2023年10月30日 · Extraocular muscles are also referred to as the extrinsic (arising externally) or muscles of the orbit. There are 6 of these extraocular muscles that control eye movement (cows only have 4 of these), and one muscle that controls eyelid elevation.

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.

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.

2022年12月22日 · There are seven extraocular muscles – the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. Functionally, they can be divided into two groups: Responsible for eye movement – Recti and oblique muscles.

2019年10月18日 · “As with most of the muscles of the orbit, it is innervated by the inferior division of the oculomotor nerve (Cranial Nerve III). This muscle shares an origin with several other extrinsic eye muscles, the anulus tendineus, or common tendon. It is the largest of the extraocular muscles and its only action is adduction of the eyeball.” (Wikipedia)

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.

The extraocular muscles are the six muscles that control movement of the eye (Superior rectus, Inferior rectus, Lateral rectus, Medial rectus, Superior oblique and Inferior oblique) and one muscle that controls eyelid elevation (levator palpebrae).

2021年3月2日 · There are two types of eye muscles. Learn about the extrinsic muscles that control eye movement and intrinsic muscles that control near focusing.

2024年12月16日 · Six muscles outside the eye govern its movements. These muscles are the four rectus muscles —the inferior, medial, lateral, and superior recti—and the superior and inferior oblique muscles.

2020年5月10日 · These muscles are also known as the extrinsic eye muscles, distinguishing them from intrinsic eye muscles which are responsible for controlling the movement of the iris. This article will discuss the anatomy of the EOM including …
