Zhou Dynasty (c. 1050-256 BCE). 1  The Zhou dynasty (c.1050-256 BCE) conquers and succeeds the Shang; later generations seek to reclaim and preserve the idealized peace of the early Zhou (or Western Zhou) period.
Learning Center > Health Library > Optic Nerve. The optic nerve is located in the back of the eye. This structure is responsible for transferring the images we see from the retina to the brain. The front surface of the optic nerve, which is visible on the retina, is called the optic disc.
The Optic Nerve is the second of the Twelve Cranial Nerves. It consists of both afferent and efferent visual sensory fibers. The word afferent means toward the centre, as in from a peripheral area of a limb to the central nervous system. Henceforth the optic fibers travel within the optic nerve, known as the optic tract. 2  At the optic chiasm, half of the fibers continue into the optic nerve proper, while the other half cross over and continue on the contralateral side and vice versa.
