The germinal matrix is the source of both [[neuron]]s and [[glial cell]]s and is most active between 8 and 28 weeks [[gestation]]. It is a fragile portion of the [[brain]] that may be damaged leading to an [[intracranial hemorrhage]] known as a [[germinal matrix hemorrhage]], which is the most common cause of second trimester spontaneous abortions. ==See also== *[[Intraventricular hemorrhage]] [[Category:Head and neck]] {{developmental-biology-stub}} {{neuroscience-stub}}
