Alexander Monro, secundus (www.whonamedit.com) After only one session of this arrangement Monro primus petitioned the town council, the patrons of the university, to appoint his son joint professor of anatomy, and his request was backed by a certificate from the students of his son’s evening class testifying to their satisfaction with his teaching. Monro extended his attacks to include Hewson, his own former pupil and a colleague of Hunter, who in 1767 had recommended the operation of paracentesis of the thorax in traumatic pneumothorax and at the same time had published his own discovery of the existence of lacteals and lymphatics in non.mallaians. Monro secundus’ earlier publications were largely polemical, and it was not until he had been teaching for twenty-five years that his three main contributions to medical literature appeared. www.whonamedit.com /doctor.cfm/941.html   (1868 words)

Alexander Monro, secundus Biography | World of Anatomy and Physiology Three generations of Alexander Monros were professors of anatomy at the University of Edinburgh in unbroken succession from 1720 to 1846. Monro secundus, the greatest of the three, is chiefly remembered for discovering and accurately describing the foramen interventriculare, or "foramen of Monro," an important passage connecting the lateral and third ventricles of the brain. Knowledge of the communicative function of the foramen of Monro became crucial for the new science of neuroradiology early in the twentieth century because, for neurosurgeons like Walter Dandy (1886-1946), it paved the way for useful neurological diagnostic techniques such as pneumoventriculography, which injects air as an x-ray contrast medium directly into the ventricles. www.bookrags.com /biography/alexander-monro-secundus-wap   (422 words)

TRANSCALLOSAL APPROACH TO COLLOID SYST Colloid cysts are slowly growing lesions, probably of endodermal origin, and usually founding the anterior third ventricle close to the foramen of Monro, but other locations, such as, the roof of the third ventricle, the columns of the fornix, or the choroid plexus, are possible. When the foramen of Monroe is enlarged which is so in the majority of the cases that the author operated upon, the lesion can be removed by the transforaminal approach. The foramen of Monroe may appear narrow on first appearance and there may be a bulge posteriorly. www.thamburaj.com /colloid_cyst.htm   (2721 words)

Interventricular foramina - Wikipedia, the free encyclopedia In the brain, the interventricular foramina (or foramina of Monro) are channels that connect the paired lateral ventricles with the third ventricle at the midline of the brain. The crescent-shaped interventricular foramina are located on the medial and inferior aspect of the lateral ventricles. The foramina were named after the Scottish physician Alexander Monro, who first described the structures in his 1783 publication, Observations on the Structure and Functions of the Nervous System. en.wikipedia.org /wiki/Interventricular_foramina   (304 words)

Gray, Henry. 1918. Anatomy of the Human Body. Page 816 At the junction of the roof and anterior wall of the ventricle, and situated between the thalami behind and the columns of the fornix in front, is the interventricular foramen (foramen of Monro) through which the third communicates with the lateral ventricles. Each lateral wall consists of an upper portion formed by the medial surface of the anterior two-thirds of the thalamus, and a lower consisting of an upward continuation of the gray substance of the ventricular floor. The columns of the fornix curve downward in front of the interventricular foramen, and then run in the lateral walls of the ventricle, where, at first, they form distinct prominences, but subsequently are lost to sight. www.bartleby.com /107/pages/page816.html   (489 words)

MedFriendly.com: Lateral ventricles The anterior horn is positioned in front of the interventricular foramen, which connects the lateral ventricles to the third ventricle. The area that connects the lateral ventricles with the third ventricle is known as the interventricular foramen of Monro (also known as the interventricular foramen and the foramen of Monro). The choroid plexus, which are the blood vessels in the lateral ventricle that produce cerebrospinal fluid, are found in the central part of the lateral ventral and the inferior horn, but not in the anterior or posterior horns. www.medfriendly.com /lateralventricles.html   (1084 words)

These lesions appear as round or oval lesions in the anterior and superior portion of the third ventricle at the level of the foramen of Monro. Since there are no pathognomonic signs and symptoms for colloid cysts, the correct diagnosis and treatment depends on the careful integration of history, neurologic examination, and imaging studies. neurosurgery.ucla.edu /Diagnoses/BrainTumor/BrainTumorDis_8.html   (627 words)

NursingCredits.com: Nursing certification credits for Nursing technicians and professionals Cerebral spinal fluid is mainly formed by the choroid plexus, which are infoldings of blood vessels covered by a thin tissue called pia and are located in the four ventricles of the brain — the largest of which are found in the lateral ventricles. From the fourth ventricle, the CSF then passes through the foramen of Luschka and the foramen of Magendie to enter the subarachnoid space that externally bathes the cerebral structures of the brain and spinal cord. Other causes for communicating hydrocephalus include obliteration of the superior sagittal sinus (where most of the arachnoid granules are located), absence of the subarachnoid granules, subarachnoid hemorrhage (clotted blood may block the subarachnoid granules), and choroid plexus papilloma. e-edcredits.com /nursingcredits/article.asp?TestID=34   (3239 words)

Cerebrospinal Fluid   (Site not responding. Last check: 2007-10-09) The CSF is formed in the lateral ventricles, circulates through the interventricular foramens into the third ventricle, and then via the cerebral aqueduct into the fourth ventricle. Here the fluid scapes via the lateral apertures of the fourth ventricle and the medial foramen of the fourth ventricle into the subaracnoid spaces, where it difuses over the brain and spinal cord. The fluid flows through the interventricular foramen (of Monro) into the third ventricle, is augmented by fluid formed by the choroid plexus of this ventricle, and passes through the cerebral aqueduct (of Sylvius) to the fourth ventricle, which also possesses a choroid plexus. www.cerebromente.org.br /n02/fundamentos/circulation_i.htm   (420 words)
