cortex). The human eye: eyeball, optic nerve, accessory organs. The eyeball is divided into the eye membranes and the inner core of the eye. The outer shell of the eye is represented by the sclera (white shell) and cornea. The middle shell of the eye: the choroid, iris and ciliary body. The inner shell of the eye is the retina. The inner core of the eye: the vitreous body, the lens, the aqueous humor of the anterior and posterior chambers of the eye. Optical system of the eye: cornea, aqueous humor of the anterior and posterior chambers of the eye, lens, vitreous body. Accessory organs of the eye: eyebrows, eyelids, eyelashes, lacrimal apparatus (includes lacrimal glands), muscles of the eyeball (motor apparatus of the eye), conjunctiva.
