---|---|---|---|---|
What is the epidermis
The uppermost superficial layer of the skin comprised entirely of epithelial cells
|
What is resistance to infection
The skin's pH of 4-6, known as the acid mantle helps with this skin function
|
What are sebaceous glands
This gland produces oily secretions called sebum that contain broken-down cells
|
What is a sunburn
This injury is from UV damage to underlying skin and results in inflammation
|
What is skin cancer
This condition is induced by UV rays from the sun
|
What is the stratum lucidum
Thin translucent zone seen only in thick skin
|
What are keratinocytes
These cells are filled with keratin, serve as a water barrier and are produced by stem cells in the stratum basale
|
What are the five glands of the skin
The merocrine sweat glands, apocrine sweat glands, sebaceous glands, ceruminous glands, and mammary glands
|
What are melanocytes
This cell creates skin pigmentation
|
What is a 3rd degree burn
This injury causes complete damage of the most superficial dermis, penetrates down to the dermis and the hypodermis, is life-threatening and has astronomical infection rates
|
What is the hypodermis
The bottom fatty layer of skin that functions as an energy reserve, cushion, and for heat retention
|
What is the dermal papillae
These are extensions of the dermis into the epidermis that forms the ridges of the fingertips
|
What are Merocrine glands
The body contains millions of these sweat glands to cool down the body
|
What is cyanosis
This condition results in a purple/blue pigmemented skin color due to improper circulation of blood
|
What is malignant melanoma
The most deadly type of skin cancer, often arises from melanocytes of a mole
|
What is the Dermis
The vascular middle layer of skin, almost exclusively dense irregular tissue
|
What is the dermis
This section of skin contains the papillary layer and the reticular layer
|
What are apocrine glands
This is a sweat gland that contains fatty acids
|
What is albinism
A genetic condition where the body is incapable of producing melanin
|
What is the ABCD rule
The rule to check to see if moles may be cancerous
|
What is the epidermis
The cell layers stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale make up this skin layer
|
What is alopecia
This is the thinning of balding of hair
|
What are ceruminous glands
This gland is only found in the external ear canal and combines with sebum to produce earwax
|
What is vessel dilation
Causes "blushing" and occurs from alcohol, embarrassment, anger or exercise
|
What is a 2nd degree burn
This injury involves blisters and causes the seperation between the epidermis and dermis
