automatic control systems

• What are the three components of automatic control systems?

  Receptor, coordination centres, effectors
• What is the role of receptors in automatic control systems?

  They detect a change in the environment
• How do coordination centres function in automatic control systems?

  They interpret changes and decide actions
• What do effectors do in automatic control systems?

  They carry out the necessary changes
• How does the nervous system communicate changes?

  It sends electrical impulses through nerves
• What is the response speed of the nervous system?

  It responds quickly
• How does the endocrine system communicate changes?

  It relies on hormones released into the bloodstream
• What is the speed and duration of the endocrine system's response?

  Slower, longer lasting, and more generalized
• What mechanism do both systems use to maintain balance?

  Negative feedback
• What happens when a level gets too high in negative feedback?

  Negative feedback decreases the level
• What occurs if a level decreases too much in negative feedback?

  Negative feedback increases the level again
• What is the sequence of events in an automatic control system?

  Receptors detect change, nervous system sends impulses
• What do coordination centres do after receiving impulses?

  They send another set of signals to effectors
