RPAs EXPLAINED [Part 2a] | Vestibulospinal Reflex (VSR) & Vestibulocollic Reflex (VCR)

The video tutorial discusses the hip and stepping strategies, focusing on the vestibulospinal reflex (VSR) and vestibular colic reflex (VCR). It explains the anatomy of the vestibular apparatus, including semicircular canals and otolithic organs, and their role in sensing head position and movement. The pathways of the vestibular nerve and its fusion with the cochlear nerve to form cranial nerve 8 are covered. The structure and function of the vestibular nuclei and the medial and lateral vestibular tracts are detailed, highlighting their roles in controlling neck, arm, and leg muscles. The tutorial concludes with the importance of VSR and VCR in maintaining balance during large perturbations.

What is the significance of the cranial nerve 8 in the vestibular system?

How do the vestibulospinal and vestibular colic reflexes work together?

What happens when the ankle strategy is insufficient for maintaining balance?
