The term "periportal commissura" refers to a structure in the liver that connects adjacent portal triads. The IPA phonetic transcription for this term is /pɛrɪˈpɔrtəl kəˈmɪʃərə/, which can help to clarify the spelling of the word. The "peri-" prefix means "around" or "surrounding," while "portal" refers to the hepatic portal vein. "Commissura" is derived from the Latin word "commissura," meaning "junction" or "connection." Overall, the spelling of "periportal commissura" reflects its anatomical location and function.
The term "periportal commissura" refers to a specific anatomical region within the human or animal body, particularly in relation to the liver. It describes a structure that can be found in the hepatic (liver) tissue, specifically in the vicinity of the portal area.
The periportal commissura is essentially a network of connective tissue fibers, blood vessels, and bile ducts located at the periphery or border of the portal triads. Portal triads are distinct anatomical units within the liver that consist of a branch of the hepatic artery, a branch of the hepatic portal vein, and a bile duct. These structures are essential for the proper functioning of the liver, as they transport nutrients, oxygenated blood, and bile to and from the hepatic cells.
The periportal commissura acts as a bridge or connection between adjacent portal triads, helping to facilitate the flow of blood and bile within the liver. This network of connective tissue also provides structural support to the liver tissue by strengthening its architecture. Additionally, it assists in the distribution of essential substances, such as oxygen and nutrients, to the liver cells, as well as the removal of waste products from them.
In summary, the periportal commissura is a specialized region within the liver that serves as a connective tissue network, providing structural support and facilitating the flow of blood and bile between adjacent portal triads.

The term "periportal commissura" is a combination of two words: "periportal" and "commissura".
- "Periportal" is derived from the Greek roots "peri-", meaning "around" or "surrounding", and "portal", which refers to the portal vein. In medical terminology, the word "periportal" generally describes structures or regions adjacent to the portal vein or portal triad within the liver.
- "Commissura" is derived from the Latin word "commissura", which means "union" or "connection". In anatomy, the term "commissura" typically refers to a structure that connects two parts or regions.
Therefore, the term "periportal commissura" can be understood as a connecting structure or region located around the portal vein in the liver. It likely denotes a specific anatomical feature in this particular context.
