Diploic Canals [Canales Diploici, Pna, Jna; Canales Diploici (Brescheti), Bna; Syn.: Brechet Channels, Diploetic Channel]

Diploic Channels: Description and Role in the Organism

Diploic canals (Canales Diploici) are bone canals that pass through the spongy substance of the bones of the cranial vault (diploe). They serve to transport diploic veins, which receive blood from the internal venous sinuses of the brain and exit through the venous openings of the skull.

Diploic canals were discovered by the French anatomist Camille Breschet in 1829, and are therefore sometimes called Brescheti's canals. They may also be designated as diploetic channels.

There are several types of diploic canals. Some of them, such as Pna (posterior nasal aperture) and Jna (jugular notch aperture), are found in the nose and neck area, respectively. Others, such as Bna (bregmatic-nasal aperture), are found on the top of the skull.

The role of diploic channels in the body is still not fully understood. However, it is known that the diploic veins that pass through these channels can be involved in the spread of infections within the skull, such as sinusitis (inflammation of the sinuses) or meningitis (inflammation of the meninges). Additionally, diploic canals can be used in medical procedures such as biopsies or surgeries.

In conclusion, diploic canals are bony canals that pass through the cancellous bones of the calvarium and serve to transport diploic veins. The role of these channels in the body is still not fully understood, but they may be involved in the spread of infections within the skull and used in medical procedures.



The diploic canals [Canales Diploma, PDCA, BPDCA, BC], also known as diplomatic canals or Breches canals, are one of the main components of the blood flow system in the head, used to transport nutrients and oxygen to the entire surface of the brain. They are located in the area of ​​the ceiling of the skull where the cranial fossae meet and are connected to the venous system through the diploic sinuses.

The diploic canal is present in all mammals, including humans. It consists of a dense system of blood-filled canals, which are located at the bottom of the anterior and posterior cranial fossae and are completely separated from them by the median strip of the spongy
