General Information
Term mouth hook ID (Ontology) FBbt:00001846 (Fly Anatomy)
Definition A moveable chitinous structures at the anterior tip of the cephalopharyngeal skeleton of the larva. There is a bilateral pair of these, with one on either side of the atrium. Each mouth hook has three processes: a hooked oral process extending anteriorly, a ventral process, and a dorsal process extending dorso-posteriorly to the median tooth. The mouth hooks develop from the maxillary segment.[ FlyBase:FBrf0007733 ]
