Extrinsic Muscles of the Eye

This detailed pen-and-ink illustration showcases the six extrinsic muscles of the eye, responsible for coordinated ocular movement. Each muscle is meticulously rendered to highlight its origin, insertion, and function, with careful attention to anatomical accuracy and clarity.

The rectus muscles—superior, inferior, medial, and lateral—are depicted originating from the common tendinous ring and inserting onto the sclera, demonstrating their roles in directing the eye’s gaze. The oblique muscles, with their distinct paths, are illustrated to emphasize their unique mechanics: the superior oblique, passing through the trochlea to aid in intorsion and depression, and the inferior oblique, arising from the maxilla to assist in extorsion and elevation.

Fine line work and stippling techniques bring depth to the composition, distinguishing overlapping structures while maintaining a crisp, educational aesthetic. Cranial nerve innervation—oculomotor (CN III), trochlear (CN IV), and abducens (CN VI)—is also visually represented to reinforce neuroanatomical connections.

This illustration is designed as a reference for medical education, providing a clear and engaging depiction of ocular muscle function for students, clinicians, and educators.
