Vestibulocular PCD involves which systems?

Digestive and respiratory Vestibular and ocular systems Endocrine and immune Musculoskeletal only

Correct Answer:

Vestibular and ocular systems

Explanation:

Vestibulocular PCD focuses on the connection between balance and eye movements. The vestibular system in the inner ear detects head motion, and the brain uses that input to drive eye movements so our gaze stays steady as we move. When a term like vestibulocular PCD is used, it highlights involvement or disruption in how the vestibular signals and ocular motor system coordinate. So these disorders are about the balance system and the eyes, and how they work together to stabilize vision. The other options point to systems that aren’t about this eye–balance coordination.
