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.
SEARCH. A receptor, a sensory neuron, a motor neuron, The motor neuronâs innervation of the peripheral nervous system, and at least one association neuron from the central nervous system are the ingredients to a conduction passageway of the reflex arc.ensory and motor neurons are part of this reflex, as are association neurons. Pain is the most obvious stimuli that initiates the flexor reflex, as painful stimuli sets the whole reflex into action. The receptor responds and sends the information via sensory neurons.
