General Information
Term larval dorsal sensory cluster ID (Ontology) FBbt:00007296 (Fly Anatomy)
Definition Cluster of sense organs, and the somas and dendrites of sensory neurons, located dorsally, close to the surface of a larval segment (Campos-Ortega and Hartenstein, 1997). It lies above the dorsal insertion of the lateral transverse muscles, outside the dorsal intersegmental muscles (Campos-Ortega and Hartenstein, 1997). The pattern of sense organs and neurons is highly similar in segments A1-7, and slightly modified in the thoracic segments (Campos-Ortega and Hartenstein, 1997). The axons of neurons in this cluster fasciculate with the intersegmental nerve (Campos-Ortega and Hartenstein, 1997).[ FlyBase:FBrf0089570 ]
Also Known As "dorsal group of sensory organs" ; "embryonic/larval thoracic/abdominal dorsal sensory cluster" ; "larval thoracic/abdominal dorsal sensory cluster"
Comment Terminal (A8-10) segments have substantially different morphology, such that no 'dorsal cluster' is present as seen in more anterior segments.
