metathoracic sternal posterior rotator muscle motor neuron

ID: FBbt_00053571

Adult motor neuron that has its soma in the metathoracic neuromere and innervates the metathoracic sternal anterior rotator muscle (Azevedo et al., 2024; Cheong et al., 2025). There are four of these on each side and they fasciculate with the metathoracic leg nerve (Bates et al., 2025). (Azevedo et al., 2024)

Segmental homologue of similarly-named prothoracic neuron, but unclear from references which muscle from Miller (1950) - FBrf0186027 this innervates.
