Rectus medialis oculi muscle: Anatomy and functions
The rectus medialis oculi, also known as the rectus medialis oculi, is one of six muscles that control eye movement. It is located in the medial part of the orbit and plays an important role in ensuring accurate and coordinated eye movements.
The anatomical features of the rectus medialis oculi muscle include its origin from the anterior part of the orbital fissure and the inner surface of the orbit. From there it moves forward and attaches to the sclera of the eye, just in front of the cornea. This muscle controls the movement of the eye toward the nose, pulling the eye inward.
The functional aspects of the rectus medialis oculi muscle consist in the implementation of medial direct eye movement. When we look at close objects or turn our eyes inward while focusing, the rectus medialis muscle is activated. This allows us to focus our gaze on an object and maintain binocular vision.
In addition, the rectus medialis oculi muscle cooperates with other eye muscles to ensure smooth and coordinated movement of the eyeballs. This is necessary for following a moving object with the eyes or for moving the gaze from one object to another.
Dysfunction of the rectus medialis oculi muscle can occur in some medical conditions. For example, strabismus, or squint, can be caused by improper coordination of the eye muscles. If the rectus medialis eye muscle is too weak or too strong compared to other muscles, it can lead to abnormal eye position and strabismus.
Treatment for rectus medialis eye muscle dysfunction may include wearing special glasses or contacts, eye exercises, and sometimes surgery to correct the position of the eyes.
In conclusion, the rectus medialis oculi muscle plays an important role in controlling eye movement and maintaining binocular vision. Its anatomy and function are closely related to the other muscles of the eye, allowing precise and coordinated movement of the eyeballs. Understanding the role of this muscle helps us better understand how the eyes work and possible problems associated with eye movement.
Muscle of the eye rectus medialis. Muscle of the Eye. *** The muscles of the eye are organs of the auxiliary apparatus of the eye, which are muscle tissue combined with connective tissue***. The muscles of the eye control a number of physiological processes associated with the activity of the eyeball. Many of these muscles are innervated by the same nerve, due to which these muscles act in pairs according to the principle: when one relaxes, the other contracts. This is the general concept of the muscles of the eye.
***Myopic muscle*** **(pararugine)** is the outermost circular muscle, forming a triangle, the apex of which is projected at the inner corner of the palpebral fissure, the lower corners of which are directed anteriorly and to the sides. The lower edge of the pararugine muscle forms the lower eyelids, and in the upper part its remainder passes into the tendon of the muscle surrounding the eye. When contracting, the eye turns inward and upward in a circular manner.
**The periorbital muscle **consists of an inner and outer layer*.**
*The outer leaf**retracts the eye socket,** forming a lacrimal lake and the upper part of the eyelid. The inner leaf pulls the septum and upper eyelids forward.**
The striated ***four-eye muscle, **filling the orbital bursa,*** strengthens the ligamentous apparatus of the eye.*.*
In turn, the muscular aponeurotic arch (clinonephritis) divides the superficial aponeurosis into two halves: upper and lower.* The upper one takes more part in the formation of the upper eyelids, the upper part of which is formed by the outer part of its upper layer. ***Superior vein; and the septal superior*** veins secrete two packets connecting the internal oblique and transverse oblique muscles, the eye muscles and the deep anterior muscles of the eye at the site of their connections.* All these sections take part in the formation of the orbital floor.* At the level of the orbit, the interweaving of short fibers ascends in the shape of a funnel to the anterior surface of the upper edge of the orbit, approaching the nerve fibers passing here. * Due to this, the fibers of the muscle aponeurotic cells, as well as the fibrous fibers that make up the septa, intertwine, increasing the resistance to displacement of the internal oblique and rectus muscles. * The fibers of the oculomotor muscles intersect and divide, which may be a consequence of knot formation. The external rectus muscle complements the work of the external oblique muscle** in forming the lower eyelid.*** Its posterior fibers are attached to the eyeball and form the floor of the eye orbit.* The sixth nerve completely affects this muscle and, when contracted, raises the eyeball and deflects it outward.* The anterior rectus capitis muscle works in conjunction with the external rectus muscle
