| Term |
embryonic/larval frontal ganglion |
ID (Ontology) |
FBbt:00002629 (Fly Anatomy) |
| Definition |
A small paired ganglion of the embryonic and larval stomatogastric nervous system. At embryonic stage 17, it consists of approximately 25-30 neurons that form a U-shaped ganglion wedged between the anterior aspect of the brain hemispheres and the dorsal pharynx, and that have formed axons. The somata of the neurons surround a sparse neuropil domain and are enclosed in a glial sheath. Lateral projections from these neurons form the frontal connective. Medial projections that turn anteriorly on reaching the midline form the frontal nerve. Medial projections that turn posteriorly on reaching the midline form the recurrent nerve.[ FlyBase:FBrf0064803 FlyBase:FBrf0089570 ] |
| Also Known As |
"FNJ" ; "frontal nerve junction" ; "larval frontal ganglion" |
| Comment |
The term parapharyngeal ganglion was previously used to designate the frontal ganglion (Campos-Ortega and Hartenstein, 1997). |
