mesothoracic sternal posterior rotator muscle motor neuron [FBbt_00053570]

mesothoracic sternal posterior rotator muscle motor neuron

ID: FBbt_00053570

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

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