Osmosis video - Adult brain tumors: Pathology review

Adult brain tumors are tumors that occur in adults. The most common type of adult brain tumor is glioma, which arises from the glial cells that support the nerve cells in the brain. Other types of adult brain tumors include meningiomas (tumors that arise from the meninges, which are the membranes surrounding the brain and spinal cord), schwannomas (tumors that arise from Schwann cells, which support the nerve fibers), and astrocytomas (tumors that arise from star-shaped cells called astrocytes).
