Fine structure of the dendritic junction body region of the antennal sensory cone in a larval elaterid (Coleoptera)

Abstract
The component ciliary collar, basal body, ciliary rootlets, trichogen–dendrite secretory junctions and secretory inclusions of the junction body region of dendrites in the wireworm antennal sensory cone are described. The primary function ascribed to the junction body region, based on the ultrastructural evidence presented, is one of secretion. The hypothesis that the secretory products produced in the junction body region are transported to the dendritic terminations in the sense organ is discussed and supported.
