4 main categories of receptors
Mechanoreceptors are responsible for:
Sensations of pressure, vibrations, movement and texture
What is thermoregulation also known as?
Heat regulation
Maintaining or improving a healthy skin barrier is also known as:
Permeability layer
Cell renewal begins at what layer in the epidermis?
Basal layer
What is the function of excretion?
To expel waste products
What is the Krause end bulb and where is it located?
Cold receptors, located in eyes, lips, tongue, connective tissue and genitals
What is vasodilation?
When the body gets warm, blood vessels dilate to allow heat to evaporate
What is the healthy pH range of the acid mantle
4.5-5.5
What is included in the basal layer?
Epithelial, Melanocyte, Langerhans, and Merkel cells
What is secretion?
substances produced by the body, that keep it functioning optimally
Where are the pain receptors located?
Located in skin, muscles, bones, blood vessels and some organs
What is vasoconstriction?
When the body is cold, blood vessels constrict, to keep the heat near essential organs
What cells does the stratum corneum contain?
squamous cells also called corneocytes
What is the most abundant cell in the skin?
Keratinocyte
What is excretion also referred to as?
detoxification
What are the proprioceptors responsible for?
Sensing different parts of the body positioned in relation to each other and the environment
When the core body temperature drops the body sends a signal for muscles to shake in small movements to expand energy
What is one of the most important goals as an esthetician?
The integrity of the skin barrier
As the corneocyte moves upward toward the stratum corneum it is held together by filaments called:
Desmosomes
What is the major sweat gland?
Eccrine sweat gland
Where are the Ruffini's corpuscles located?
Dermis, along joints, tendons and muscles
What application can be used for vasoconstriction?
Cool towels, jade roller, cool masks, cold globes
What is the primary function of the skin?
Protection
What is Keratinization?
The chemical conversion of living cells into dead protein cells
What is the skin's most prevalent secretion?
Sebum
