What does transverse sinus mean?
The transverse sinus is a tunnel-shaped anatomical space between the great vessels and the roof of the LA, connecting the left and right sides of the pericardial cavity. From: Cardiac Electrophysiology: From Cell to Bedside (Seventh Edition), 2018.
What is transverse sigmoid sinus?
The sigmoid sinus is actually a pair of two sinuses (right and left) that enable veins to spread from the middle of the head downwards. This dual structure is considered an extension of the transverse sinus, which lies in the hind portion of the brain.
What is the function of the transverse sinus?
The function of the transverse sinus is to collect the blood from the veins of the cerebellum and inferior surface of the brain. Delivering this blood to the sigmoid sinus, the transverse sinus belongs to the system of the internal jugular vein.
What is transverse sinus hypoplasia?
Hypoplasia was defined as a transverse sinus diameter less than 50[percnt] of the cross-sectional diameter of the lumen of the distal superior sagittal sinus.
What is the transverse sinus of the brain?
The transverse sinuses (left and right lateral sinuses), within the human head, are two areas beneath the brain which allow blood to drain from the back of the head. They run laterally in a groove along the interior surface of the occipital bone.
Where is the transverse venous sinus located?
The dural venous sinuses are venous channels in the cranium that drain blood and cerebrospinal fluid circulating from the brain into the vascular system via the internal jugular veins. The transverse sinus is a dural venous sinus present in the posterior aspect of the cranium.
What is coronary sinus?
The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.
Is transverse sinus stenosis rare?
Moreover, transverse sinus stenosis may also be found in about one-third of the general population (10, 11).
What are sinuses in the heart?
The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart’s posterior (rear) surface between the left ventricle and left atrium.
How are transverse sinuses formed in the heart?
Pericardial reflections surrounding the venae cavae and pulmonary veins give rise to the oblique sinus, and the transverse sinus is formed by pericardial reflections around the proximal portions of the pulmonary artery and ascending aorta (Fig. 23-1).
Is coronary sinus the same as coronary artery?
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior venae cavae….

What does sigmoid sinus mean?
Sigmoid sinus. The sigmoid sinus (latin: sinus sigmoideus) is a S-shaped dural venous sinus that extends beneath the temporal bone from the mastoid process to the jugular foramen. The sigmoid sinus is a continuation of the transverse sinuses, arising where the transverse sinus leaves the tentorium cerebelli.

What does transverse colon do in the digestive system?
The transverse colon’s function is to extract water and nutrients from digested foods or materials that pass through the digestive tract. The transverse colon is the longest section of the colon. Its location is across the abdomen, and it forms a connection between the ascending colon and descending colon.
Is there a mastoid sinus?
It is more like the bones of the face which house the sinuses. In fact, the mastoid is essentially the sinus of the ear. Sound resonates in the air-filled spaces of the ear including the mastoid. The spaces are lined with mucosa like the lining of your mouth, lungs, or stomach.
