Created Date: 6/27/2012 11:57:40 A The structure of the eye is an important topic to understand as it one of the important sensory organs in the human body. It is mainly responsible for vision, differentiation of colour (the human eye can differentiate approximately 10 - 12 million colours) and maintaining the biological clock of the human body

Fig. 1.4: Diagram showing Foveamuscles. Each eye moves in all the directions. The eyes also have a rotational movement. Horizontal eye movements are controlled by the medial and lateral rectus muscles, while superior rectus and interior rectus muscles perform superior and inferior movement of the eyes. A machine is used by opthamologists to record muscle balances and movements of eyes it is called synaptophore (see Fig. 1.5) Eye Anatomy: Parts of the Eye Outside the Eyeball. The eye sits in a protective bony socket called the orbit. Six extraocular muscles in the orbit are attached to the eye. These muscles move the eye up and down, side to side, and rotate the eye. The extraocular muscles are attached to the white part of the eye called the sclera. This is a. Many eye diagrams are constructed on test equipment that uses test patterns that repeat, such as PRBS patterns generated by a BERT (Bit Error Ratio Tester). Such equipment can commonly generate a variety of trigger signals: A clock trigger at the same rate as, and synchronous with the data signa On a diagram of the eye, we can see all of the relevant structures together on one image.

Simple Anatomy of the Retina by Helga Kolb. Helga Kolb. 1. Overview. When an ophthalmologist uses an ophthalmoscope to look into your eye he sees the following view of the retina (Fig. 1). In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x 1.5 mm across. From the center of the optic nerve radiates. An eye diagram is used in electrical engineering to get a good idea of signal quality in the digital domain. To generate a waveform analogous to an eye diagram, we can apply infinite persistence to various analog signals a well as to quasi-digital signals such as square wave and pulse as synthesized by an arbitrary frequency generator (AFG) The Eye - Science Quiz: Our eyes are highly specialized organs that take in the light reflected off our surroundings and transform it into electrical impulses to send to the brain. The anatomy of the eye is fascinating, and this quiz game will help you memorize the 12 parts of the eye with ease. Light enters our eyes through the pupil, then passes through a lens and the fluid-filled vitreous.
