adult metathoracic anterior intermediate commissure [FBbt_00047529]

adult metathoracic anterior intermediate commissure

ID: FBbt_00047529

Adult Nervous system Neuron projection bundle

Commissure of the anterior metathoracic neuromere that carries fibers from the intermediate tract of the dorsal fascicle and the haltere nerve to the contralateral side of the adult ventral nerve cord (Power, 1948; Court et al., 2020. After crossing the midline, fibers join the contralateral haltere nerve and proceed in their original (anterior or posterior) direction (Power, 1948. It is formed of fibers of hemilineages 7B, 8B and 18B and is the largest commissure of the ventral nerve cord (Court et al., 2020. It is derived from the larval metathoracic anterior intermediate commissure, which segregates into this and a ventral anterior intermediate commissure (Court et al., 2020. (Boerner and Duch, 2010, Court et al., 2020, Power, 1948)
