Understanding Static and Dynamic Equilibrium in the Vestibular System

This lecture focuses on the two types of equilibrium essential for maintaining balance: static and dynamic equilibrium. Static equilibrium refers to the body's ability to maintain its position relative to gravity, involving receptors in the Utricle and Saccule. Dynamic equilibrium deals with responses to sudden movements, relying on the semicircular canals and the ampulla. This presentation also covers the anatomy of the vestibular apparatus, including the macula's role in static equilibrium and the pathways of the vestibular system.

  1. A&P Unit 4Lecture 6B

  2. Two Kinds of Equilibrium • Static equilibrium: Refers to the maintenance • of body (head) position relative to the force of • gravity. • Dynamic equilibrium: Refers to the maintenance • of the body (head) in response to sudden • movements such as rotation, acceleration, • and deceleration

  3. Gross Anatomy of the Vestibular apparatus

  4. Components of the Vestibular Nerve

  5. Static Equilibrium • The receptors for static equilibrium are the Utricle and the Saccule

  6. Location and structure of the receptors in the macula for static equilibrium

  7. How the macula functions in relation to gravity

  8. Dynamic Equilibrium • The receptors for dynamic equilibrium are the semicircular canals

  9. Anatomy of the Semicircular canal receptors called ampulla

  10. How the Ampulla function to produce dynamic equilibrium sensations

  11. Pathway for Vestibular System
