  2. Gate Theory of Pain Inhibition
  3. Opioid Peptides and Analgesia
  4. Supraspinal Descending Analgesia
  5. Peripheral Gating and Treatment

1. Central Pain Control Principles

Key Concepts & Definitions

  • Pain control system : inhibits pain transmission and perception in central sensory pathways through ascending and descending impulses

Essential Points

  • Pain responses vary between individuals, injuries may be ignored during stressful conditions such as accidents or battles, and irritating the skin over a diseased viscus can relieve pain.

Memory Hook

Ascending pathways transmit pain, whereas descending pathways inhibit it.

2. Gate Theory of Pain Inhibition

Key Concepts & Definitions

  • Gate theory : states that dorsal horn cells, especially substantia gelatinosa region cells, act as a gate controlling pain transmission

Essential Points

  • Substance P released from C pain fibers opens the dorsal-horn gate, whereas preventing substance P release produces presynaptic inhibition and decreases or blocks pain sensation.
