Catecholamines are neurotransmitters that are produced in the adrenal glands and are released during a stress response. Some typical effects are increased heart rate, increased blood glucose levels and elevated blood pressure. Examples include dopamine, norepinephrine, and epinephrine. Reserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Which of the following rows correctly identifies the effect of reserpine in the synapse and the division of the nervous system it affects? Select one: a. Effect in the Synapse Division of the Nervous System Keeps catecholamines longer Sympathetic nervous system in the synapse b. Effect in the Synapse Division of the Nervous System Inhibits release of catecholamines from the presynaptic neuron Sympathetic nervous system C. Effect in the Synapse Division of the Nervous System Inhibits release of catecholamines from presynaptic neuron Parasympathetic nervous system d. Effect in the Synapse Division of the Nervous System Keeps catecholamines longer in the synapse Parasympathetic nervous system
