- For the transverse pericardial sinus, see: pericardial sinus.
The transverse sinuses (left & right lateral sinuses), within a human head, are 2 areas beneath the brain, which allow blood veins to span the area, from the back of the head towards the nose. They drain from the straight sinus and superior sagittal sinus (along the top and back of the brain) to the sigmoid sinuses (at the center of the head), at the internal jugular vein. See diagram (at right): labeled under the brain as "SIN. TRANS." (for Latin: sinus transversus).
The transverse sinuses are of large size and begin at the internal occipital protuberance; one, generally the right, being the direct continuation of the superior sagittal sinus, the other of the straight sinus.
Each transverse sinus passes lateralward and forward, describing a slight curve with its convexity upward, to the base of the petrous portion of the temporal bone, and lies, in this part of its course, in the attached margin of the tentorium cerebelli; it then leaves the tentorium and curves downward and medialward to reach the jugular foramen, where it ends in the internal jugular vein.
In its course it rests upon the squama of the occipital, the mastoid angle of the parietal, the mastoid part of the temporal, and, just before its termination, the jugular process of the occipital; the portion which occupies the groove on the mastoid part of the temporal is sometimes termed the sigmoid sinus.
The transverse sinuses are frequently of unequal size, with the one formed by the superior sagittal sinus being the larger; they increase in size as they proceed, from back to center.
On transverse section, the horizontal portion exhibits a prismatic form, the curved portion has a semicylindrical form.
They receive the blood from the superior petrosal sinuses at the base of the petrous portion of the temporal bone; they communicate with the veins of the pericranium by means of the mastoid and condyloid emissary veins; and they receive some of the inferior cerebral and inferior cerebellar veins, and some veins from the diploë.
The petrosquamous sinus, when present, runs backward along the junction of the squama and petrous portion of the temporal, and opens into the transverse sinus.
