Study Notes

Steps of Neural Reflex

  • Step 1: Arrival of Stimulus

    • Initiates reflex action by detecting a stimulus at the receptor level.
    • Involves physical or chemical changes in the environment that trigger the response.
  • Step 2: Activation of Sensory Neurons

    • Sensory neurons are activated leading to graded depolarization.
    • This signal transmits sensory information towards the central nervous system.
  • Step 3: Information Processing by Postsynaptic Cell

    • The postsynaptic cell processes incoming signals.
    • This processing results from neurotransmitter release, influencing the postsynaptic neuron's excitability.
  • Step 4: Activation of Motor Neuron

    • Motor neurons are activated and generate an action potential.
    • This action potential carries the response signal away from the central nervous system to effectors.
  • Step 5: Response of Peripheral Effector

    • The final step involves the action of peripheral effectors such as muscles or glands.
    • This results in a physiological response to the initial stimulus, completing the reflex arc.
