Extraocular muscles tutorial

The video tutorial covers the anatomy and function of extraocular muscles, focusing on eye movements such as horizontal, vertical, and pivotal. It explains the roles of specific muscles like the superior rectus, inferior rectus, medial rectus, and lateral rectus, as well as the superior and inferior oblique muscles. The tutorial highlights the importance of understanding the axis of the eyeball and orbit, which are offset by 23 degrees, affecting muscle actions. It also introduces the concept of clinical testing for these muscles and the innervation pattern LR6SO4R3.
