| Term |
mesothoracic tergotrochanter muscle motor neuron |
ID (Ontology) |
FBbt:00007406 (Fly Anatomy) |
| Definition |
Motor neuron that innervates the mesothoracic extracoxal trochanter depressor muscle 66 (tergotrochanteral muscle), ipsilaterally (Baird et al., 1993; Ehrhardt et al., 2023). Its large cell body is located laterally in the posterior ventral accessory mesothoracic neuromere (Baird et al., 1993; Phelan et al., 1996). Within the ventral nerve cord, it forms two main branches, one that extends medially, then anteromedially, reaching the midline and another that extends posteriorly (Baird et al., 1993). It is electrically synapsed to the giant fiber neuron, which it contacts via its medial branch, and it functions in jump response escape behavior (Baird et al., 1993; Phelan et al., 1996). Its axon exits the ventral nerve cord via the posterior dorsal mesothoracic nerve (Baird et al., 1993). In the male, it plays a role in pulse song generation (O'Sullivan et al., 2018).[ FlyBase:FBrf0058907 FlyBase:FBrf0085744 FlyBase:FBrf0240039 ] |
