What is Trolard vein?
The vein of Trolard, or the superior anastomotic vein, is the primary connecting midline afferent and usually enters into the SSS in the postcentral region. Inferior cerebral veins are cortical bridging veins that primarily channel into the basal sinuses or the deep venous system.
Where is the vein of Trolard?
The superior anastomotic vein (or vein of Trolard) is the largest superficial vein on the lateral surface of the parietal or frontal lobe that connects the superior sagittal sinus and the superficial middle cerebral vein (of Sylvius). It usually runs in the post-central sulcus draining the adjacent cortex.
Where does the inferior anastomotic vein drain?
Thus, the inferior anastomotic vein drains into the transverse sinus and retrogradely into the opposite jugular system.
Where is vein of Labbé?
temporal lobe
The vein of Labbé (inferior anastomotic vein) is part of the superficial venous system of the brain. The vein of Labbé is the largest channel that crosses the temporal lobe between the sylvian fissure and the transverse sinus and connects the superficial middle cerebral vein and the transverse sinus.
What are anastomotic veins?
Which of the 3 cerebral arteries supplies the Wernicke’s area?
the middle cerebral artery
Blood Supply and Lymphatics Wernicke area receives its vascular supply from the inferior temporal branch of the middle cerebral artery. The temporal lobe drains blood via 2 primary routes. The first involves the anterior drainage of the temporal lobe via the superficial middle cerebral vein.
What is the main vein that drains the brain?
jugular vein
jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava. The main vessels are the external jugular vein and the interior jugular vein.
What is a torcula?
The confluence of sinuses, torcular herophili, or torcula is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus. It is found deep to the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinuses.
What is emissary vein?
The emissary veins are valveless vessels which connect the superficial veins of the scalp with deeper veins, e.g. diploic veins of the skull bones.
What is the meaning of anastomotic?
An anastomosis is a surgical connection between two structures. It usually means a connection that is created between tubular structures, such as blood vessels or loops of intestine. For example, when part of an intestine is surgically removed, the two remaining ends are sewn or stapled together (anastomosed).
What supplies Broca’s and Wernicke’s area?
middle cerebral artery
What is the torcular Herophili?
The torcular Herophili (confluence of sinuses) is a highly variable structure that constitutes a vital part of the network of dural venous sinuses. The torcular Herophili is defined historically as the intersection of the superior sagittal sinus, the straight sinus, the occipital sinus, and the two transverse sinuses.
