Germinal matrix - Wikipedia
In anatomy, the germinal matrix is a highly cellular and highly vascularized region in the brain out from which cells migrate during brain development. The germinal matrix is the source of both neurons and glial cells and is most active between 8 and 28 weeks gestation .
Germinal Matrix - an overview | ScienceDirect Topics
The germinal matrix is the area in the developing fetal brain that gives rise to the neuronal cells which will later constitute the grey matter of the brain. The germinal matrix first appears at 7 weeks of gestational age and increases in size to the 23rd week, when it lies adjacent to the ventrolateral wall of the lateral ventricles. 31 After ...
A brain region-specific neural pathway regulating germinal matrix ...
Germinal matrix (GM), a key primordium for the brain reward circuitry, is unique among brain regions for its distinct pace of angiogenesis and selective vulnerability to hemorrhage during development. A major neonatal condition, GM hemorrhage can lead to cerebral palsy, hydrocephalus, and mental retardation.
Germinal Matrix - an overview | ScienceDirect Topics
The germinal matrix is a neural stem cell population that is adjacent to the lateral ventricles as a subependymal layer and gives rise to sequentially differentiated neuronal and glial precursors that migrate to their homes in the cerebrum (Fig. 2.19A). The germinal matrix is prominent in early brain development and does not begin to thin out ...
Anatomic Analysis of Blood Vessels in Germinal Matrix
2004年7月1日 · We measured vessel density, percentage of blood vessel area, mean surface area, length, breadth, perimeter, radius, and shape of blood vessels in coronal sections of the GM, gray matter, and white...
Development and pathology of the germinal matrix
2021年1月1日 · The germinal matrix (GM) is a delicate web of densely packed blood vessels and neural stem/progenitor cells (NSPCs) found adjacent to the ependymal lining of the ventricular system. There, in the thalamostriate groove, the GM generates both cortical neurons and glia.
Germinal matrix | Radiology Reference Article - Radiopaedia.org
2020年5月29日 · The germinal matrix is an embryological structure in the fetal brain which is only seen in the fetus and in premature neonates. It is the most vulnerable area of the fetal brain and associated pathology carries significant mortality and morbidity. The germinal matrix is usually seen from 8-28 weeks of gestation.
Atlas-based Segmentation of the Germinal Matrix from in Utero …
We describe an approach to atlas-based segmentation of the fetal brain with particular focus on the delineation of the germinal matrix, a transient structure related to brain growth. We segment 3D images reconstructed from in utero clinical MR scans and measure volumes of different brain tissue classes for a group of fetal subjects at ...
Germinal Matrix - (Anatomy and Physiology I) - Fiveable
The germinal matrix is a highly vascular region of the developing brain that serves as the primary site of neurogenesis during fetal development. It is located in the ventricular and subventricular zones of the cerebral hemispheres and is responsible for the production of new neurons and glial cells that will eventually migrate to their final ...
Anatomic analysis of blood vessels in germinal matrix ... - PubMed
The germinal matrix (GM) located in the thick subependymal cell layer of the thalamostriate groove is a major site of cerebral hemorrhage in premature infants. Comparing the morphology of vasculature among GM, gray and white matter of the brain may help in understanding the pathogenesis of GM hemorr …
