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

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

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

Anatomy of the Semicircular canal receptors called ampulla
