According to the diagram "What steps link sensory stimuli to animal activity?", what is the correct sequence of information flow in the nervous system from sensory input to motor output?

  • A: Sensory receptors -> Central nervous system -> Motor output
  • B: Motor output -> Central nervous system -> Sensory receptors
  • C: Central nervous system -> Sensory receptors -> Motor output
  • D: Sensory receptors -> Motor output -> Central nervous system

Explanation

The diagram clearly illustrates that sensory receptors receive stimuli and transmit signals to the central nervous system processing center , which then decodes and processes these signals, leading to a motor output via muscles or glands. This represents the basic flow of information in a reflex arc or sensory-motor pathway.
