Healing and Temp. Control
How many of the layers of the epidermis see active mitosis?
One
Melanocytes are found deep within this major tissue layer
Epidermis
The Integumentary System includes hair, skin, and what other keratin based structures?
Nails
The most superficial layer of the epidermis
stratum corneum
This layer contains oil and sweat glands
dermis
Name two ways the body reacts to low internal temperature to maintain homeostasis.
Thermoreceptors signal hypothalamus, Vasoconstriction, Sweat glands stay inactive, Muscles contract involuntarily (shivering)
This is what a person has when they lack melanin due to a mutation in their pigment producing genes.
Albinism
This muscle connected to the hair follicle, is under involuntary control
Arrector Pili
The deepest layer of the epidermis
Stratum basale.
List the major layers of the integumentary system, from superficial to deep
Epidermis, dermis, hypodermis
Place these terms in the proper order of the healing process for a cut:
Scab, Wound, Scar, Clot
Wound - Clot - Scab - Scar
Cancer of the pigment producing cells of the skin
Melanoma
The sweat glands that develop during puberty.
Apocrine sweat glands
How many layers make up the epidermis?
4 to 5
What the subdermis is primarily made of (tissue)
Adipose
This standard is used to evaluate the extent of a burn patient's injuries to body tissues.
The rule of nines
People with darker skin have a higher percentage of this pigment.
Eumelanin
Sebaceous glands are associated with this other integumentary structure
Hair
Name two (of the three) layers of the epidermis that have living cells
Daily Double 2X
Stratum basale, stratum spinosum, stratum granulosum
Where on the body would you find no oil glands
Palms and Soles of your feet, and lips
Deep body conditions are maintained around this temperature.
Daily Double 2X
98.6 F
(Anything between 97F - 99F is acceptable)
People with fair skin have a higher percentage of this pigment in their skin.
Pheomelanin
This nerve ending is responsible for sensing light touch.
Tactile (Meissner's) corpuscles
Keratin
This essential nutrient is made in the skin
