Question

Simple two neuron reflex involves

• A. Sensory neuron
• B. Spinal cord
• C. Effector neuron
• D. All of the above

Answer 1

Answer: (D)

All of the above

Simple two neuron reflex arc consists of a sensory neuron, center and efferent (effector) neuron. The sensory neurons transmit the sensory information from sensory receptors to the spinal cord (sensory pathway). Spinal cord integrates the incoming information and signal is relayed to effector neurons. The effector neuron transmits the signal from the spinal cord to the effector organs (muscles and glands etc). Thus, the correct answer is option D.
