part of overlaps innervates larval central nervous system larval brain embryonic/larval cervical connective ccn Longitudinal connective of the embryonic/larval nervous system that forms the anterior continuation of several tracts of the ventral nerve cord into the brain after they anastomose in the subesophageal ganglion (Nassif et al., 1998; Hartenstein et al., 2015). It is composed of three tracts; the lateral, posterior and medial cervical tracts (Nassif et al., 1998; Hartenstein et al., 2015). Dorsally, after passing the foregut, it branches into the supraesophageal commissure and protocerebral connective (Nassif et al., 1998). The antennal nerve and the frontal connective branch off the cervical connective in the deutocerebrum (Nassif et al., 1998).
