What is the petrosal vein?

The superior petrosal vein, also known as Dandy’s vein is part of the venous drainage system in the posterior cranial fossa, draining the anterior aspect of the cerebellum and brainstem.

What does the superior petrosal sinus do?

The superior petrosal sinus drains many veins of the brain, including superior petrosal veins, some cerebellar veins, some inferior cerebral veins, and veins from the tympanic cavity.

Where does the greater petrosal sinus drain?

The superior petrosal sinus is one of the dural venous sinuses and drains the cavernous sinus. It courses posterolaterally to drain into the sigmoid sinus at the continuation of the transverse sinus. It runs along the superior aspect of the petrous temporal bone.

What are brain sinuses?

The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous channels found between the endosteal and meningeal layers of dura mater in the brain.

What is Meckel’s cave?

Meckel’s cave is a dural recess in the posteromedial portion of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the prepontine cistern and the cavernous sinus, and houses the Gasserian ganglion and proximal rootlets of the trigeminal nerve.

What is frontal sinusitis?

Frontal sinusitis is inflammation or infection of the sinuses located just behind the eyes and in the forehead. The sinuses are a system of connected hollow cavities in the face that contain air and a thin layer of mucus. All sinuses produce mucus that moisturizes the airways and drains into the nasal passages.

What is venous sinus?

venous sinus, in human anatomy, any of the channels of a branching complex sinus network that lies between layers of the dura mater, the outermost covering of the brain, and functions to collect oxygen-depleted blood. Unlike veins, these sinuses possess no muscular coat.

What veins drain into cavernous sinus?

The cavernous sinuses receive blood from the superior ophthalmic vein of the orbit, along with the superficial middle cerebral vein of the brain, and other sources. They drain through the transverse sinus, internal jugular vein, and facial vein.

What does transverse sinus drain into?

The transverse sinuses are formed by the tentorium cerebelli and drain into the right and left sigmoid sinuses. They drain from the confluence of sinuses (by the internal occipital protuberance) to the sigmoid sinuses, which ultimately connect to the internal jugular vein.

What is the difference between a sinus and a vein?

Unlike veins, these sinuses possess no muscular coat. Their lining is endothelium, a layer of cells like that which forms the surface of the innermost coat of the veins. The sinuses receive blood from the veins of the brain and connect directly or ultimately with the internal jugular vein.

Where are the brain venous sinuses located?

Where does the superior petrosal sinus drain into?

Which is sinus drains the petrous temporal bone?

Superior petrosal sinus. The superior petrosal sinus is one of the dural venous sinuses and drains the cavernous sinus, posterolaterally to the transverse sinus. It runs along superior aspect of the petrous temporal bone. It receives:

Is there an MRI cross sectional Atlas of the brain?

Anatomy of the brain (MRI) – cross-sectional atlas of human anatomy The module on the anatomy of the brain based on MRI with axial slices was redesigned, having received multiple requests from users for coronal and sagittal slices.

Who are the patients of MRI imaios module?

This module is intended for all physicians and non-physicians with an interest in neuroanatomy and medical imaging, particularly for general practitioners and specialists in neurology, neurosurgery, anatomy and neurosciences, as well as speech pathologists and psychomotor therapists.
