Cranial Nerve Anatomy - The extra-oculor motor nerves (III, IV, VI) (part 1: anatomy)

Imaging in diplopia: what to double check in a patient with double vision! In this video, I discuss the anatomy of the extra-ocular motor nerves (oculomotor, trochlear, and abducens nerve) and illustrate their functions and anatomy, with clear correlations to how these structures impact eye movement and coordination. This video is part one of a two-part series, with the second part covering pathology. This video is aimed at medical students, radiology residents, and ophthalmology residents and will enhance your understanding of the imaging anatomy of these vital nerves. 0:00 - Introduction, what is diplopia. 3:56 - Topics 4:27 - Part 1: function 8:05 - Abducens palsy 8:47 - Trochlear palsy 9:43 - Oculomotor palsy 11:05 - Denervation patterns 13:37 - Part 2: Imaging Anatomy 13:46 - Extra-oculor motor nerve segments 15:11 - Brainstem segments 18:17 - Cisternal segments 22:39 - Dorello's canal (abducens nerve) 25:54 - Cavernous Sinus Anatomy 30:48 - Oculomotor cistern 32:05 - Extracranial segments #neuroradiology #neurology #ophthalmology #brainanatomy #diplopia #medicaleducation #medical #radiology #medicalstudent #cranialnerves #neuroanatomy
