Which of the following is involved in static equilibrium?
Terms in this set (13) The central cavity of the bony labyrinth of the ear containing the functional components of the membranous labyrinth involved in the sensations of static equilibrium which are two vestibular structures, each containing a specialized mechanoreceptor, a maculae, within the utricle and saccule.
What is the process of static equilibrium?
static equilibrium – The special sense which interprets the position of the head permitting the CNS to maintain stability and posture when the head and body are not moving; it is detected by mechanoreceptors in the vestibule of the inner ear, the utricle and saccule, which each contain a macula with the receptors for …
What are the equilibrium receptors?
Receptors for two sensory modalities (hearing and equilibrium) are housed in the ear. The semicircular canals, the utricle, and the saccule of the inner ear are involved with equilibrium. Both hearing and equilibrium rely on a very specialized type of receptor called a hair cell.
What is the difference between static and dynamic equilibrium?
Static equilibrium is a state where bodies are at rest; dynamic equilibrium is a state where bodies are moving at a constant velocity (rectilinear motion). In both cases the sum of the forces acting on them is zero.
Is equilibrium a dynamic?
Dynamic equilibrium only occurs in reversible reactions, and it’s when the rate of the forward reaction is equal to the rate of the reverse reaction. These equations are dynamic because the forward and reverse reactions are still occurring, but the two rates are equal and unchanging, so they’re also at equilibrium.
What do static and dynamic equilibrium have in common?
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. In other words, the system is at rest.
Is photosynthesis static equilibrium?
NOTE: Photosynthesis is another example of a non-equilibrium system which can also be used as an example if studied in depth.
Why is photosynthesis a non equilibrium system?
Photosynthesis is a non-equilibrium system because it occurs in an open system within plant cells. Products generated from one part of the process can be transported to another part of the cell.
Is the system at equilibrium?
A system is at equilibrium when the rates of the forward and reverse reactions are equal. If additional reactant is added the rate of the forward reaction increases. As the rate of the reverse reaction is initially unchanged, the equilibrium appears to shift toward the product, or right, side of the equation.
What is normal equilibrium?
1 : a state of balance between opposing forces or actions. 2 : the normal balanced state of the body that is maintained by the inner ear and that keeps a person or animal from falling. equilibrium.
What is the opposite of equilibrium?
Antonyms for equilibrium agitation, imbalance, unevenness, excitement.
What is the increase sign?
Upwards pointing arrows are often used to indicate an increase in a numerical value, and downwards pointing arrows indicate a decrease.
