The plan, the intended victim, the motivation, and other aspects of the threat are masked or equivocal:  1 If I wanted to, I could kill everyone at this school!. While violence is implied, the threat is phrased tentatively.  2 If I wanted toâand suggests that a violent act COULD occur, not that it WILL occur.
The optic nerve is composed of retinal ganglion cell axons and glial cells. Each human optic nerve contains between 770,000 and 1.7 million nerve fibers, which are axons of the retinal ganglion cells of one retina.In the fovea, which has high acuity, these ganglion cells connect to as few as 5 photoreceptor cells; in other areas of retina, they connect to many thousand photoreceptors.ach human optic nerve contains between 770,000 and 1.7 million nerve fibers, which are axons of the retinal ganglion cells of one retina.
The information from the eye is carried by the axons of the retinal ganglion cells (the 3Â° visual afferent) to the midbrain and diencephalon. This chapter will provide more information about visual pathway organization and the visual processing that occurs within the brain.t the optic disc, the 3Â° visual afferents exit the eye and form the optic nerve. The fibers of the optic nerve that originate from ganglion cells in the nasal half of the retina (i.e., the nasal hemiretina) decussate in the optic chiasm to the opposite optic tract (Figure 15.1).
