Summary
An imbalance between the semicircular canals and otolith organs in the labyrinth causes motion sickness. This new theory explains major findings and integrates existing research on vestibular imbalance.
Area of Science:
- Neuroscience
- Vestibular System Physiology
Background:
- Current theories on motion sickness etiology have limitations.
- The labyrinth contains two major organs: semicircular canals and otolith organs.
Purpose of the Study:
- To present a new theory explaining motion sickness.
- To synthesize existing theories on motion sickness etiology.
Main Methods:
- Outlined strengths and limitations of current motion sickness theories.
- Described the roles of semicircular canals and otolith organs in motion sickness.
Main Results:
- The proposed theory explains numerous findings related to motion sickness.
- The theory integrates various current hypotheses on motion sickness.
Conclusions:
- Vestibular imbalance contributes to motion sickness.
- Differences in autonomic control between canals and otoliths may underlie motion sickness.

62.5K
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

6.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

1.3K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

01:22Equation of Motion: General Plane motion
592
In the context of a rigid body's movement within a general plane, it is important to understand that this motion is typically triggered by external forces or couple moments exerted onto it. This principle can be explained through Newton's second law, which stipulates the translational motion of the body's center of mass along each axis.
Moreover, the body's center of mass experiences a rotational effect as a result of these couple moments. This rotation can be articulated as the...

01:18Respiratory Regulation of Acid-Base Balance
1.8K
Respiratory compensation is a vital physiological process that stabilizes blood plasma pH by regulating the partial pressure of carbon dioxide (PCO2), a key determinant of pH levels. Most carbon dioxide in the blood dissolves and converts into carbonic acid (H2CO3). It dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3⁻). There is also an inverse relationship between PCO2 and pH.
When carbon dioxide levels increase in the blood, more H+ and HCO3⁻ are...

01:29Disorder of Water Balance
2.6K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...
