Thermosensation01:43

Thermosensation

33.1K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Decreased Body Temperature01:29

Decreased Body Temperature

829
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Body Temperature01:25

Body Temperature

3.7K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature

986
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

944
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

2.8K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Summary

This study reveals that altering body ownership perception influences physiological responses. Inducing a mirror-box illusion decreased hand temperature and thermal sensitivity, highlighting the interplay between body ownership and thermoregulation.

Area of Science:

  • Neuroscience
  • Psychology
  • Physiology

Background:

  • A coherent sense of body ownership is crucial for daily life and interaction.
  • The integration of exteroceptive, interoceptive, and proprioceptive signals is thought to be fundamental for body ownership.
  • Previous studies suggest a link between body ownership alterations and autonomic changes like thermoregulation, but evidence is conflicting.

Purpose of the Study:

  • To investigate the relationship between body ownership, thermoregulation, and thermal sensitivity.
  • To overcome limitations of previous experimental paradigms in studying body ownership.

Main Methods:

  • Utilized a novel application of the mirror-box illusion paradigm.
  • Measured changes in hand skin temperature and thermal sensitivity.

Main Results:

  • Induction of the mirror-box illusion led to a bilateral decrease in hand skin temperature.
  • Participants exhibited reduced thermal sensitivity to warm stimuli after the illusion was induced.
  • These results suggest a link between altered body ownership and physiological responses.

Conclusions:

  • The findings underscore the importance of integrating visual, autonomic, and proprioceptive signals for maintaining a coherent sense of body ownership.
  • This study provides new insights into the complex interplay between perception of the body and physiological regulation.
