The germinal matrix is an embryological structure in the fetal brain which is only seen in the fetus and in premature neonates. This layer is traversed by a rich network of delicate vessels that have no structural support and lack autoregulation which makes them susceptible to fluctuations of.
English term or phrase. Germinal matrix also called subependymal germinal matrix is a thick cellular layer of immature cells or neuroblasts neuronal and glial precursors under the ependymal lining of the ventricles which is located above the caudate nucleus in the floor of the lateral ventricle and caudothalamic groove where neuroblasts migrate from between 10 and 20 weeks and becomes the source of glioblasts in the. Neue Studien zeigen jedoch dass eine GMH mit einer schlechteren neurologischen Entwicklung assoziiert ist Vasileiadis Pediatrics 2004.
Germinal Matrix Hemorrhage -Intraventricular hemorrhage IVH is a bleed of multifactorial etiology involving the highly vascular and delicate neuro-glial precursors in the developing brain. When cell division and migration are complete the germinal matrix progressively decreases in size with regression being almost complete by. Cranial ultrasonography demonstrates a germinal matrix and intraventricular hemorrhage.
Gross anatomy The germinal matrix is usually seen from 8. The germinal matrix is a thick cellular layer of immature cells neuronal and glial precursors under the ependymal lining of the ventricles.

The germinal matrix lies within the caudothalamic groove the space between the caudate head and the thalamus. The germinal matrix is the site of proliferating neuronal and glial precursors in the developing brain which is located above the caudate nucleus in the floor of the lateral ventricle and caudothalamic grooveThe germinal matrix contains a rich network of fragile thin-walled blood vessels. In anatomy the germinal matrix is a highly cellular and highly vascularized region in the brain from which cells migrate out during brain development.
For many years cerebellar development after preterm birth has been poorly investigated and has been studied without taking germinal matrix-intraventricular haemorrhage into account.

The germinal matrix cells can be seen in the CSF of neonates or premature infants. De germinal matrix is een belangrijke site voor de ontwikkeling van de hersenen omdat de zenuwcellen of neuronen worden daar geproduceerd die gaan op gebieden zoals de cortex of de grijze stof te vormen. Germinal matrix hemorrhage is a frequent complication of prematurity and can be associated with adverse neurodevelopmental outcome depending on its severity.
Less than 20 cases of intracranial hemorrhage have been diagnosed prenatally.
