UNIT 3 The Interaction Function Natural Science 2. Secondary Education • THE INTERACTION FUNCTION PROCESSES 1: Light makes a bird visible to the cat, which also detects sound vibrations (chirping). 2: The visual and acoustic signals reach the cat’s sensory organs. 3: The sensory organs transmit the information to the central nervous system. • First, the receptor organs of living beings capture information and send signals to the processing centers. The central nervous system processes this information and generates an appropriate response (there is a bird, and I will try to catch it). • Then, the coordination centers process the signals from the receptors and prepare a response. The cat’s muscles, part of its locomotor system, receive the command to respond and execute movements to attempt to catch the prey. • Finally, the effectors receive signals from the coordination centers and carry out the response. • RECEPTOR • RESPONSE • EFFECTOR • COORDINATION CENTER • STIMULUS The interaction function is perceived through the receptors, which send messages to the nervous system.
