Plexus periarterialis is a scientific term that refers to the network of nerves and blood vessels that surround an artery. This complex system plays a crucial role in maintaining blood flow and regulating blood pressure. While the term may be unfamiliar to many, there are several synonyms that can be used to describe this structure. These include arterial plexus, periarterial nerves, and neurovascular bundle. Each term highlights a slightly different aspect of the complex network, ranging from the anatomical location of the nerves and blood vessels to their overall function. Regardless of the terminology used, the plexus periarterialis remains a critical component of the cardiovascular system.
