(FRAME-INFO (STRING "Spinal Cord Specimen. \(Image modified from N.B. Everett, Functional Neuroanatomy. Lea & Febiger 1971, with permission of Williams & Wilkins\). This is a posterior \(dorsal\) view of the caudal cervical cord enlargement \(at about C7 or C8\) and the upper thoracic cord. The dura has been reflected \(and the arachnoid removed\) to reveal the cord. Note that the posterior \(dorsal\) rootlets \(the root itself is hidden beneath the dura at the dorsal root ganglion\) form an almost continuous line of rootlets in the dorsolateral \(posterolateral\) sulcus. The dorsomedian \(posteromedian\) sulcus marks the division between left and right halves of the cord. The cuneate and gracile fasciculi can be seen on the surface; they are bundles of axons running longitudinally, that together make up the posterior funiculus \(white matter\).  The denticulate ligaments are extensions of pia that anchor the cord laterally to the dura. Although they develop at each segmental level, they may appear irregularly-placed in the adult."))
