What is the stomatogastric nervous system?
The stomatogastric nervous system is a neural network found in crustaceans that controls the movements of the stomach.
How is the STNS extracted?
The STNS is extracted through a two-part dissection process involving gross and fine dissection techniques.
What techniques are used in studying the STNS?
Techniques include electrophysiology, immunohistochemistry, and cell culture studies.
Why is the Jonah crab used for these studies?
The Jonah crab is a suitable model organism due to its well-defined nervous system and ease of dissection.
