📖 1. Nervous System Functioning

🔑 Key Concepts & Definitions

  • Stimulus: A change in a physico-chemical parameter in the environment detected by a receptor.
  • Receptor: A structure that converts a stimulus into a nerve message.
  • Effector: An organ that produces a response to a stimulus.
  • Centres nerveux (Nerve centers): Collections of nerve cells, including ganglia, brain, and spinal cord, where sensory messages are processed and motor messages originate.

📝 Essential Points

  • The nervous system enables organisms to react to environmental stimuli by transmitting nerve messages.
  • Nerve centers process sensory inputs and generate motor outputs to effectors.
  • Neurons are specialized cells responsible for receiving, generating, propagating, and transmitting nerve messages.
  • The system includes sensory receptors, nerve centers, and effectors working together for coordinated responses.

💡 Key Takeaway

Understanding these fundamental components and their roles reveals how organisms detect and respond to environmental changes effectively.
