This video demonstrates the technique used for preparation of organizer and animal pole explants from Xenopus laevis embryos, including the use of the eyebrow knife - a specialized dissection tool made of one's eyebrow. The protocol for assembling an adhesion assay is also given, which probes for the presence of key adhesion molecules present on the surface organizer or animal pole cells that are critical for proper development.

This video describes how to dissect and isolate the adult Drosophila brain–a procedure necessary for visualizing the organ, which is otherwise obscured by the cuticle, eye, and tracheal tissue. The example protocol shows a detailed demonstration yielding high-quality preparations that can be used for immunostaining and imaging methods in Drosophila neurobiology.

Form and Function of Crickets and Crayfish ExpandNOTE: To observe the relationship between form and function in animals, you will be examining and dissecting a cricket and a crayfish. Each pair of students will receive one of each of these organisms. When dissecting, be sure to wear gloves, closed-toed shoes, and safety goggles. Take care when handling dissecting tools, as they may be sharp. HYPOTHESES: In this experiment, the experimental hypothesis could be that the cricket and crayfish have...
FAQs
Useful evidence depends on controlled separation rather than simply opening the specimen. The investigator preserves observable features while exposing organs, then traces how tissues are positioned relative to one another. This approach links visible organization with function and supports interpretations based on anatomical relationships, instead of isolated observations of individual structures.
Orientation establishes a consistent reference for locating structures before any tissue is disturbed. Controlled incisions then reveal progressively more anatomy while reducing the risk of losing relationships among organs and tissues. Using anatomical terminology to record these observations makes findings easier to communicate, compare across specimens, and connect with physiological roles.
Physical examination provides direct observation of exposed tissues and their spatial relationships. Models can support structural visualization, whereas imaging or digital alternatives can supplement study without requiring the same specimen handling. Combining these approaches lets instruction connect practical observation with other representations, while retaining dissection’s emphasis on tool use, terminology, and evidence-based interpretation.
Begin by orienting the specimen, then make controlled incisions to expose organs in a systematic order. Separate tissues carefully, preserve features that remain observable, and trace relationships among structures as they appear. Record interpretations using anatomical terminology and connect the observed arrangement with function. This sequence keeps the examination organized and supports later comparison.
They should examine more than the presence of individual organs. The important outcome is evidence about how tissues are arranged and how those relationships may support function. Comparing observations among structures, while preserving visible features, helps learners practice morphology and physiology together and develop explanations grounded in what the specimen actually shows.
It is particularly relevant when learners need to connect comparative anatomy, morphology, and physiology through direct structural observation. The method also develops anatomical vocabulary, careful tool handling, and evidence-based interpretation. Its value can be extended with models, imaging, or digital alternatives, allowing educators and researchers to match the approach to the learning or investigative context.
