General Information

Term

larval A1-7-innervating LT3 motor neuron

ID (Ontology)

FBbt:00110269 (Fly Anatomy)

Definition

Larval LT3 motor neuron that innervates only the lateral transverse muscle 3 in an A1-7 segment. It fasciculates with the SNa nerve branch, alongside other LT-innervating motor neurons, and innervates the LT3 muscle in the same segment as its soma with type Ib boutons (Landgraf et al., 1997; Wang et al., 2022).[ FlyBase:FBrf0099344 FlyBase:FBrf0253566 ]

Also Known As

"A1-7 MN-LT3" ; "A1-7 MN23-Ib"
