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.
Each neuron is made up of a cell body and an axon (the extension of the cell body that carries messages). Most of the axons in the central nervous system are wrapped in myelin, a substance rich in lipids (fatty substances) and proteins.NS myelin is produced by special cells called oligodendrocytes. PNS myelin is produced by Schwann cells. The two types of myelin are chemically different, but they both perform the same function â to promote efficient transmission of a nerve impulse along the axon.
