Questions and Answers

What is the primary function of transmission in the nervous system?

  • To regulate reflexive actions in the spinal cord
  • To integrate motor responses to external stimuli
  • To process sensory information in the brain
  • To send impulses from the site of transduction to the brain (correct)
  • What is the first stage of the transmission process?

  • From the brain stem to the thalamus
  • From the site of transduction to the dorsal horn of the spinal cord (correct)
  • From the spinal cord to the brain stem
  • Through connections between the thalamus, cortex, and higher levels of the brain
  • What is the final stage of the transmission process?

  • From the dorsal horn to the spinal cord
  • From the spinal cord to the brain stem
  • From the brain stem to the spinal cord
  • Through connections between the thalamus, cortex, and higher levels of the brain (correct)
  • How many stages are involved in the transmission process?

    Study Notes

    Transmission of Impulses

    • Impulses are sent to the dorsal horn of the spinal cord through transmission
    • Transmission occurs in 3 stages

    Stage 1: Signal Propagation

    • Signals are transmitted from the site of transduction to the dorsal horn of the spinal cord

    Stage 2: Signal Relaying

    • Signals are transmitted from the spinal cord to the brain stem

    Stage 3: Higher-Level Processing

    • Signals are transmitted through connections between the thalamus, cortex, and higher levels of the brain
