| The sensory（afferent）action potentials ascend through 3 neurons from the receptors to the cerebral cortex. |
The first sensory nerve has the cell body in the posterior root ganglion.
The second sensory nerve fibers cross the right-left midline and reaches the contralateral brain.
The second sensory nerve fibers form a synapse with the third sensory nerve at the thalamus.
The third sensory nerve fibers passes through the internal capsule and reaches the postcentral gyrus in the parietal lobe of the cerebral cortex.
