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.
a reflex whose center is located in the spinal cord. There are four types of spinal reflexes: somatic (motor), autonomic, segmental, and intersegmental.egmental spinal reflexes occur within a single segment of the spinal cord, and intersegmental spinal reflexes enter and emerge from different spinal segments. Depending on the structure of the reflex arcs, spinal reflexes may be monosynaptic or polysynaptic.
