. In mammals it consists of the bony labyrinth a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts. The physiology of balance. The resting membrane potential is at equilibrium since it relies on the constant expenditure of energy for its maintenance.

Static gravitational equilibrium which involves the movement of the head with respect to gravity and dynamic rotational equilibrium which involves acceleration of the head in rotation horizontal and vertical movements. Sensory receptors located in the vestibule and in the membranous semicircular canals sense position and head movements to help maintain both static and dynamic equilibrium. However unique receptors within the inner ear play a crucial role in monitoring equilibrium.

There are two types of equilibrium. For quiescent cells the relatively-static membrane potential is known as the resting membrane potential. The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibriumThe information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes.

It is dominated by the ionic species in the system that has the greatest conductance across the membrane. Nerve fibers from these areas form the vestibular nerve which connects with the cochlear nerve to form the 8th cranial nerve. The cochlea dedicated to hearing.

The inner ear internal ear auris interna is the innermost part of the vertebrate earIn vertebrates the inner ear is mainly responsible for sound detection and balance.
