General Information
Term ventral ellipse ID (Ontology) FBbt:00047237 (Fly Anatomy)
Definition Flattened annulus of fibers which lies in a frontal plane that crosses the midline at the posterior edge of the prothoracic medial ventral association center and extends axons posteriorly to the isthmus between the mesothoracic and metathoracic neuromeres (Power, 1948; Court et al., 2020). There is a lateroposterior extension of fibers from the posterior end of the ellipse into the metathoracic neuromere, into which joins the bundle that runs out into the metathoracic leg nerve (Power, 1948; Court et al., 2020). At the anterior end, the ventral ellipse incorporates the dorsal lateral tract of the ventral cervical fasciculus (Power, 1948; Court et al., 2020).[ FlyBase:FBrf0007196 FlyBase:FBrf0246815 ]
