The human ear is an evolutionary derivative of the lateral line canals of early aquatic vertebrates such as fishes. Both the organs of hearing and equilibrium are based on an "internalized" system of fluid-containing membrane-bound spaces embedded in the petrous part of the temporal bone. ...

This article is all about the structure of the ear and how it functions to help maintain the balance and equilibrium of the body.
In vertebrates, including man, the organs of equilibrium are represented by the vestibular apparatus, whose receptor is located in the inner ear. Signals that are associated with body position or acceleration arise from the equilibrium receptors when there is mechanical stimulation of the sensory hairs...
Global balance of inner and middle ear pressure is controlled by the cerebrospinal fluid inside and the atmospheric pressure outside. The cochlear and vestibular aqueducts and the Eustachian tube, connected by a one-way communication, provide a fine control over inner and middle ear pressure.关键...

’, ‘Why is equilibrium important in biological systems”, “What is an example of equilibrium in biology?”, “What are the types of equilibrium, at least in biology?” Etymology The word “equilibrium” has its roots in Latin. It can be traced back to the two Latin words “aequus”...
2.In chemistry, a state of apparent repose created by two reactions proceeding in opposite directions at equal speed; in chemical equations, sometimes indicated by two opposing arrows (⇄) instead of the equal sign. See also:equilibrium constant. Synonym(s):dynamic equilibrium ...
Not only are the organs of equilibrium and hearing close together anatomically, lying side by side in the petrous bone to form the inner ear ; they are also derived from the same structure in evolution. Because in man the most important means of communication, speech, is mediated by the ...
