What are the layers of the epidermis
Stratum lucidum
Stratum germinativum
Stratum Corneum
Stratum granulosum
Stratum spinosum
The two layers of the dermis
Papillary and reticular
The body functions are similar to what type of machine
Multifunctional machine because of all the functions it performs
The largest organ of the body is the
Skin, integumentary system
Skin histology and physiology, involves the study of
Anatomy, layers, and functions of the skin
The intercellular cement between epidermal cells is made up of
Lipids
Subcutis, or _____ tissue is found below the reticular layer in the dermis
Adipose
What are the 6 primary functions of the skin
Sensation, protection, heat regulation , excretion, secretion, and absorption
What does the skin protect against
Outside elements and microorganisms
An esthetician primary focus is on
Preserving, protecting and nourishing the skin
What does TEWL stand for
Transepidermal water loss
the thickest layer of the skin is called the
dermis
what does EGF stand for and what does it do?
Epidermal growth factor stimulates skin cells to reproduce and heal
The barrier function of the skin includes
Acid mantle
The study of skin physiology and histology includes learning about the
Aging process, UV Damage, hormonal influences and nutrition of the skin health
desquamation is what
shedding of keratinocytes from the skin
flat, scaly cells
how does the skin repair itself?
The acid mantle has a pH of what and why is it important
The acid mantle has an average pH of 5.5 and it is important to stay balanced to protect the body from pathogens and to regulate enzymatic functions
The average body’s internal thermostat is set at
98.6
Define physiology and histology
Physiology is the branch of biology that deals with the normal functions of living organisms and their parts.
Histology is the study of the microscopic structure of tissues.
some states define the esthetician's scope of practice as "not beyond the DEJ" which means that estheticians are to treat
the epidermis only
what are two main glands located in the dermis
sebaceous gland and sudoriferous
The primary cause of wrinkles is the damage and loss of
elastin
Which glands excrete perspiration
Sudoriferous
