General Information
Term adult maxillary nerve ID (Ontology) FBbt:00004043 (Fly Anatomy)
Definition Mixed sensory-motor nerve that innervates the adult gnathal ganglion (GNG) (Ito et al., 2014). It contains ~120 axons from the sensory cells of the maxillary appendages entering the maxillary neuromere of the GNG and GNG motor axons travelling to maxillary musculature (Nayak and Singh, 1985; Ito et al., 2014). The maxillary nerve is fused with the labial nerve for much of its length, forming the maxillary-labial nerve (Ito et al., 2014).[ FlyBase:FBrf0007735 FlyBase:FBrf0042883 FlyBase:FBrf0080339 FlyBase:FBrf0224194 ]
Also Known As"MXN" ; "MxN"
CommentMiller, (1950) considers the maxillary nerve to be a branch of the compound maxillary-labial nerve. More recent studies (e.g. Rajashekhar and Singh (1994), or Nayak and Singh (1985)) consider the maxillary nerve and labial nerve to be separate anastomosing nerves.
