Questions & Step-by-Step Solutions
In a simple reflex arc, which component detects the stimulus?
Step 1: Understand what a reflex arc is. It is a pathway that the body uses to respond quickly to a stimulus.
Step 2: Identify the components of a reflex arc. These include the sensory receptor, sensory neuron, central nervous system, motor neuron, and effector.
Step 3: Focus on the sensory receptor. This is the part that detects the stimulus, like heat, light, or pressure.
Step 4: When the sensory receptor detects a stimulus, it sends signals to the central nervous system.
Step 5: The central nervous system processes the information and sends a response back through the motor neuron to the effector.
