Ductions are monocular eye movements. Movement of the eye nasally is adduction; temporal movement is abduction. Elevation and depression of the eye are termed sursumduction (supraduction)...

2) Y axis: The medial force pulls the top of the eye towards the nose, rotating around the Y axis, causing intorsion (primary function). 3) Z axis: The medial force also pulls the back of the eye towards the nose, rotating the front of the eye around the Z axis, causing ABduction (tertiary function).
30 de oct. de 2023 · In the neutral position, the lateral rectus muscle is responsible for abduction. This muscle inserts on the anterior, lateral surface of the eye. The origin is the Annulus of Zinn.

Extraocular muscles. 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.
22 de dic. de 2022 · The levator palpebrae superioris (LPS) is the only muscle involved in raising the superior eyelid. A small portion of this muscle contains a collection of smooth muscle fibres – known as the superior tarsal muscle. In contrast to the LPS, the superior tarsal muscle is innervated by the sympathetic nervous system.

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.
By pulling the horizontal (lateral and medial) recti while holding longitudinal axis, students were shown the mechanism of eye abduction (A) and adduction (B), which is usually easy for students to understand.
