integument Flashcards
Epidermis
outer layer of mostly dead skin cells-stratum corneum. provides protective hardened layer of keratin.
what is our first line of defense?
Intact skin.
dermis
“true skin” consists of connective tissue, blood vessels, hair follicule, sweat glands, elastic fibers, nerves.
subcutaneous tissue.
layer of tissue that attaches to muscle and bone. connective tissue and fat cells.
what gives skin color
melanin
production of melanin is determined by what gland
pituitary
the more melanin the darker the skin
know
protection is the most important thing
know
areas of intense friction causes a ___ usually has fluid underneath it
blister.
Temperature regulation is done by which four ways
radiation, conduction, evaporation, convection.
sensory processing
helps our body process warning signs. Monitors outside enviorment. Specialized nerve endings that respond to pressure, pain, heat and cold.
our skin helps us sythesize certain chemicals of mainly vit d we need UV light so sun exposure is needed
for healthy bones and teeth
where are hair follicles located
in the dermis
humans have hair everywhere but
the palms of their hands, soles of feet, nipples, lips, penis and labia.
hair is formed by hundreds of strands of keratin with amino acids.
scalp hair grows the fastest.
when does hair life slow down and texture change?
midlife.
decreased melanin production results in
gray hair
we inherit our hair type.
know
age, nutrition, wellness, illness, and hormonal levels affect hair production
know
Sebum
lubricates skin and hair from drying out and cracking
sebaceous glands can become blocked. Mostly during puberty.
blockage can appear to be light then later dark. Black head and can turn into a pestual and can be inflammed and cause acne.
finger and toe nails are considered an organ in the integumentary system.
hardened layers of kertain, provide protection, all use them as tools to grasp and pick things up.
assess color, texture and distrubution. know if there is any lesions present and measure them, chart location. Look for abnormal findings like lice or scaling skin.
look at nails and nail beds. note any kind of changes in the color of the nail bed and capillary refill time.
most useful tools when assessing skin and risks is the BRADEN SCALE
it is scored by numbers then add the numbers with a total and will help you design interventions
