4 Multiple Choice 1 point Which of the following statements CORRECTLY describes the function of a component of a reflex arc? Sensory neurons gather information from effectors Motor neurons conduct impulses from interneurons to effectors Sensory receptors receive stimuli from interneurons Effectors act as integration centres Clear my selection

Answer 1

The correct answer is: **Motor neurons conduct impulses from interneurons to effectors.**Here's why:* **Sensory neurons:** These neurons gather information from sensory receptors (not effectors) and transmit it towards the central nervous system (CNS).* **Motor neurons:** These neurons receive impulses from the CNS (often via interneurons) and transmit them to effectors (muscles or glands) to produce a response.* **Sensory receptors:** These specialized structures detect stimuli from the environment (not interneurons) and initiate nerve impulses in sensory neurons.* **Effectors:** These are muscles or glands that carry out the response to a stimulus. They do not act as integration centers; that role belongs to the CNS (brain and spinal cord).* **Interneurons:** These neurons are found within the CNS and connect sensory and motor neurons. They play a role in integrating and processing information.
