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 vertebra showing central stenosis and lateral recess stenosis. Specialty: Orthopedics: Symptoms: Pain, numbness, or weakness in the low back, buttocks, or legs typically worsened with prolonged walking or standing and relieved with sitting or lying down: Usual onset: Gradual (months to years) Types: Congenital, acquired: Causes
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).
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 ...
The right lateral paracolic gutter. The left medial paracolic gutter. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. The main paracolic gutter lies lateral to the colon on each side.
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]
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).
