Fine structure of a sensory organ in the arista of Drosophila melanogaster and some other dipterans

  journal={Cell and Tissue Research},
SummaryThe arista, a characteristic appendage of dipteran antennae, consists of 2 short segments at the base and a long distal shaft. A small sensory ganglion, from which arises the aristal nerve, is located proximally in the shaft. The fine structure of the aristal sensory organ was studied in detail in the fruitfly (Drosophila) and for comparison in the housefly (Musca) and the blowfly (Calliphora). In Drosophila, the aristal sense organ consists of 3 identical sensilla that terminate in the… 

Drosophila Hook-Related Protein (Girdin) Is Essential for Sensory Dendrite Formation

It is shown that the Drosophila melanogaster single member of the Hook-related protein family, Girdin, is essential for sensory dendrite formation and function and defects in cilia are observed in other sensory organs such as those mediating olfaction and taste, suggesting that GirdIn has a general role in forming sensory dendedrites in Drosophile.

Light- and electron-microscopic analysis of the statocyst of the American crayfishOrconectes limosus (Crustacea, Decapoda)

The statocyst of Orconectes limosus contains static hairs arranged in four groups and two possible stimulus-mediating mechanisms are discussed: pressure changes in the receptor cavities and shearing of the base of the cilia with respect to the preciliary region.

Neuronal architecture of the antennal lobe in Drosophila melanogaster

Computer reconstruction of the antennal lobe of Drosophila melanogaster has revealed a total of 35 glomeruli, of which 30 are located in the periphery of the lobe and 5 in its center, and no obvious sexual dimorphism of the glomerular architecture was observed.

The organization of the chemosensory system in Drosophila melanogaster: a rewiew

This review surveys the organization of the olfactory and gustatory systems in the imago and in the larva of Drosophila melanogaster, both at the sensory and the central level. Olfactory epithelia of

Comprehensive classification of the auditory sensory projections in the brain of the fruit fly Drosophila melanogaster

A comprehensive projection map of the auditory receptor cells (Johnston's organ neurons: JONs) from the antennae to the primary auditory center of the Drosophila brain is established, suggesting that each JON group, and hence each zone of thePrimary auditory center, might sense different aspects of sensory signals.

Differentiation of the thermo-/hygrosensitive (no-pore) sensilla on the antenna of Antheraea pernyi (Lepidoptera, Saturniidae): a study of cryofixed material

SummaryThe morphogenesis of the thermo- and hygro-sensitive sensilla styloconica of Antheraea pernyi was studied, exclusively by cryomethods, during the second half of pupal development. The three

Antennal Morphology and Fine Structure of Flagellar Sensilla in Hippoboscid Flies with Special Reference to Lipoptena fortisetosa (Diptera: Hippoboscidae)

It is confirmed that these hippoboscids use chemoreception for host location, giving insights into this complex process in this poorly investigated group.

The structure of type-1 receptors is discussed with regard to the hypothesis for a mechano-electrical transduction, and the possible functions of lamellation and junctional connections in type-2 receptors are discussed.

Lamellated outer dendritic segments of a sensory cell within a poreless thermo- and hygroreceptive sensillum of the insect Carausius morosus

Electrophysiological recording yielded evidence that a cold, a dry and a moist air receptor are present in a sensillum field on the 12th segment of the antennae of Carausius morosus.

Lamellated outer dendritic segments of a chemoreceptor within wall-pore sensilla in the labial palp-pit organ of the butterfly, Pieris rapae L. (Insecta, Lepidoptera)

Electrophysiological recordings show that the sensory cells in the apical pit of the third segment of the labial palps in Pieris rapae are olfactory receptors, which react to a variety of complex plant odors and to the odor of conspecifics.

Sensory projection patterns of supernumerary legs and aristae in D. melanogaster

The data suggest that normal and supernumerary afferents compete with one another in a subtle way which is not accompanied by gross morphological changes of the projection patterns.

Projection patterns of different types of antennal sensilla in the antennal glomeruli of Drosophila melanogaster

SummaryCobalt fills from small, defined regions of the antenna in D. melanogaster show that the three types of sensilla on the third segment, the flagellum, and a fourth sensillum located in the

The sensillum capitulum, an antennal hygro- and thermoreceptive sensillum of the cockroach, Periplaneta americana L.

Structural features are discussed with regard to the mechanism of hygroreception in P. americana, a hygro- and thermoreceptive sensillum of the cockroach Periplaneta americana L.

Ultrastructure and ontogeny of the hair sensilla on the funicle of Calliphora erythrocephala (Insecta, Diptera)

Four envelope cells are responsible for the formation of the basiconical sensilla of Calliphora, and the tormogen cell degenerates, having produced about two-thirds of the sensilla cuticle after pupation.
