Epithelial Membrane
Cutaneous, Mucous, and Serous
Connective Membrane
Describe the Cutaneous membrane
dry membrane.
outermost protective boundary
superficial epidermis is composed of keratinized stratified squamous epithelium
underlying dermis is mostly dense connective tissue
Describe the Mucous membrane
stratified squamous
around mouth and esophagus
can be reached from an opening on the exterior (mouth, nose,ears,uretha,etc.)
often adapted for absorption and secretion
Describe the Serous membrane
layer of simple squamous epithelium
lines open body cavities that are CLOSED to the exterior
What are the two general types of serous membrane?
Visceral and parietal
lines ventral cavity
layer covers outside organ
Specific Serous membranes include...
peritoneum, pleura, and pericardium,
Where can peritoneum membrane be found?
the abdominal cavity
Where can the pleura membrane be found?
around the lungs
Where can the pericardium membrane be found?
around the heart
Connective tissue membrane is...
What is included in the integumentary system?
skin derivatives
sweat glands
oil glands
What are the layers of the epidermis?
Stratum Basale, Stratum Spinosum, Stratum Granulosum, Stratum Lucidum, and Stratus Corneum
Which layer of the epidermis is undergoing mitosis?
Stratum Basale
Where can the Stratum Lucidum be located?
hairless areas
palms of hands
soles of feet
Describe the Stratum Corneum.
outermost layer of epidermis
shingle like dead cells are filled with keratin proteins that prevent water loss from skin
What are the layers of the dermis?
Papillary and Reticular
Describe the Papillary layer.
projections called dermal pappilae
capillary loops
house pain receptors
Describe the Reticular layer.
blood vessels
sweat and oil glands
deep pressure receptors
Describe the dermis.
collagen and elastic fibers located throughout the dermis
Blood vessels
body temperature
pigment produced by melanocytes
found in stratum Basale
Sebaceous Glands
oil glands
Sweat glands
axillary and genital areas
stress and pain regulated
found everywhere
heat regulated
heat evaporates from skin with sweat
Oil does what?
kills bacteria
lubricates skin
prevents brittle hair
Composition of sweat.
water salts and vitamins some metabolic waste ammonia urea uric acid fatty acids and proteins
What is the most important thing to remember about hair and nails?
It contains keratin
What is the rule of 9
body divided into 11 areas each area represents 9% of the body
Describe a first degree burn and give an example
Sunburn is an example
only epidermis is damaged skin is red and swollen
Describe and give example of second degree burn
damaged epidermis and upper dermis and the skin blisters
A blistering sunburn is an example
Describe a third degree burn
Get your entire skin layer turns in grey white black and grafting must be done
What are the two ways that cancer is classified?
Benign and malignant
True or false skin cancer is the most common type of cancer
Basale Cell Carcinoma
least malignant
most common
cells of stratum Basale are altered so that they cannot form keratin and longer honor the boundary between epidermis and dermis
sun exposure
Squamous Cell Carcinoma
arises from the sounds of the stratum spinosum
Gradually forms a shallow ulcer with firm raised border
Grows rapidly
Usually found around the scalp ears dorsum of hands and lower lip
Malignant melanoma
Cancer of melanocytes
Only about 5 percent of skin cancer
Often deadly
Appear spontaneously
Some developed from pigmented moles
Spreading brown to black patch. Grows quickly
50 percent survival rate
What is the A B C D E rule
A) Asymmetry
B) Borders
C) Color
D) Diameter (6mm)
E) Elevation
how to determine if a mole is potentially cancerous
