Germinal matrix zone

The germinal matrix zone is a cell-rich area in the brain that is described in neuroradiology and has a strong blood supply . In this part of the brain adjacent to the lateral ventricles , nerve cells and glial cells are formed through mitosis .

anatomy

The germinal matrix zone is located in the subependymal (below the ependymal ) layers of the two lateral or first and second ventricles (cerebral chambers) .

function

After the affected neuron has been formed through mitosis, it migrates to the region of the cerebral cortex . Thus the germinal matrix zone is responsible for the formation of neurons and glial cells , which later migrate into the cortex . The production of the affected cells begins in the seventh week in the brain of the fetus . After another week, the cells begin to migrate in the cortex. The germinal matrix is ​​particularly active during the 8th and 24th weeks of the fetus.
