integumentary Flashcards
List three functions of the skin
Protects from infection, protects from dehydration, data collection / sense of touch.
List the three layers of skin
Epidermis, dermis, hypodermis
This layer of skin contains everything an organ needs to survive
dermis
True skin is a another term for
dermis
Which layer of skin contains sweat glands
dermis
Describe the dermis layer
Comprised of living cells, contains a blood supply and sweat glands
What is in the hypodermis
Arteries veins ant fat cells
List the all possible layers of the epidermis from surface in
Stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale
List the two types of skin
Thick skin, thin skin
Where is thick skin found
Palms/fingers and bottom of the feet
How long does it take living skin to be pushed up to the surface and flake off
3-5 weeks
melanocytes manufacture
Melanin - a pigment
Where are melanocytes located
Stratum basale
Melanin protects the skine from
ultraviolet radiation
What are the two types of sweat glands
eccrine and apocrine
Where does apocrine sweat go
Through ducts and on to hair follicles in the armpits and pubic region
Where does eccrine sweat go
through ducts to the surface of the skin
Another name for eccrine sweat glands
merocrine
apocrine sweat can result in
Odorous Bacteria growth
Describe ohms law
Current (I) = voltage / resistance
How does this impact poly
A constant voltage delivered to the surface of the skin results in changing currents as sweat is produced.
Sweat glands in the palmer area reflect
Cognitive and emotional responses to stimulus
SCL
Skin conductive level - the conductivity of skin at homeostasis
SCR
Skin Conductive Response - the conductivity of skin in response to a question
