i. Medullary cardiovascular centres. Integrating center

Explanation:  

The efferent parasympathetic pathway is considered to be part of the autonomic nervous system. The efferent parasympathetic control is produced by nerve signals that are transported from the central nervous system to their corresponding targets.  

Targets are those tissues where nerve impulses are directed. These targets include the vascular system (i.e., arterioles, ventricles, veins, etc).  

Receptors are specialized cells capable of detecting a stimulus and promote a response (i.e., an electrical impulse).

The integrating center of the nervous system is represented by the central nervous system (CNS). The CNS is composed by the brain and the spinal cord, it senses the stimulus and produces the corresponding nerve impulse (i.e., response).
