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
