6 dni temu · Explore the anatomy and function of the eye muscles with Innerbody's interactive 3D model. Six skeletal muscles surround the eye and control the many diverse movements of the eyes. These muscles, although small and not particularly strong, are exceptionally fast and precise.
The anatomical origin is behind the eye on the lesser wing of the sphenoid bone, but the superior oblique muscle acts a pully, and loops back trough a connective tissue sling called the trochlea.
Each eye muscle is stimulated by a specific cranial nerve. The optic nerve (a cranial nerve), which carries impulses from the retina to the brain, as well as other cranial nerves, which transmit impulses to each eye muscle, travel through the orbit (the bony cavity that surrounds the eyeball).
