General Information
Term motor neuron of adult dorsal prothoracic nerve ID (Ontology) FBbt:00053100 (Fly Anatomy)
Definition Adult motor neuron that fasciculates with the dorsal prothoracic nerve (Azevedo et al., 2024). There are four of these on each side and they collectively innervate the prothoracic pleural and tergopleural promotor muscles (Azevedo et al., 2024). It has its soma in the anterior prothoracic neuromere (Azevedo et al., 2024).[ FlyBase:FBrf0259940 ]
Also Known As "MN 1-4"
Comment Unclear from Azevedo et al. (2024) whether neurons innervate one or both muscles.
