Presentation transcript:

Two Kinds of Equilibrium 1.Static equilibrium: Refers to the maintenance of body (head) position relative to the force of gravity. 2.Dynamic equilibrium: Refers to the maintenance of the body (head) in response to sudden movements such as rotation, acceleration, and deceleration

Gross Anatomy of the Vestibular apparatus

Components of the Vestibular Nerve

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

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

How the macula functions in relation to gravity

Dynamic Equilibrium The receptors for dynamic equilibrium are the semicircular canals

Anatomy of the Semicircular canal receptors called ampulla

How the Ampulla function to produce dynamic equilibrium sensations

Pathway for Vestibular System
