Physiology of Acupressure and Acupuncture: Impulse through
Extra-neural pathways
Jayakar J Joseph
Introduction: Acupuncture
Meridian System
Stimulation of specific Acupuncture points along the skin using thin needles
About 400 acupuncture points along 20 pathways:12 primary 8 extraordinary channels
Traditional Chinese Medicine
Application of heat, pressure, low voltage AC current or laser light to these points
Introduction: Acupressure
The energy roller is a small cylinder with protuberances.
The foot roller. The power mat: small pyramid-shaped bumps that you
walk on. The spine roller is a bumpy roller containing magnets
that is rolled up and down the spine
Pressure by rubbing, rolling, or applying pressure on the reflex zones of the body.
Physiology of Impulse Sensing
Sensory receptor initiates sensory transduction by creating graded potentials or action potentials
First-order sensory neuron
When receptor exceeds a level of intensity electrical impulse travels down the Nerve fibre to the central nervous system
Sensory transduction
Conversion of a sensory stimulus from one form to another
Chemical synapse
• creating graded potentials or action potentials in the same cell or in an adjacent one.
Physiology of Impulse transmission
Membrane potentialAction potential
Difference in electrical potential between the interior and the exterior of a cell. Ranges from –40 mV to –80 mV.
Short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory
Created graded potential of Adjacent cell
Graded potential
Where the Acupuncture points intercepts
Acupuncture point
