Verified step by step guidance
1
Understand the components of a reflex arc: A reflex arc typically consists of five main components: receptor, sensory neuron, interneuron, motor neuron, and effector.
Identify the role of each component: The receptor detects the stimulus, the sensory neuron carries the signal to the central nervous system, the interneuron processes the information, the motor neuron carries the response signal, and the effector performs the action.
Focus on the motor response: The motor response is the action taken by the body in response to the stimulus detected by the receptor.
Determine which component carries out the motor response: The motor neuron is responsible for transmitting the signal from the central nervous system to the effector, which carries out the motor response.
Conclude that the motor neuron is the component responsible for carrying out the motor response in a reflex arc.
