Which is involved in the pathway that causes an immediate increase in ventilation rate at the beginning of exercise?
◦ Mechanoreceptors and proprioceptors in muscles send information to the motor cortex of the brain and widespread vasoconstriction causes increase in blood pressure.
◦ Output from the limbic system and cardiovascular control center triggers parasympathetic discharge and widespread vasoconstriction causes increase in blood pressure.
