A Practical Guide to Clinical Medicine In the setting of an eye movement problem, isolating which muscle or CN is the culprit can be tricky. 1  When trying to isolate a problem, it can help to check movement in the direction in which that muscle is the primary mover. This can be assessed as follows: 2  Superior oblique: Depresses the eye when looking medially.

Laser iridotomy Definition of Acute angle-closure glaucoma. Acute angle-closure glaucoma: Increased pressure in the front chamber (anterior chamber) of the eye due to sudden (acute) blockage of the normal circulation of fluid within the eye. The block takes place at the angle of the anterior chamber- the space at the junction of the cornea with the iris.

Superior oblique muscle Function[edit] The primary (main) action of the superior oblique muscle is intorsion (internal rotation), the secondary action is depression (primarily in the adducted position) and the tertiary action is abduction (lateral rotation).

Superior oblique muscle (May 2015) (Learn how and when to remove this template message) The superior oblique muscle, or obliquus oculi superior, is a fusiform muscle originating in the upper, medial side of the orbit (i.e. from beside the nose) which abducts, depresses and internally rotates the eye. It is the only extraocular muscle innervated by the trochlear nerve (the fourth cranial nerve).

- Together with the abducens nerve, the sixth cranial nerve, the trochlear nerve helps the eye move in a lateral (toward the midline) direction. The trochlear nerve controls the superior oblique muscle, which is one of the six extraocular muscles that influence eye movement.n other words, using the superior oblique muscles will cause the eyes to become crossed.. If the trochlear nerve is harmed, a condition called trochlear nerve palsy (or fourth nerve palsy) may result.

Difference between Perspective, Isometric, Oblique and Orthographic Drawing Oblique: Oblique projection is a method of drawing objects in 3 dimensions. It is a type of drawing involving a combination of a flat, orthographic front with depth lines rece ding at a selected angle, usually at 45 degrees. Isometr ic: Isometric drawing is way of presenting designs/drawings in three dimensions.

iris Plural irises or irides (ī'rĭ-dēz', ĭr'ĭ-) The colored, muscular ring around the pupil of the eye in vertebrate animals, located between the cornea and lens. Contraction and expansion of the iris controls the size of the pupil, thereby regulating the amount of light reaching the retina.

- A common eye muscle condition in which both eyes do not easily turn inward to see close objects and at near distances. In other words, the eyes do poorly (insufficiency) with the inward turning action (convergence) required for successful close viewing (such as, at reading or computer distance). This visual condition is the leading cause of eyestrain, blurry vision, double vision (diplopia), and/or headaches.

Human Physiology/Print Version Five of the extraocular muscles have their origin in the back of the orbit in a fibrous ring called the annulus of Zinn: the four rectus muscles and the superior oblique muscle. The four rectus muscles attach directly to the front half of the eye (anterior to the eye's equator), and are named after their straight paths.

What is the Pupil of the Eye? - Definition & Function The pupil of the eye is the black circle in the center of the iris. The iris is the colored ring in the eye with a color and structure unique to each person. From the outside of the eye, light passes through the clear lens, then through the pupil.

Eye Movements The field of action of an extraocular muscle is the direction of rotation of the eye when that muscle contracts. This term also indicates the gaze position in which the effects of a muscle most easily are demonstrated.ertical rectus muscles. Superior and inferior rectus muscles are the primary vertical movers of the eye. The superior rectus acts as the primary elevator, and the inferior rectus acts as the primary depressor of the eye. This vertical action is greatest with the eye in the abducted position.

Vergence Eye convergence. In ophthalmology, convergence is the simultaneous inward movement of both eyes toward each other, usually in an effort to maintain single binocular vision when viewing an object. This action is mediated by the medial rectus muscle, which is innervated by Cranial nerve III. It is a type of vergence eye movement.

orthographic projection Two-dimensional isometric or oblique views of a three-dimensional object on a drawing surface at right angles to the views and the lines of sight (projection). In these views the lines of the object parallel to the drawing surface are of true length and thus can be drawn to scale.

Abdominal external oblique muscle From Wikipedia, the free encyclopedia. The external oblique muscle (of the abdomen) (also external abdominal oblique muscle) is the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen.he external oblique is situated on the lateral and anterior parts of the abdomen. It is broad, thin, and irregularly quadrilateral, its muscular portion occupying the side, its aponeurosis the anterior wall of the abdomen.
