legal blindness - vision that is 20/200 or worse in both eyes (20/200 vision is the ability to see at 20 feet what a normal eye can see at 200 feet) blindness, cecity, sightlessness - the state of being blind or lacking sight.
In this review, we outlined those postural reflexes related to pathways and structures involving the cervical spine, the eyes, and the inner ear. How these structures and pathways obtain somatosensory input, interact with each other, and modulate postural changes and corrections has been described here.
Pain travels through âredundantâ pathways, ensuring to inform the subject to Get out of this situation immediately.. 7.1 Pain Pathways. The ascending pathways that mediate pain consist of three different tracts: the neospinothalamic tract, the paleospinothalamic tract and the archispinothalamic tract.The first-order neurons are located in the dorsal root ganglion (DRG) for all three pathways.ain travels through âredundantâ pathways, ensuring to inform the subject to Get out of this situation immediately.. 7.1 Pain Pathways.
