Nematode Anatomy Diagram - Internal Structure and Organ Labels #144268 (License: Personal Use)

This black-and-white line drawing depicts a longitudinal section of a typical nematode, illustrating its tubular body plan with distinct regions: anterior pharynx (P), nerve ring (N), dorsal/ventral nerve cords (D, O), excretory pore (En), and paired reproductive structures (M, H, E). Muscle bands (A, CI) and cuticle layers (C, DO) are clearly demarcated, supporting functional understanding of locomotion and osmoregulation. The diagram is commonly used in parasitology and invertebrate zoology curricula.

Used in educational textbooks, online biology courses, and scientific publications to teach nematode morphology; serves users seeking visual reference for lab identification, exam prep, or research context on roundworm anatomy.
