Dynamic Equilibrium Anatomy

The information for static equilibrium and linear acceleration dynamic comes from the utricle and saccule within the vestibule. A closer look however reveals that equilibrium is actually.

Dynamic equilibrium maintenance of the body posture mainly the head in response to sudden movements.

Dynamic equilibrium anatomy. Dynamic equilibrium is the steady state of a reversible reaction where the rate of the forward reaction is the same as the reaction rate in the backward direction. Static equilibrium also known as mechanical equilibrium means the reaction has stopped. Equilibrium balance static equilibrium maintenance of body posture relative to gravity while the body is still.

Equilibrium occurs when a reversible reaction a reaction that proceeds in both directions has an unchanging ratio of products and reactants. Dynamic equilibrium maintains the position of the head in response to rotational motion of the body such as rocking as in a boat or turning. Motion in the following two structures is detected as follows.

The functional components of the membranous labyrinth involved in the sensations of static and dynamic equilibrium are a system of thin walled intercommunicating tubes and ducts situated within the petrous part of the temporal bone at the base of the skull. The perception of equilibrium occurs in the vestibular apparatus. The saccule and utricle each contain a sense organ called the macula where stereocilia and their supporting cells are found.

There are five vestibular structures each containing a specialized mechanoreceptor a maculae within the utricle and saccule and a cristae within the ampullae of the superior horizontal and posterior semicircular canals. Static equilibrium inside the vestibule are two chambers. Dynamic equilibrium is different from a static equilibrium in which the parts do not move once theyve reached equilibrium.

Tracking a moving object. Sensory receptors for dynamic equilibrium are found in the cri when your body experiences acceleration or rotation the cupul hair cells respond to the motion of the cupula creating actio the nerve impulse travels down the vestibular nerve crosses o. Fluctuations occur within such systems in relation to seasons life cycles nutrient cycles energy cycles successional stages etc all within an apparently stable system.

In other words the system is at rest. The vestibule is the primary detector of changes in static equilibrium. The apparently steady but actually fluctuating state which is exhibited by stable ecosystems and communities.

The big picture of chemical equilibrium is static as the concentration of products and reactants is constant. Dynamic equilibrium has different meanings in each science sub discipline such as biochemistry or ecology.
