Equilibrium Anatomy

Several types of sensory receptors provide information to the brain for the maintenance of equilibrium. 42 anatomy of the ear and physiology of hearing and equilibrium.

Ch 15 Inner Ear Static Dynamic Equilibrium A P2 Exam 1

Static equilibrium when a system reaches a point of stability in which no parts are still moving.

Equilibrium anatomy. The vestibular system equilibrium along with audition the inner ear is responsible for encoding information about equilibrium the sense of balance. The condition of being evenly balanced. A sensory receptor called a macula is located in the walls of the saccule and utricle the two bulblike sacs of the vestibule.

A macula contains numerous receptor cells called hair cells from which numerous stereocilia long microvilli and a single kinocilium a true cilium extend into a glycoprotein gel the otolithic membrane. Equilibrium a point in a reaction in which the lowest free energy exists on both sides of a chemical equation. A similar mechanoreceptora hair cell with stereociliasenses head position head movement and whether our bodies are in motion.

Along with hearing the inner ear is responsible for encoding information about equilibrium the sense of balance which it does in the vestibule and semicircular canals structures that are sometimes collectively referred to as the vestibular apparatus fig. A state of repose between two or more antagonistic forces that exactly counteract each other. In chemistry a state of apparent repose created by two reactions proceeding in opposite directions at equal speed.
