The brain and spinal cord both are involved in this reaction but my support is for both.
- When we are pricked by a cactus, the sensory neurons are activated immediately.
- They take the message to the brain or spinal cord.
- The massage given by the brain or spinal cord is brought back by the motor neuron.
- The motor neuron carries the message to the hand muscles. We immediately pull our hands away from the cactus.
