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.
Gray and white matter. The brain of humans consists of gray matter and white matter. The gray matter contains the nerve cells. White matter - myelin. The white matter of the brain is composed of nerve fibers and myelin. The nerve fibers form the connections between the nerve cells. Myelin is a fatty sheath wrapped around nerve fibers. The myelin sheath has two functions: insulation and acceleration of impulse conduction.
