The anatomy of a facial palsy (differentiating UMN vs LMN lesions)

This week let's tackle an area of anatomy that many learn ready for an exam, only to discover that this knowledge has gone again mere days to weeks later. The infamous but wonderful anatomy underpinning facial palsies and specifically how to differentiate upper vs lower motor neurone lesions.

In this podcast, we will discuss key anatomical principles underpinning types of motor neurones and give a nod to the corticobulbar tract. We will discuss how bicortical representation of the temporal branch of CNVII has no doubt saved countless lives. And finally, why weakness in the forehead and the inability to raise one’s eyebrows is somewhat reassuring in a facial nerve palsy. If this is an area of anatomy you struggle with or you simply want to hear more about it, then join us in this episode of dissectible me!
