CS 330 Graphics Cameras and Color Biology Diagrams The Human Visual System. The visual system includes both the eyes and the brain. Light enters your eye where it hits the retina, which triggers light receptors to send electrical signals through your optic nerve, which travel to the back of your brain where the first stages of visual perception take place. visual system" /> Source:https Aqueous humor is made by the ciliary body and flows along the posterior surface of the iris in the narrow posterior chamber. It then flows through the pupil and fills the anterior chamber. The scleral venous sinus (the old name is much more fun to say: the "canal of Schlemm") is a drainage system for the aqueous humor. Humans are "Visual animals" and a relatively large proportion of human brain tissue is devoted to vision. The visual system includes the eye and retina, the optic nerves, and the visual pathways within the brain, where multiple visual centers process information about different aspects (shape and form, color, motion) of visual stimuli. + + +
Nervous System The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Respiratory System The respiratory system provides oxygen to the body's cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate.

The retina is the beginning of the nervous system's involvement with the visual system. It consists of five layers of neurons (described below). The pathway of information moves from the back of the eye towards the front, before exiting the back of the eye in an area called the optic disk. Visual information is passed directly through three system, in combination with skilled examination, allows precise localization of neuropathological processes. Moreover, these principles guide effective diagnosis and management of neuro-ophthalmic disorders. The visual pathways perform the function of receiv-ing, relaying, and ultimately processing visual informa-tion. Learning Objectives. By the end of this section, you should be able to. 6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths.; 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image.; In this section, we will meet the range of the
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment. The visual system is associated with the eye and functionally divided into the optical system (including The tract splits into two. The larger visual fibers head to the lateral geniculate body. The smaller fibers for the light reflex pass between the lateral and medial geniculate bodies to the midbrain. Visual fibers. The lateral geniculate body of the posterior part of the thalamus contains the third-order neurons of the visual system. Of its 6
