Quizplus · Accepted Answer

The structure indicated by a black open arrow in a typical anatomical diagram, when referring to the context of spinal anatomy, is most likely the Posterior Longitudinal Ligament. This ligament runs along the posterior aspect of the vertebral bodies inside the vertebral canal, contrasting with the Anterior Longitudinal Ligament which is located on the anterior aspect of the vertebral bodies. The Epidural fat is located in the epidural space, surrounding the dural sac but not structured like a ligament, and the Ligamentum flavum connects the laminae of adjacent vertebrae on the posterior side of the spinal column, but it is not positioned directly adjacent to the vertebral bodies as the posterior longitudinal ligament is.
