2022年12月5日 · Confluence of Sinuses (confluens sinuum) The confluence of sinuses (torcular of Herophilus or torcula) is a dural venous sinus that appears as a dilation at the posterior end of the superior sagittal sinus.It is located on the caudal aspect of the brain, around the internal occipital protuberance of the occipital bone.. Functionally, this vessel represents a junction between the superior ...

The confluence of sinuses shows significant variation. [1] Most commonly, there is a continuous connection between all of the sinuses. [1] [2] A very common variant is the superior sagittal sinus only draining into the right transverse sinus - more rarely, it may also only drain into the left transverse sinus.[1] [2] Another variation involves a continuous connection, but …

2023年6月18日 · The confluence of sinuses (Latin: confluens sinuum), also known as the torcular Herophili and occasionally simply torcula, is the junction of the following dural venous sinuses: superior sagittal sinus. straight sinus. occipital sinus. transverse sinuses. The anatomy is highly variable and three types can be distinguished:

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. The superior sagittal sinus often drains into (either exclusively or predominantly) one ...

2025年1月23日 · The confluence of sinuses (also known as the torcular Herophili) is a crucial venous structure in the brain where several major dural venous sinuses converge. It serves as a meeting point for venous blood draining from various regions of the brain, directing it toward the larger veins that transport blood out of the cranial cavity. ...

2024年10月1日 · Paired Sinuses. There are five main paired dural venous sinuses, located on the left and right side of the cranial cavity. Transverse Sinuses. The right and left transverse sinuses (also known as lateral sinuses) are formed at the confluence of sinuses by the convergence of the superior sagittal, straight and occipital sinuses.. They …

The confluence of sinuses (confluens sinuum) is formed by the junction of the straight sinus, the superior sagittal sinus, and both transverse sinuses (Figs. 8.21 and 8.22). Rather than a true confluence, the superior sagittal sinus usually drains into the right transverse sinus and the straight sinus into the left.

The confluence of sinuses (Fig. 7.58) is formed by two transverse sinuses connected by small venous channels near the internal occipital protuberance. The occipital sinus, a small venous sinus extending from the foramen magnum, drains into the confluence of sinuses. It lies along the falx cerebelli and connects the vertebral venous plexuses to ...

2020年1月1日 · The torcular Herophili (confluence of sinuses) is a highly variable structure that constitutes a vital part of the network of dural venous sinuses (Fig. 7.1, Fig. 7.2, Fig. 7.3, Fig. 7.4, Fig. 7.5).The torcular Herophili is defined historically as the intersection of the superior sagittal sinus (SSS), the straight sinus (StS), the occipital sinus …

2024年9月30日 · The torcula, also known as the confluence of sinuses or torcular Herophili, is a fascinating anatomical structure that serves as a meeting point for several major venous sinuses in the brain. Named after the ancient Greek physician Herophilus, who first described it in the 3rd century BCE, the torcula is like a bustling roundabout where blood ...
