The skin and its layers make up this body system
What is the integumentary system
100
These are the five layers of the epidermis
What is the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum.
100
found in the dermis, these cells are responsible for the formation of fibers and aid in the production of collagen and elastin
What are fibroblast cells
100
the lowest layer of the dermis, it is in direct contact with the next layer of skin, the subcutaneous layer
What is the reticular layer
100
the physical process of removing dead skin cells with an abrasive product
What is mechanical exfoliation
200
a protein substance that is a primary component of skin cells
What is keratin
200
the toughest layer of the skin, it is continually shedding and being replaced by new cells from layers below
What is the stratum corneum
200
touch receptors or sensory cells, that are found in the stratum germinativum
What merkel cells
200
these types of glands produce sweat, a mixture of water, urea, electrolytes and lactic acid
What are sudoriferous glands
200
the process of using products such as enzymes or acids to dissolve the intercellular cement
What is chemical exfoliation
300
The three layers of the skin
What is subcutaneous, dermis, epidermis
300
This is the layer of skin where the organelles of the cell begin to disintegrate and the cell dies
What is the stratum granulosum
300
found in the stratum spinosum, these cells help protect the body from infection
What are Langerhans cells
300
This male hormone affects the production of sebum, secreted by sebaceous glands
What is androgen
300
this is a mixture of fatty acids that keeps the skin, soft
What is sebum
400
keratinocytes remain tightly interconnected by intercellular connections called
What are desmosomes?
400
layer of skin in which keratinocytes are densely packed with clear keratin. This creates epidermal ridges, or whorls, and creates our fingerprints
What is the stratum lucidum
400
These cells are located in the dermis and respond to allergies by releasing histamines
What are mast cells
400
these glands are responsible for thermoregulation
What are eccrine sweat glands
400
the substance that binds, adds structural strength and mediates biochemical reactions between cells
What is intercellular cement
500
These are the six functions of the skin
What are protection, absorption, secretion, excretion, heat regulation and sensation
500
the basal cells in the basement membrane of this layer eventually become kertinocytes
What is the stratum basale or germinativum
500
these corpuscles detect light pressure and cold
What are meissners corpuscles
500
this layer is rich in blood vessels and capillaries, which provide nutrition to the upper layers
What is the papillary layer
500
the six factors affecting skin absorption
What is: Condition of stratum corneum Hydration Level Oiliness of the skin Size of products molecules Temperature of the skin Pore Size
