When the hand is pricked with a needle, the events that occur are
(A)Skin receptors receives the stimulate → Formation of sensory impulse → A synapse is formed → Association neuron receives sensory impulse and interprets it → Generation of motor impulse → Skeletal muscles receive the impulse and hand is with drawnCorrect
(B)Formation of sensory impulse → Skin receptors receives the stimulate → A synapse is formed → Association neuron receives sensory impulse and interprets it → Generation of motor impulse → Skeletal muscles receive the impulse and hand is with drawn
(C)Skeletal muscles receive the impulse → A synapse is formed → Association neuron receives sensory impulse and interprets it → Generation of motor impulse → Hand is with drawn
(D)Association neuron receives sensory impulse → A synapse is formed → Generation of motor impulse → Formation of sensory impulse → Skeletal muscles receive the impulse and hand is with drawn
Answer: (A)
Solution
The reflex sequence is stimulus reception by receptors, sensory impulse, synapse, interpretation by the association neuron, motor impulse and muscle response; in
