Source: Guan, W., et. al. Visualize Drosophila Leg Motor Neuron Axons Through the Adult Cuticle. J. Vis. Exp. (2018) This video demonstrates imaging of Drosophila legs with green fluorescent protein-expressing motor neurons using confocal microscopy. A laser and two detectors capture GFP and cuticle autofluorescence. Images are processed by splitting channels, subtracting autofluorescence, and merging into a colored composite image to visualize axons within the leg segment.

The limiting factor in the use of the adult Drosophila eye to study neurodegeneration and cell biology is the difficult imaging of intracellular processes. We describe the dissection of single ommatidia to generate a bona-fide primary neuronal cell culture, which can be subject to drug treatment and advanced imaging.

FAQs
The segmented leg provides a framework for examining appendage organization across distinct regions and joints. During Drosophila leg dissection, investigators can assess how muscles, sensory organs, and nerves are positioned relative to those segments. This makes the preparation useful for relating local anatomy to leg function and development.
Careful removal exposes internal structures while reducing the risk of disrupting the joints, muscles, sensory organs, or nerves being studied. Preserving these components maintains their anatomical relationships, which is essential when researchers interpret structural differences or examine how changes in one tissue may relate to movement or other leg functions.
Tissue labeling can make selected structures visible within the exposed preparation, allowing investigators to distinguish anatomical components and examine their organization. In this context, labeling supports direct analysis of muscles, sensory organs, or nerves and helps connect their cellular or structural appearance with developmental, functional, or locomotor findings.
The preparation begins by anesthetizing the fly and securing the specimen for manipulation. Researchers then work under a stereomicroscope with fine instruments, removing surrounding cuticle and tissue to expose the leg. The sequence is designed to produce a clear view while preserving the structures needed for anatomical, developmental, sensory, or neuromuscular analysis.
A stereomicroscope provides the magnified view needed to manipulate the small specimen, while fine instruments support controlled removal of cuticle and tissue. Anesthesia limits movement, and securing the fly stabilizes the preparation during handling. Together, these conditions improve access to the segmented leg and help protect delicate anatomical structures.
The exposed leg allows researchers to examine how segmented appendage structures are organized during development. Observations can focus on joints, muscles, sensory organs, and nerves, providing anatomical context for appendage patterning. This approach helps relate developmental changes at the tissue level to broader differences in leg organization and function.
By exposing and labeling specific leg tissues, the preparation provides a way to compare anatomy with genetic or molecular changes. Researchers can then consider whether altered muscles, nerves, sensory organs, or joints correspond to differences in movement. This links cellular structure and neuromuscular organization with observable locomotor phenotypes in biology studies.
