Neural control

• 1)The receptors detect an increase:

  -proprioreceptors detect muscle movement

  -chemoreceptors detect change in lactic acid and CO2

  -Baroreceptors detect a change in blood pressure
• 2)the CCC is the cardiac control centre

  -the medulla oblongata
• 3)An increase in sympathetic NS ——> accelerators nerve
• 4)A decrease stimulation of parasympathetic NS ——> Vagus nerve
• 5) SA node is stimulated in the heart which increases the heart rate
