inversion

Examples of inversion in the following topics:

• Muscles that Cause Movement at the Ankle

  • Eversion (tilting of the sole of the foot away from the midline) and inversion (tilting of the sole of the foot inwards towards the midline) is controlled by the subtalar joint formed between the talus and calcaneus bones of the foot.
  • The ankle joint is held in place by numerous strong ligaments that can be easily damaged when excessive force is placed on the ankle, particularly during strenuous inversion and eversion.
  • Physiologically, there is a preference for the foot to invert, so these muscles also prevent excessive inversion.

• Proprioceptive Sensations

  • This reflex is also called the inverse myotatic reflex, because it is the inverse of the stretch reflex.

• Motor Units

  • Precision is inversely proportional to the size of the motor unit.

• Stability and Range of Motion at Synovial Joints

  • Certain joints exhibit special movements including elevation, depression, protraction, retraction, inversion, eversion, dorsiflexion, plantar flexion, supination, pronation, and opposition.

• Blocking of Hormone Receptors

  • In pharmacology, antagonists have affinity but no efficacy for their cognate receptors, and binding will disrupt the interaction and inhibit the function of an agonist or inverse agonist at receptors.

• Factors Affecting Pulmonary Ventilation: Airway Resistance

  • Resistance in an airway is inversely proportional to the radius of the airway.
  • Another important fact is that airway resistance is inversely related to lung volumes because the airways expand a bit as they inflate, so the airways in a fully inflated lung will have lower resistance than a lung after exhalation.

• Shin Splint Syndrome

  • Exercises should focus on strengthening the tibialis anterior and other muscles controlling both inversion and eversion of the foot .
  • Exercises for shin splints should focus on strengthening the tibialis anterior and other muscles controlling both inversion and eversion of the foot.

• Inspiration

  • Pressure and volume are inversely related to eachother, so the drop in pressure inside the lung increases the volume of air inside the lung by drawing outside air into the lung.

• Factors Affecting Pulmonary Ventilation: Compliance of the Lungs

  • Compliance is inversely related to the elastic recoil of the lungs, so thickening of lung tissue will decrease lung compliance.

• Absorption of Alcohol

  • This inverse association was consistent across strata of age, sex and body mass index.
