(PHASERS)
Protection
Heat Regulation
Absorption

Excretion
Respiration
Sensation
What are the four main type within Protection?
Mechanical
Physical
Chemical
Mircobial
What do each of the four types in Protection mean…
Mechanical…
Physical….
Chemical….
Micriobal…
Mechanical… cuts or abrasions, its the physical barrier of the skin protects from and absorbs pressure
Physical…. heat rediation and sunlight radiation
Chemical…. drugs, skin products and pollution, this is the locked door helps keep out yucky chemicals
Micriobal…mircroorganisms such as germs and fungi, acidity surface ecology reduce chance for micriobal growth
Explain what Heat Regulation does?
sweat glands and blood vessels play a big role in keeping our bodies internal temp stable
98.6. Signal comes from the hypothalamus in our brain
tells our body to warm or cool our bodies
Explain Absorption…
our skin absorbs vitamin D
the most important substance we need
Some oils can be absorbed, these get through the hair follicle
Explain Secretion…
Sebum, the oil our needs to lubricant
sebaceous glands
this helps keeps our body moist
Explain Excretion..
this is sweat and toxins being removed from our bodies
sudoriferous glands our sweat glands
Explain Respiration…
small amounts of oxygen and other gases that enters and exits our skin
Secondary function
Explain Sensation….
sensory data
our skin gives our brain regarding outside stimulation
telling us if there is pain, cold, heat…
What are the three divisions of the skin?
Epidermis
Dermis
Hypodermis
How many layers are there in the Epidermis? Please name them… (GMGCHS)
6 layers
Germinative Layer or Stratum Germinativum
Malpighain Layer or Stratum Spinosum
Granular Layer or Stratum Granulosum
Clear Layer or Stratum Lucidum
Horny Layer or Stratum Corneum
Squamous Layer or Stratum Dysjunctum
What is the Epidermis?
the outer layer of your skin
Name the 1st layer of the Epidermis and explain what is does…
Germinative Layer or Stratum Germinativum
Juicy and living cells
Producing new cells and where mitosis happens
Vitamin D is mainly absorbed here
Name the 2nd layer of the Epidermis and explain what is does…
Melpighain Layer or Stratum Spinosum
‘spiny’ or ‘prickle’ cells
Cells start to dehydrate
Start to connect to each other
Name the 3rd layer of the Epidermis and explain what is does…
Granular Layer or Stratum Granulosum
Basel layer
Process of transformation
Cells are dry, waxy flakes
Keratin starts, waxy protien
**Creates the barrier function **
Name the 4th layer of the Epidermis and explain what is does…
Clear Layer or Stratum Corneum
Production of calluses
Filled with keratin
palms and feet
Name the 5th layer of the Epidermis and explain what is does…
Horny Layer or Stratum Corneum
Firmly cemented together (incellular cement)
Barrier to prevent TWEL
Where we bluebirds do our magic!
Name the 6th layer of the Epidermis and explain what is does…
Squamous Layer or Stratum Dysjunctum
scaly exterior cells waiting to be sloughed off body
What two layers are in the Dermis?
Papillary Layer
Recticular Layer
Explain the papillary layer…
loose (areolar) connective tissue
rich supply of blood capoillaries + nerve endings for touch
dermal papillae which project into the epidermis
Explain the reticular layer…
highly sensitive and made up of elastic material
collagen and elastic fibers
skins elasticity breaksdown from UV, smoking no sunscreen
large layer
Explain what the hypodermis is….
thick layer of irregularly connective tissue
fatty layer
below the dermis and on top of muscles
fat padding acts as a shock
absorber
