attached to prothoracic phragma adult transverse horizontal neck muscle tendon cell adult oblique horizontal neck muscle 1 2024-05-14T13:35:31Z Short dorsal neck muscle that attaches at the midline to the pronotal apodeme and extends anterolaterally (Gorko et al., 2024). It attaches via small tendon tendrils to the large tendon of the transverse horizontal muscles (Gorko et al., 2024). It is innervated by the VCvN and CvN2 motor neurons (Gorko et al., 2024). It is posterior to the other oblique horizontal muscles (Gorko et al., 2024). OH1 muscle FBbt:00053181 Based on dorsomedial attachment and proximity of lateral end to muscle 23 (TH muscles), OH1-3 probably correspond to muscle 20 in Miller (1950) - FBrf0186027. fly_anatomy.ontology dorsal cervical muscle 20
