Anatomical term for neuroanatomy.The tentorium cerebellum or tentorium (Latin for « the tent of the cerebellum ») is An extension of the dura that separates the cerebellum from the lower occipital lobe. https://en.wikipedia.org › Wiki › Cerebellar_tentorium

. It spans from the corpus cavernosum to the transverse sinus The transverse sinus (lateral sinus) is a pair of veins that run through the tentoriumBoth sinuses begin at the intraoccipital eminence of the occipital bone, and they terminate by giving off the ipsilateral sigmoid sinus. https://www.kenhub.com › Libraries › Anatomy › Transverse Sinus

It passes through the superficial groove on the upper border of the petrosal temporal bone.

What is the petrosal sinus?

The petrosal sinus is part of the dural venous sinus system Drains the venous blood and cerebrospinal fluid circulating in the cranial cavity. The dural venous sinus system drains into the internal jugular vein and further into the cardiovascular circulation via the superior vena cava.

Are the superior petrosal sinuses paired?

Paired superior petrosal sinuses leave Back The cavernous sinus joins the transverse sinus along the posterolateral aspect of the superior border of the petrosal temporal bone.

Where does the superior petrosal sinus drain?

The superior petrosal sinus is one of the dural venous sinuses that drain the cavernous sinus.It extends posterior lateral to flow in Sigmoid sinus at the continuation of the transverse sinus. It runs along the upper side of the temporal bone.

How many superior sagittal sinuses are there?

The superior sagittal sinus is usually divided into three parts: Anterior (cecal foramen to bregma), middle (bregma to lambda), posterior (lambda to confluence). The section is triangular in shape, narrow in the front and gradually larger in the back.
