The<unk>  is a sensory pathway originating in the spinal cord that transmits information about pain, temperature, itch and crude touch to the thalamus. The pathway decussates at the level of the spinal cord, rather than in the brainstem like the posterior column-medial lemniscus pathway and corticospinal tract.
The cell bodies of neurons that make up the<unk>  are located principally within the dorsal horn of the spinal cord. These neurons receive input from sensory fibers that innervate the skin and internal organs.
