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 ...
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can ...
X-rays are performed followed by a CT scan of the spine to help see narrowing of the spinal canal. This is a very effective study in cases of lateral recess stenosis. It is also necessary for patients in which MRI is contraindicated, such as those with implanted pacemakers. [citation needed]
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]
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 ...
In the human brain, the rhomboid fossa is divided into symmetrical halves by a median sulcus which reaches from the upper to the lower angles of the fossa and is deeper below than above.
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.
It is a slight elevation in the floor of the inferior recess of the fourth ventricle, beneath which is the nucleus of origin of the twelfth cranial nerve. References [ edit ]
