Q

What is “Reaction”

A
  • How the body responds to stress

Q

How Skin Protects (5)

A
  • First line of defence against pathogens
  • Melanin (UV Rays)
  • Keratin (durability)
  • Fatty/lipid Substance (prune-y skin for waterproofing)

Q

How Skin Thermoregulates

A

The dermis contains 8-10% of body’s blood

*Subcutaneous blood vessels dilate and constrict in response to temperature

Q

Derivation

A

Blood vessels expand (vasodilate), capillaries fill and . bring more blood to the surface of the body so heat can escape

Q

Retrostasis

A

Blood vessels narrow (vasoconstrict) which reduces blood flow at surface thereby conserving heat in the body

Q

How does the skin perform Absorption

A

Skin absorbs fat-soluble materials through capillaries in hair shafts therefore therapeutic additives can be added to water treatments

Q

Body’s Thermostat

A

Hypothalamus via feedback loop

*Skin temperature is most important signal it receives!

25
Core temperature vs Skin Temperature
``` Core = 37 degrees Skin = 33-35 degrees ```
26
Thermo Receptors of Body (3)
1) Pre-optic area of hypothalamus 2) Spinal cord, abdomen and other internal structures 3) Skin
27
How does the Pre-optic area of Hypothalamus regulate temperature
Heat sensitive neurons increase impulse output as temperature increases and decrease impulse output as temp decreases
28
How do the Spinal cord and Abdomen regulate temperature
Transmit signals, mostly cold, to central nervous system
29
How does the Skin regulate temperature
Contains receptors for hot AND cold Transmit nerve impulses to spinal cord to then be relayed to hypothalamus *4 to 10 times as many cold receptors as hot!
30
Properties of Water (9)
1) Exists in 3 states 2) Easily applied (bend to any shape) 3) Accessible 4) Universal Solvent (passes through tissues easily) 5) Hydrostatic Pressure 6) Buoyancy 7) Absorbs and Stores Heat (specific heat) 8) Thermal Conductivity 9) Mechanical and Chemical Effects (water jets; epsom)
31
What is Hydrostatic Pressure
- Pressure being exerted on a body submerged in water remains the same at a constant depth - Horizontal pressure remains equal at any depth * Pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above * Therefore density of the fluid affects the pressure too
32
What is Buoyancy
Density of the body is similar to that of water | *Salt makes sea water more dense = more buoyancy
33
What is Specific Heat
- Capacity of a substance to absorb (and give up) heat - Water is the standard of specific heat as it can absorb more heat for a given weight than any other substance - Water has a specific heat of 1
34
Significance of Specific Heat of Water
- 1 calorie (unit of heat) is required to raise 1 gram of water by 1 degree celcius - Takes a lot of heat to raise the temp of water which means it releases a lot of heat as it cools
35
What is Latent Heat
Amount of heat required to produce a change in state
36
Latent Heat of Vaporization
Energy required for liquid water --> vapour
37
Latent Heat of Fusion
Energy required for liquid water --> solid
38
What is Thermal Conductivity
- Capacity of a substance to transfer heat to other substances - Higher conductivity = better ability to transfer heat - Water readily transfers or removes heat when in contact * solids = 100x more than liquids; liquids 100x more than gases
39
What do Local Effects do (3)
*specific area/body part - increase or decrease blood flow - alternating local immune responses - increased pliability of the tissue Ex Paraffin Wax
40
How do Systemic Effects work
Whole body treatment | Ex jacuzzi - pressure exerted on body has a systemic effect beyond that of temperature alone
41
How do Reflex Effects work
Primary means by which temperature affects internal organs Ex stimulus on outside of body is picked up by central nervous system which enacts an internal response; cold on liver to "flush" it; warm on abdomen for diarrhea; cold on abdomen for constipation
42
Categories of Reflex Effects (3)
1) Vasomotor 2) Visceromotor 3) Glandular
43
Vasomotor Effect
Affects smooth muscle of blood vessels resulting in dilation or constriction
44
Visceromotor Effect
The effects on smooth muscle tissue of viscera caused by temperature change
45
Glandular Effect
Effects that temperature can cause on glandular secretions (mucus, hormones, enzymes)
46
Definition of Heat Transfer
An exchange of energy between two materials based on temperature difference between them
47
Types of Heat Transfer (5)
1) Conduction 2) Convection 3) Evaporation 4) Radiation 5) Conversion
48
Conduction
Direct contact needed (Ex hydrocollator pack)
49
Convection
Result of movement of heated liquid or gas between surfaces with different tempeartures
50
Radiation
Transfer of heat via infrared rays (contact not needed)
51
Conversion
- Heat not from an external source but from energy moving through a substance Ex Ultrasonic instrument
52
What is the Temperature Scale (7)
``` Cold Temperate Lukewarm Neutral/Indifferent Warm Hot Very Hot ```
