Extraocular muscles
Extraocular muscles
The Extraocular muscles (/ɛkstrəˈɒkjʊlər ˈmʌsəlz/; from Latin extra meaning "outside" and oculus meaning "eye") are a group of six muscles that control the movements of the eye. These muscles are responsible for the voluntary and involuntary movements of the eyes, allowing us to focus on objects at different distances and angles.
Structure
The extraocular muscles consist of four rectus muscles and two oblique muscles. The rectus muscles include the superior rectus, inferior rectus, lateral rectus, and medial rectus. The oblique muscles are the superior oblique and inferior oblique.
Function
The extraocular muscles work together to control the complex movements of the eyes. The superior rectus and inferior rectus control vertical movements, the lateral rectus and medial rectus control horizontal movements, and the superior oblique and inferior oblique control torsional movements.
Clinical significance
Disorders of the extraocular muscles can lead to conditions such as strabismus, where the eyes do not align properly, and nystagmus, which involves involuntary eye movement. Treatment for these conditions may involve surgery to correct the alignment of the muscles, or therapy to improve muscle control.
