Mollusk Auditory Organ Anatomy - Labeled Diagram & Explanation #17634 (License: Personal Use)

This vintage scientific illustration depicts the internal anatomy of a mollusk’s auditory organ, with labeled components including the otolith (d), auditory hair cells (c), outer connective tissue wall (b), and auditory nerve (a). The concentric layers and radial arrangement reflect the organ’s role in detecting sound vibrations and maintaining equilibrium. The diagram is based on Leydig’s original work, emphasizing histological detail typical of 19th-century comparative anatomy.

Used in educational biology resources, zoology textbooks, or museum exhibits to explain invertebrate sensory systems; targets students, educators, and researchers seeking foundational knowledge of molluscan physiology.
