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. The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction. [2]

These six muscles are responsible for the movement of eyes into different gazes. The levator palpebrae superioris is responsible for eyelid elevation. The involuntary muscle group include superior tarsal muscle (Muller's muscle), inferior tarsal muscle and orbitalis.

To assess the six cardinal fields of gaze: use a penlight or some type of object a patient can track with their eyes. Position the penlight 12-14 inches from the patient’s face. Results: More nursing skills. Learn how to assess the six cardinal fields of gaze as a nurse.

There are six pairs of extraocular muscles responsible for rotating the eyes. Oftentimes they work together, obviating the need to coordinate both eyes independently. This section focuses on the anatomy, movements and innervations of the extraocular muscules.

2018年11月1日 · Learn about the function of these six muscles around each eye in today’s post. This extraocular muscle helps move the pupil away from the body’s midline. It’s also responsible for the horizontal movement, similar to the medial rectus muscle.

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.

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.

There are the six extraocular muscles, which act to turn or rotate an eye about its vertical, horizontal, and antero-posterior axes: inferior oblique (IO). Here is a schematic of a left eye, showing how its extraocular muscles insert into the eye:

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 …

The six extraocular muscles of the orbit involved in eye movements are the superior, inferior, medial and lateral rectus muscles, and the superior and inferior oblique muscles. The four rectus muscles arise from a thickening of the periosteum at the orbital apex known as the common tendinous ring (annulus of Zinn).
