Questions and Answers

What is the site of decussation for the anterolateral tract?

  • In the thalamus
  • Within the same spinal cord segment where the peripheral afferent neuron enters the spinal cord
  • In the brainstem
  • Within 1-2 spinal cord segments above and below the level where the peripheral afferent neuron enters the spinal cord (correct)
  • What type of fibers do some second order neurons carry in the ALS tract?

  • Slow C pain fibers (correct)
  • Fast A-delta pain fibers
  • Proprioceptive fibers
  • Motor fibers
  • Which of the following is responsible for crude touch and pressure in the ALS tract?

  • The lateral spinothalamic tract (correct)
  • The corticospinal tract
  • The spinocerebellar tract
  • The dorsal column pathway
  • Study Notes

    • The anterolateral pathways refer to the spinothalamic pathway.
    • Second order neurons cross to the opposite anterolateral white column and turn upward toward the thalamus through anterior and lateral spinothalamic tracts.
    • Some second order neurons carry signals from slow C pain fibers and give collateral fibers to reticular formation, periaqueductal gray area, and hypothalamus.
    • The site of decussation for the anterolateral tract is within 1-2 spinal cord segments above and below the level where the peripheral afferent neuron enters the spinal cord.
    • Any unilateral damage to the ALS tract will result in a contralateral loss of sensation.
    • The ALS tract is responsible for crude touch and pressure.
    • The thalamus is involved in the ALS tract.
    • There are three types of neurons involved in the ALS tract: 1st order, 2nd order, and 3rd order.
    • The lateral spinothalamic tract is involved in the ALS tract.
    • The substantia gelatinosa is involved in the ALS tract.
