Nematode Anatomy Diagram - Key Structures and Functions #1270479 (License: Personal Use)

This black-and-white scientific illustration depicts a transverse section of a nematode, clearly labeling critical internal structures such as the dorsal and ventral nerve cords (N), hypodermis (SC), excretory canal (EC), pharynx (FB), and reproductive gonads (Y). The body wall musculature (M) surrounds the pseudocoelomic cavity, while the intestinal lumen (MN) runs longitudinally. The diagram serves as a foundational reference for understanding nematode morphology in parasitology and developmental biology.

Used in educational biology resources, textbooks, and online learning modules to teach invertebrate anatomy; supports user intent for academic study, research reference, or curriculum development on roundworm structure and function.
