Nerve05/disorders of the spinal cord and optic pathway/ascending pathway of temperature and pain sensation

In the ascending pathway for sensation of temperature and pain, the first sensory fiber, after entering the spinal cord from the posterior root, immediately synapses with the cell body of the secondary sensory neuron. The fiber of the sendary neuron crosses the righ-left midline immediately at the spinal nerve level, and ascends the spinal cord on the contralateral side. This pathway is called the spinothalamic tract.
