(FRAME-INFO (STRING "Spinal Veins. \(Image modified from N.B. Everett, Functional Neuroanatomy. Lea & Febiger 1971, with permission of Williams & Wilkins\). Blood drains from the spinal cord via six longitudinal venous channels: the unpaired anterior and posterior spinal veins and the paired anterolateral and posterolateral veins. Intramedullary veins drain blood from the white and gray matter into these channels. The longitudinal veins drain into various segmental veins along the length of the cord: the vertebral veins in the cervical region, the intercostal veins in the thorax, and the lumbar and sacral veins in the abdomen and pelvis.
