D
The sensory assessment is divided into three sections. First, the exteroceptive sensations (superficial sensations that originate in the sensory receptors in the skin and mucous membranes) are tested. These are the sensations of light touch, superficial pain, and temperature. Next, the proprioceptive sensations (deep sensations, with sensory receptors in the muscles, joints, tendons, and ligaments) are assessed. Proprioception is tested with the modalities of motion and position, and vibration sense. Finally, the cortical sensations (those that require cerebral integrative and discriminative abilities) are assessed. Stereognosis, graphesthesia, two-point discrimination, and extinction are tested.
