DIPLOIC VEIN Meaning and
Definition
-
Diploic veins are thin-walled blood vessels found within the diploë, a spongy layer of bone located between the inner and outer tables of the cranial bones. More specifically, they are present in the diploic space, a network of vascular channels or sinuses formed by these veins. These channels traverse the diploë and connect with other veins in the skull, such as the superior sagittal sinus, the pericranial veins, and the emissary veins.
The diploic veins serve as an important drainage system, responsible for collecting deoxygenated blood from the cranial bones and facilitating its return to the venous circulation. They help to regulate the intracranial pressure, ensuring constant blood flow within the skull. The diploic veins also aid in heat regulation, as the circulation of blood within the diploë contributes to the thermal exchange between the brain and the outer environment.
In certain clinical scenarios, such as cranial trauma or infections, the diploic veins may become dilated or engorged, resulting in an abnormal increase in intracranial pressure. This can lead to symptoms like headaches, vision disturbances, and neurological deficits. Conversely, a decrease in diploic vein function or obstruction may lead to impaired venous drainage, potentially causing intracranial hypertension or other complications.
In summary, diploic veins are blood vessels situated within the diploë of cranial bones, forming a network of channels that drain deoxygenated blood from the skull. They play a crucial role in maintaining intracranial pressure and facilitating heat exchange within the cranium.

Etymology of DIPLOIC VEIN
The term "diploic vein" is derived from Latin and Greek roots.
The word "diploic" comes from the Greek word "diploos" meaning "double". It refers to the fact that this type of vein is found within the diploë, which is the spongy layer of cancellous bone that separates the outer and inner plates of the skull. The diploic veins are located within this layer.
The word "vein" comes from the Latin word "vēna", which means "a blood vessel". Veins are responsible for carrying deoxygenated blood back to the heart.
Thus, the term "diploic vein" combines the Greek roots indicating the location within the diploë and the Latin root referring to its role as a blood vessel. It is used to describe the veins found within the diploë layer of the skull.
