Ögondynor

Ögondynor, also known as the *lateral rectus muscle* in anatomical terminology, is a small skeletal muscle located in the human eye. It is one of the six extraocular muscles responsible for controlling eye movements. The ögondynor is specifically responsible for abduction, or the outward movement of the eye away from the midline of the body.

Anatomically, the ögondynor originates from the common tendinous ring (also called the annulus of Zinn) near the optic foramen in the orbit. It inserts into the lateral side of the eyeball, allowing it to rotate the eye laterally. This muscle works in conjunction with the medial rectus muscle to enable binocular vision, enabling both eyes to coordinate and focus on objects in the visual field.

In clinical practice, dysfunction of the ögondynor can lead to conditions such as lateral rectus palsy, where the affected eye fails to move outward properly. This can result in diplopia (double vision) and may require medical or surgical intervention. The muscle is innervated by the abducens nerve (cranial nerve VI), which controls its movement and function.

The ögondynor is essential for maintaining balance and coordination of gaze, particularly when shifting visual attention between objects in different directions. Its precise control is crucial for tasks such as reading, driving, and other activities requiring focused visual tracking.
