Predict what might happen if a disease caused the axons of the first-order somatosensory neurons that transmit proprioceptive stimuli to lose their myelin sheaths. Predict what might happen if a disease caused the axons of the first-order somatosensory neurons that transmit proprioceptive stimuli to lose their myelin sheaths. Muscular contractions would be stimulated at slower pace. Increased pain sensation would occur. Lack of coordination during walking would be present. Information would be relayed quicker to the second order neurons in the spinal cord.
