Neural control

• Neural control - Receptors


  • Chemoreceptors
  • Proprioceptors
  • Baroreceptors
• Neural control - During exercise


  1. Receptors detect changes and inform the cardiac control centre

  2. Sympathetic nervous system stimulated, impulses sent down accelerator nerve to increase heart rate
• Neural control - During recovery


  1. Receptors detect changes and inform the cardiac control centre

  2. Parasympathetic nervous system stimulated, impulses sent down vagus nerve to decrease heart rate
• Chemoreceptors


  • Detect chemical changes
  • Located in muscles, aorta + carotid arteries
• Proprioceptors


  • Detect changes in movement
  • Located in muscles, tendons + joints
• Baroreceptors


  • Detect changes to blood pressure
  • Located in blood vessel walls
