Sensation
These are responsible for sensing hot and cold.
What are Thermoreceptors?
Heat regulation, also known as
What is thermoregulation?
When molecules are able to pass through the epidermis
What is transdermal penetration?
These two make up the skins permeability barrier
What is the Acid mantle and the stratum Corneum?
This gland is inactive until stimulated by hormones
What is the Apocrine gland?
These sense pain
What are pain receptors?
How the skin regulates temperature (heat)
What is sweating?
If the molecules of a product are small enough, permeation of chemicals may happen through this pathway
What is appendages of the skin ?
This is the first line of defense in the skin
What is the Acid Mantle?
Another term for excretion
What is detoxification?
Sensations of pressure, vibrations, movement and texture
What are Mechanoreceptors?
When blood vessels dilate to allow heat to evaporate
What is Vasodilation?
Lipid soluble products can use these in between corneocytes.
What are the intercellular spaces?
The conversion of living cells into dead protein cells
What is Keratinization?
The major sweat gland
Wat is the Eccrine gland?
These sense pressure and vibration and are located in the Stratum Basale layer
What are Merkel cells?
When the body is cold, blood vessels constrict or narrow to keep heat near essential organs
What is Vasoconstriction?
Molecules move directly through the corneocytes
What is transcellular diffusion?
Shedding, peeling or coming off in scales of the stratum corneum
What is Desquamation?
The difference between secretion and excretion (One removes something)
What is the removal of waste?
Sensing different parts of the body positioned in relation to each other and the environment
What are Proprioceptors?
When core body temperatures drop the body sends a signal for muscles to shake in small movements to expend energy
What is Thermogenesis?
The thicker this layer is, the slower the rate of penetration
What is the stratum corneum?
This is the last stage of the wound healing process
What is Maturation?
Excretion helps regulate temperature through excreting ______
What is sweat?
