Neuroanatomy - Cranial Nerve III, The Oculomotor Nerve in 3D

Visit http://www.brainwashedsoftware.com for more information.

This is an animated demonstration of right cranial nerve III (oculomotor) nerve palsy, just one small piece of the cranial nerves module from Axiom Neuro, a new interactive functional atlas of neuroanatomy and neurology that features true 3D animation to bring users the most intuitive and easy-to-understand view of cranial nerve function available anywhere.

Other modules of the software include 13 spinal cord and brainstem nerve pathways and a virtual patient module that uses an animated neurology patient to demonstrate the common signs and symptoms of 10 neurological pathologies including strokes, diabetes and head trauma.

Maybe i don't understand the video. But the Oculomotor Nerve doesn't "controles" the

Superior oblique muscle ( it is innervated by the 4th cervical nerve), neither the Lateral Rectus (this is innervated by the 6th cervical nerve). Correct me if I am wrong. But I am 100% sure I'm right.

@TimTim725: You're right about CN III not controlling the superior oblique and the lateral rectus. However, this video only shows what happens when CN III in the left eye is damaged, CN IV and VI are still healthy in the patient.

The colored arrows in the eyeball model represent the different muscles and as you can see in this example, the superior oblique and lateral rectus are still functioning. Our software allows you to lesion each of the nerves one at a time to see the different effects.

@BrainwashedSoftware

actually it doesn't accurately display occulomotor (CNIII) palsy, the left eye would be permanently intorted and abducted if that were the case, due to the unantagonised actions of superior oblique and lateral rectus

[BrainwashedSoftware]

@fergie232 The patient presentation of a CN III palsy is as demonstrated in the video, with the patient's affected eye resting in a "down and out" position. Perhaps there's some confusion with the terms and the various muscle actions?

@BrainwashedSoftware I undestand now. Thank you. It's a nice software btw!

looks sweet.
