Monroe's Furrow

Monroe's groove, syn. Monroe's duct (lat. sulcus Monro), a sigmoid fissure between the bodies of the anterior cerebellar peduncles and the anterior surface of the cerebral hemisphere, connecting the posterior part of the cerebellar velum with the superior medullary velum. Identified and described in 1925 by the English neurologist Richard Monroy (R. J. Monro). Monroev B. extends at an angle from the fibers of the clivus of the corpus callosum (falcibus corporis callosi) posteriorly and downward to the posterior end of the rhomboid fossa. Its length ranges from 8 to 12 mm. The periosteum and subcutaneous tissue layer are weakly expressed or completely absent. In the MB there is a single cerebral artery, which is involved in the development of a Cerebro-Ponto-Spinal Cord defect of a vascular nature. Monro's hole (foramen Monro) - back of Sil
