Body balance is not a simple mechanism; it is the result of coordinated interaction among three major physiological systems:
1️⃣ The Vestibular System located in the inner ear
2️⃣ The Visual System
3️⃣ The Proprioceptive System, which provides sensory input from muscles and joints regarding body position
The inner ear plays a central role in balance control. The utricle, saccule, and semicircular canals detect changes related to rotational movements, linear acceleration, and body orientation. These signals are transmitted to the brain via the vestibular nerve.
The brain integrates and processes this information, then sends appropriate commands to the muscles to maintain postural stability.
If any part of this pathway is disrupted, an individual may experience:
🔹 Dizziness
🔹 Imbalance
🔹 A floating or lightheaded sensation
🔹 Visual instability (Oscillopsia)
