The lateral recess or lateral recess of fourth ventricle, is a projection of the fourth ventricle which extends to the lateral border of the brainstem at the pontomedullary junction. [1] [2] At this point the fourth ventricle is at its widest. [1] The lateral recess on each side opens into a lateral aperture (foramen of Luschka) that opens into ...
The lateral aperture, lateral aperture of fourth ventricle or foramen of Luschka (after anatomist Hubert von Luschka) [1] is an opening at the lateral extremity of either lateral recess of the fourth ventricle opening anteriorly [2] into (sources differ) the pontine cistern [2] /lateral cerebellomedullary cistern at cerebellopontine angle. [3]
Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
The horizontal portion extends transversely across the inferior peduncle, below the striae medullares, and roofs in the lower and posterior part of the lateral recess; it is attached by its lower margin to the inferior peduncle, and partly encloses the choroid plexus, which, however, projects beyond it like a cluster of grapes; and hence this ...
It also contains two cranial nerves – the vestibulocochlear nerve and the facial nerve; the cerebellar flocculus and the lateral recess of the fourth ventricle. [ citation needed ] Clinical significance
Lateral wall of nasal cavity. (Pharyngeal recess labeled at bottom right.) ... At the base of this recess is the retropharyngeal lymph node (the node of Rouvière).
The third ventricle is one of the four connected cerebral ventricles of the ventricular system within the mammalian brain.It is a slit-like cavity formed in the diencephalon between the two thalami, in the midline between the right and left lateral ventricles, and is filled with cerebrospinal fluid (CSF).
