- After it passes through the foramen magnum and perforates dura mater, the vertebral artery travels along the medulla oblongata, posterior to the hypoglossal nerve. (T/F?)
- It joins the vertebral artery of the opposite side at the pontomedullary sulcus to form the basilar artery. (T/F?)
- The anterior spinal artery if formed from two branches that originate from corresponding vertebral arteries. (T/F?)
- The posterior spinal artery usually originates from the anterior inferior cerebellar artery and sometimes directly from the vertebral artery. (T/F?)
- The posterior inferior cerebellar artery is the largest branch of the vertebral artery. (T/F?)
