Final answer:
The three fundamental steps in all sensory systems are receiving stimuli, transduction into electrical signals, and delivering information to the brain for a response.
Step-by-step explanation:
The three steps that are basic to all sensory systems include the receiving of stimuli by sensory receptors, transduction of the stimulus into an electrical signal via the peripheral nervous system, and delivering or transmission of this information to the brain for integration and response. The first step, reception, involves the activation of sensory receptors by stimuli such as mechanical stimuli, chemicals, or temperature. The second step, transduction, is where a sensory receptor converts a stimulus into an electrical signal that can be relayed to the central nervous system. The final step, in the cerebral cortex, involves the integration of the sensory perception, which can lead to a specific response.
