General Information
Term mechanosensory neuron of posterior dorsocentral bristle ID (Ontology) FBbt:00111221 (Fly Anatomy)
Definition Mechanosensory neuron that innervates the posterior dorsocentral bristle in the adult thorax. It fasciculates with the posterior dorsal mesothoracic nerve, extends ventrally and medially, bifurcates and follows the main course of the pathway anteriorly, extending halfway along the prothoracic neuromere, and posteriorly, up to the bifurcation of the metathoracic crossbranch. The main crossbranch extends contralaterally. Occasionally, anterior and posterior crossbranches are observed. The central branches form mostly terminal but also en passant synapses. Presynaptic terminals are enriched near the midline, along the anterior branch, contralateral branches and on four stereotypic locations on the posterior projecting branch.[ FlyBase:FBrf0034519 FlyBase:FBrf0227234 ]
