(FRAME-INFO (STRING "Caudal Pons, Computer Reconstruction. This reconstruction highlights the origin of the abducens nerve \(VI\) from its nucleus, which lies just below the floor of the fourth ventricle. The abducens nuclei are motor nuclei \(general somatic efferent\) that control movement of the lateral rectus muscles; each nucleus innervates the ipsilateral muscle. The nerve rootlets pass ventrally through the tegmentum and emerge from the brainstem at the junction between the pons and the medulla just lateral to the pyramids. The sixth nerve then travels lateral to the dorsum sellae, passes through the cavernous sinus \(where it is sandwiched between the internal carotid artery and the trigeminal nerve\) and enters the orbit through the superior orbital fissure."))
