What is Luschka and Magendie?

What is Luschka and Magendie?

The foramen of Magendie (also called median aperture) is one of the foramina in the ventricular system and links the fourth ventricle and the cisterna magna. The two other openings of the fourth ventricle are termed the foramen of Luschka also called (lateral apertures), one either left and right.

What is atresia of foramina of Magendie and Luschka?

Abstract. Atresia of the foramina of Magendie and Luschka is a rare cause of obstructive hydrocephalus. Although this condition has been classically treated by CSF shunting, recent treatments have also included endoscopic third ventriculostomy.

What is the function of foramen of Luschka?

Results: The foramina of Luschka are paired apertures located in the lateral recesses of the fourth ventricle, within the posterior cranial fossa. The foramina of Luschka are of importance clinically as their blockage can disrupt the flow of cerebrospinal fluid leading to the development of hydrocephalus.

What does the foramen of Luschka communicate with?

Two lateral apertures (foramen of Luschka) also open into the cisterna magna. A choroid plexus forms in each of the developing ventricles as local blood vessels interact with the ependymal cells that line the wall of the ventricles. This allows the choroid plexus to secrete CSF directly into the ventricular system.

Where does foramen of Luschka go?

They are located at the lateral-most aspect of the fourth ventricle and drain into the subarachnoid space at the cerebellopontine angle cistern immediately posterior to the root of the glossopharyngeal (IX) nerve.

Why is it called Dandy Walker syndrome?

The syndrome is named after physicians Walter Dandy and Arthur Walker, who described associated signs and symptoms of the syndrome in the 1900s. The malformations often develop during embryonic stages.

What is the function of the Cisterna Magna?

The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata. Cerebrospinal fluid produced in the fourth ventricle drains into the cisterna magna via the lateral apertures and median aperture….

What is the Tela Choroidea?

The tela choroidea is the thin, highly vascularized, loose connective tissue portion of pia mater that gives rise to the choroid plexus. Thus, it is basically the lamina propria of the ependyma and lies directly adherent to it, without any tissue in between the two 6.
