Inner Ear Anatomy Diagram - Semicircular Canals, Cochlea, and Vestibular System #17600 (License: Personal Use)

This vintage-style black-and-white anatomical drawing depicts the bony labyrinth of the human inner ear, with numbered labels identifying key structures: the semicircular canals (1) responsible for detecting rotational movement, the spiral-shaped cochlea (2) essential for hearing, and the vestibule (3) involved in balance perception. Fine cross-hatching and precise linework emphasize spatial relationships and structural depth, typical of 19th- to early 20th-century medical illustrations.

Used in medical textbooks, otology resources, and educational websites to teach vestibular and auditory system anatomy; matches user intent for studying or reviewing inner ear physiology and pathology.
