What is the main structure of the integumentary system?
skin
What 8 things does skin do?
1. maintains homeostasis; 2. protective covering; 3. retards water loss; 4. regulates body temperature; 5. houses sensory receptors; 6. contains immune system cells; 7. synthesizes chemicals; 8. excretes small amounts of wastes
What do skin cells do?
help produce vitamin D for normal bone and tooth development
What do kertinocytes do?
they are cells that produce substances that stimulate the development of some white blood cells
What are the three layers of the skin?
epidermis, dermis, subcutaneous layer
What is the epidermis?
the layer of dead cells on top of the dermis
What is the dermis?
The main, living part of the skin
What is the subcutaneous layer?
The bottom layer of the skin that is mostly fat and lessens with age
What is the subcutaneous layer also known as?
the hypodermis
What does the epidermis lack?
blood vessels
Which layer of the skin is keratinized?
epidermis
Where is the epidermis thickest?
on the palms and soles
What provide melanin to the epidermis?
Melanocytes
The epidermis is made up of what kind of epithelia?
stratified squamous epithelia
What are the five layers of the epidermis in order?
1. stratum corneum; 2. stratum lucidum; 3. stratum granulosum; 4. stratum spinosum; 5. stratum basale
Which layer of the epidermis is found only in thick skin, like palms and soles?
stratum lucidum
What two factors determine skin color?
Heredity and environment
What two genetic factors affect skin color?
1. Varying amounts of melanin; 2. Varying size of melanin granules
What three environmental factors affect skin color?
1. sunlight; 2. UV light from sunlamps; 3. x-rays
What three physiological factors influence skin color?
1. Dilation of dermal blood vessels; 2. Constriction of dermal blood vessels; 3 Accumulation of carotene
What are hair follicles?
dead epidermal cells that have a tube-like depression and extend into the dermis
What are the three parts of the hair follicle?
1. hair root; 2. hair shaft; 3. hair papilla
What is the function of a nail?
protective covering
What are the three parts of a nail?
1. nail plate; 2. nail bed; 3. lunula
What are sebacious glands?
holocrine glands that secrete sebum (oil)
What are sebacious glands usually associated with?
hair follicles
Where are there no sebacious glands?
palms and soles
What are sweat glands also known as?
sudoriferous glands
What are sweat glands?
widespread glands in skin that originate in hypodermis
What are the four types of sweat glands?
1. eccrine; 2. apocrine; 3. ceruminous; 4. mammary
Why is body temperature regulation important?
even slight shifts can disrupt metabolic reactions
What is hyperthermia?
abnormally high body temperature
What is hypothermia?
abnormally low body temperature
Inflammation is...
a normal response to injury or stress
What happens during inflammation?
blood vessels in affected tissues dilate and become more permeable, allowing fluids to leak into damages tissues
What can happen to inflamed skin?
it can redden, swell, become warm, or become painful
What is a first-degree burn?
It only reaches the epidermis and is a superficial and partial-thickness burn
What is a second-degree burn?
Reaches the dermis, but is still only partial-thickness
What is a third degree burn?
Reaches the hypodermis and is a full-thickness burn that requires an autograft, homograft, or skin substitute
As a person ages, their skin...
becomes scaly
forms age spots
has a thinner epidermis, hair, reduced dermis
loses fat
wrinkles
sags
secretes less oil
produces less melanin
loses hair follicles
impairs nail growth
declines sensory receptors
trouble controlling body temp., activating Vitamin D

What is albinism?
When a person has no melanin
Is albinism a virus, bacteria, or genetic?
genetic
Is a wart a virus, bacteria, or genetic?
virus
Can warts spread?
yes

What is another name for the sebacious gland?
sebum
Which sweat gland activates during puberty?

What does the apocrine gland do?
Responds to stress by causing odor
Where are apocrine glands mostly found?
groin and armpit
Where are apocrine glands from?
hair follicles
