Explain the ascending pathway of how the information about touch sensation travels from the right arm up to the brain where he is aware that he has been touched. (Use complete sentences.) Use these key words in this order: sensory neuron, radial nerve in brachial plexus, spinal nerve, dorsal root ganglion, dorsal root, dorsal horn in cervical spinal cord, ascending tract, decussate, somatosensory cortex in postcentral gyrus, parietal lobe, Mr. Dexter thinks “Someone touched my arm.”)
Drag the function of the somatic sensory pathway to its proper location on the spinal cord.
Drag the appropriate labels to their respective targets.
