Master CN IX Glossopharyngeal X Vagus Clinical Bedside Guide to Lower Cranial Nerves

Cranial Nerve Examination: CN IX (Glossopharyngeal) & CN X (Vagus) | Step-by-Step Bedside Guide
Learn how to assess Cranial Nerves IX and X with this easy-to-follow bedside guide. Perfect for medical students, residents, and clinicians!
In this session, we cover:
🔹 CN IX – Glossopharyngeal Nerve: Taste from the posterior one-third of the tongue, gag reflex, swallowing
🔹 CN X – Vagus Nerve: Palate elevation, phonation, swallowing, and autonomic functions
🔹 Clinical Focus: How to identify dysphagia, voice changes, and brainstem or lower cranial nerve lesions
By the end of this video, you’ll be able to:
• Identify the key functions of CN IX and CN X
• Perform a bedside neurological examination
• Recognize common clinical signs of lower cranial nerve dysfunction
• Apply your findings for accurate neurological localization
