larval metathoracic segmental nerve [FBbt_00002163]

Larval segmental nerve of the metathoracic segment. Similar to the A1-A7 nerves, it has two roots, anterior and posterior, both formed from neurons of the same segment as the nerve (Campos-Ortega and Hartenstein, 1997. Proximally it shares a glial sheath with the intersegmental nerve (Campos-Ortega and Hartenstein, 1997. It receives sensory fibers from the ventral monoscolopidial chordotonal organ, Keilin organ and vc1 sensillum (Campos-Ortega and Hartenstein, 1997. It gives off a thick branch to the ventral lateral muscle, while its main branch continues to the lateral transverse musculature, the ventral Kolbchen and the vc2 sensillum (Campos-Ortega and Hartenstein, 1997.
