The extraocular muscles, or extrinsic ocular muscles, are the seven extrinsic muscles of the eye in humans and other animals. [1] Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye. The other muscle, the levator palpebrae superioris, controls eyelid elevation.

2024年10月15日 · Both of your eyes have six muscles that control movement. These muscles are how you can direct your eyes side-to-side, up and down or at diagonal angles. The muscles that control eye movement all attach to the outside of your eyeball, which is why experts sometimes refer to them as “external” or “extrinsic” muscles.

2021年3月1日 · There are two types of eye muscles: extrinsic muscles that control eye movement and position, and intrinsic muscles that control near focusing and how much light enters the eye. Extrinsic eye muscles (also called extraocular muscles) are attached to the outside of the eyeball and enable the eyes to move in all directions of sight.

2022年12月22日 · The extraocular muscles are located within the orbit, but are extrinsic and separate from the eyeball itself. They act to control the movements of the eyeball and the superior eyelid . There are seven extraocular muscles – the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and ...

Extraocular muscles are the most specialized skeletal muscles in the human body. These are broadly divided into voluntary and involuntary muscles. The voluntary muscles include seven extraocular muscles that control the movements of the eye and eyelids, and are important for binocular single vision.

2023年11月1日 · What is a Muscles Of Eye? The human eye is a complex organ responsible for vision, consisting of various muscles that facilitate its movement and function. These muscles play a crucial role in controlling the movement of the eye, allowing us to focus on objects, perceive depth and distance, and track moving targets.

2019年10月18日 · The human eye has six eye muscles. They are split into two primary groups: the recti muscles and the oblique muscles.

2023年8月7日 · Muscles directly associated with the eye include the extraocular muscles which control the external movement of the eye; the intraocular muscles, which are responsible for pupil accommodation and reaction to light; and the protractor and retractors of the eyelids.

2016年3月28日 · There are six eye muscles that control eye movement. One muscle moves the eye to the right, and one muscle moves the eye to the left. The other four muscles move the eye up, down, and at an angle. Read an overview of general eye anatomy to learn how the parts of the eye work together.

2025年3月22日 · 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.
