Does the cerebrum control touch?

The cerebral cortex controls the sensory systems, including touch. The main sensory control is housed in the parietal lobe of the cerebral cortex where the brain receives and interprets the sensation of touch and then creates a motor plan based on the information it receives. For example: you're walking in a crowded hallway and you bump elbows with the person walking next to you. The touch receptors in your skin send the impulse up the spinal cord to the sensory cortex. The cortex processes this impulse and perceives that you are too close to that person. The cortex then sends a motor response to the musculoskeletal system to move an inch to the right with the next step to avoid hitting that person.
