Equilibrium

Examples of Equilibrium in the following topics:

• Vestibulocochlear (VIII) Nerve

  • The vestibulocochlear nerve (auditory vestibular nerve) is the eighth of twelve cranial nerves and has axons that carry the modalities of hearing and equilibrium.
  • The vestibulocochlear nerve has axons that carry the modalities of hearing and equilibrium.
  • Damage to the vestibulocochlear nerve may cause hearing loss, vertigo, false sense of motion, loss of equilibrium in dark places, nystagmus, motion sickness, and gaze-evoked tinnitus.

• Henry's Law

  • If a glass of the drink is left in the open, the concentration of carbon dioxide in solution will come into equilibrium with the carbon dioxide in the air, and the drink will go flat.
  • Henry's law states that at a constant temperature, the amount of a gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.
  • The practical description for the law is that the solubility (i.e., equilibrium) of a gas in a liquid is directly proportional to the partial pressure of that gas.
  • Henry's law also applies to the solubility of other substances that aren't gaseous, such as the equilibrium of organic pollutants in water being based on the relative concentration of that pollutant in the media its suspended in.
  • The solubility captures the tendency of a substance to go towards equilibrium in a solution, which explains why gasses that have the same partial pressure may have different tendencies to dissolve.

• Movement of Fluid Among Compartments

  • The water passes from a high concentration (of water) outside of the vessels to a low concentration inside of the vessels, in an attempt to reach an equilibrium.
  • Because the blood in the capillaries is constantly flowing, equilibrium is never reached.

• Pons

  • The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that regulate sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.
  • The functions of the four nerves of the pons include sensory roles in hearing, equilibrium, taste, and facial sensations such as touch and pain.

• Aging and the Skeleton

  • Equilibrium therapies may be included.

• Steps of Tissue Repair

  • The skin consists of the dermis and epidermis that exist in equilibrium.

• Overview of Sensation

  • Sense orqans (made up of sensory receptors and other cells) operate the senses of vision, hearing, equilibrium, smell, and taste.
  • Balance or equilibrioception: Allows the sensing of body movement, direction, and acceleration, and to attain and maintain postural equilibrium and balance.

• Penis

  • More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium.

• External Respiration

  • Equilibrium between the alveolar air and capillaries is reached quickly, within the first third of the length of the capillary within a third of a second.
  • Equilibrium between the alveolar air and the capillaries for carbon dioxide is reached within the first half of the length of the capillaries within half a second.

• Osteoporosis

  • Fall-prevention advice includes exercise to tone deambulatory muscles; proprioception-improvement exercises; and equilibrium therapies may be included.
