| Front | Cardiac reflexes |

| Back | Structure: chemoreceptors and baroreceptors are located in the walls of the great vessels, and are connected to viscerosensory reflex neurons (cell bodies in sensory ganglia of vagus nerve). Function: detect changes in blood composition and pressure and alter the brain. 1. Pressure or composition of blood changes and viscerosensory reflex neurons are activated. 2. Viscerosensory reflex axons travel with parasympathetic neurons back to CNS, which can produce effects to counteract changes in blood. |
