spinal cord Termination:

• The fibers from both the tracts terminate in the central posterolateral nucleus of thalamus.
• Cells of this nucleus forms the third order neurons.
• Fibers from this nucleus carry the impulses to sensory cortex of cerebral cortex.

spinal cord Function:

1. Anterior spinothalamic tract.

• It conveys.
  • Crude touch
  • Crude pressure
  • Tactile localization.

2. Lateral spinothalamic tract.

• It carries
  • Pain sensation
  • Temperature sensation.
