General Information
Term larval transverse nerve ID (Ontology) FBbt:00001996 (Fly Anatomy)
Definition Nerve that exits the ventral nerve cord at the dorsal midline and bifurcates to form two lateral branches to the periphery (Gorczyca et al., 1994; Santos et al., 2006). These nerves are only found in abdominal segments (Gorczyca et al., 1994; Santos et al., 2006).[ FlyBase:FBrf0075005 FlyBase:FBrf0089570 FlyBase:FBrf0195119 ]
Also Known As "larval segment boundary nerve" ; "larval TN" ; "larval TVN"
Comment Santos et al. (2006) refer to the proximal region as the median nerve (MeN) and the post-branch point region as the transverse nerve.
