spinothalamic tract in a sentence
Examples
- Cordotomy involves cutting into the spinothalamic tracts, which run up the front / side ( anterolateral ) quadrant of the spinal cord, carrying heat and pain signals to the brain.
- There are two main parts : the lateral spinothalamic tract, which transmits pain and temperature, and the anterior ( or ventral ) spinothalamic tract, which transmits crude touch and pressure.
- There are two main parts : the lateral spinothalamic tract, which transmits pain and temperature, and the anterior ( or ventral ) spinothalamic tract, which transmits crude touch and pressure.
- The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it provides ( pain and temperature ) sensory information.
- Unmyelinated nerve fibers for itch and pain both originate in the skin; however, information for them is conveyed centrally in two distinct systems that both use the same nerve bundle and spinothalamic tract.
- Interestingly, temperature and pain perception follow the same neural pathway from the peripheral nervous system to the diencephalon-- the spinothalamic tract .-- Mark Bornfeld DDS 17 : 39, 19 September 2006 ( UTC)
- The loss of sensation on the opposite side of the lesion is because the nerve fibers of the spinothalamic tract ( which carry information about pain and temperature ) crossover once they meet the spinal cord from the peripheries.
- A delta fibers ( A? fibers ) and C fibers carrying pain sensation in the spinothalamic tract contribute to this commissure, as do fibers of the anterior corticospinal tract, which carry motor signals from the primary motor cortex.
- On the contralateral ( opposite side ) of the lesion, there will be a loss of pain and temperature sensation and crude touch 1 or 2 segments below the level of the lesion via the Spinothalamic Tract of the Anterolateral System.
- Sensation of pain and temperature is preserved, because the spinothalamic tract is located more laterally in the brainstem and is also not supplied by the anterior spinal artery ( instead supplied by the posterior inferior cerebellar arteries and the vertebral arteries ).
