Integumentary system
asymmetry, border, color and diameter
Warning signs of malignant melanoma are identified with the ABCD rules of examination:
First-degree burns
cause minimal damage to the epidermis.
synovial
connective tissue membrane
lanugo
fine hair that covers new born"s body
sweat glands
found primarily in the skin in the axilla are the apocrine.
sebaceous
gland that grows where hair grows and secretes a skin lubricant
mucus
Epithelial cells of most mucous membranes secrete a thick material known as:
Connective Tissue Membrane
Synovial membranes belong to the category of connective tissue membranes because they contain only connective tissue and line joint cavities. Because synovial membrane does not contain any epithelium, it cannot be classified as an epithelium membrane, yet there are similarities: Like serous membrane, synovial membrane lines cavities that do not lead to the outside. Like epithelial membranes, synovial membrane secretes a fluid to prevent friction. Synovial membranes secrete synovial fluid, which flows into the joint cavities and lubricates the bones so that they can move freely and effortlessly.
eccrine
type of sweat gland distributed over the entire body surface
keratin
waterproof also protects the body from excessive fluid loss.
subcutaneous tissue
A thick layer of loose connective tissue and fat supports the layers of the skin.
hair papilla
Hair growth begins from a small, cap-shaped cluster of cells called
decubitis
Lying down
free nerve endings.
Receptors that respond to pain and changes in temperature
Squamous cell carcinoma Basal cell carcinoma Malignant melanoma
The most common types of skin cancer are:
viseral
The portion of serous membrane that covers surfaces of organs found in body cavities
parietal
The portion of serous membrane that lines body cavities
peritoneum
The serous membrane of the abdominal cavity
erythema
a reddish discoloration to the skin
stratum germinativum
also known as innermost epidermis
stratum corneum
also known as outer epidermis
urticaria
another name for hives
dermatosis
any disorder of skin
Fourth-degree burns
are full thickness burns that extend below the subcutaneous tissue to reach muscle or bone. Treatment may require extensive skin grafting, and even amputation of limbs.
Meissner corpuscles
are located in the dermis
sebaceous glands
are located in the dermis
goose pimples
arrectorpili
dermis
deeper layer of skin The dermis is considered the true skin. It lies beneath the epidermis, is much thicker, and is composed mainly of connective tissue. The dermis is where the majority of skin appendages—such as hair follicles, sweat, and sebaceous glands—are located. Nerves and capillaries of the skin emerge from this area as well
fingerprints
dermal papillae
Second-degree burns
descend into the dermis and may cause scarring.
Third-degree burns
destroy both epidermis and dermis and extend down into the subcutaneous tissue; these can be very serious. If these burns are too severe or cover a large area of the body, death may occur.
stratum germinativum
is located in the epidermis
skin
largest and most visible membrane is the cutaneous membrane he skin is described as the body's first line of defense, but it has many other functions. The three most important are: Protection Temperature regulation Sense organ activity
tinea
medical term for ringworm
Serous Membrane
membrane found in closed body cavities Serous membranes are epithelial membranes that are located on surfaces of closed body cavities. They secrete a thin, watery fluid that helps reduce friction and serves as a lubricant when the organs rub against each other or the cavities that contain them. Serous membrane is composed of two distinct layers of tissue: The parietal layer lines the walls of body cavities, much like wallpaper. The visceral layer covers the surfaces of organs found in body cavities.
cutaneous membrane
membrane more commonly know as skin utaneous membrane is a subdivision of the epithelial membrane. It is also known as the skin and is the primary organ of the integumentary system. Cutaneous membrane covers the surface of the body and consists of stratified squamous epithelium and the underlying connective tissues. The outer layer of skin (epidermis) protects the body from invading microorganisms, and the underlying connective tissue layer (dermis) contains the majority of the skin appendages. Cutaneous membrane is thick, relatively waterproof, and dry.
mucous
membrane that lines body surfaces leading to the exterior of the bodymembranes lining the respiratory, digestive, urinary, and reproductive systems.
epidermis
outermost layer of skin he epidermis consists of tightly packed epithelial cells. Note how they are arranged in distinct layers. Approximately each month, a new layer of epidermis develops. Epidermal cells are constantly being sloughed off as a result of our everyday activities such as bathing, friction with clothing, and exercise. New cells are formed quickly to protect and provide the waterproof covering for the body's surface. Although it has no blood supply of its own, oxygen and nutrients diffuse from the dermal blood vessels into the epidermis.
pustules
pus filled pimples
exocrine glands
secretions pass into a system of ducts that lead ultimately to the exterior of the body. Two major exocrine glands are associated with the skin: Sebaceous glands secrete oil (sebum) and are found in all areas of the body that have hair. Sudoriferous glands, or sweat glands, are the most numerous of the skin glands and are classified into two groups: Eccrine Apocrine
Kaposi sarcoma
significant number of reported AIDS cases. Many pathophysiologists believe that this skin cancer virus or similar agent is transmitted in some patients along with HIV.
scleroderma
skin disorder means hard skin
dermatitis
skin disorders that involve inflammation of the skin
pacini corpuscle
skin receptor located deep in the dermis
bursae
small cushion-like sacs that are found between moving body parts
