THE INTERACTION FUNCTION PROCESSES

UNIT

3 The interaction function processes

1: Light makes a bird visible to the cat. The bird also emits sound vibrations (chirping).

2: The visual and acoustic signals reach the cat’s sensory organs.

3: The sensory organs send the information they receive to the central nervous system.

• First, the receptor organs of living things capture information and send signals to the processing centres.

The central nervous system processes the information received and produces a suitable response (there is a bird there and I’m going to try to catch it).

• Then, the coordination centres process the signals from the receptors and prepare a response.

The cat’s muscles, part of its locomotor system, receive the order to respond and carry out movements in order to try to catch the prey.

• Finally, the effectors receive the signals from the coordination centres and carry out the response.
