Pathway of a Reflex Arc

  • Reflexes - involuntary & rapid actions
  • Control - your spinal cord usually controls reflexes

Reflex Arc -

  • Most reflexes don't have to travel up to your brain to be processed, which is why they take place so quickly.
  • A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited.
  • They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron.
  • As a result, one of your muscles or glands (effector) is stimulated.
