Very painful pathological condition chacterized by inflammation of the serous membranes that line the chest cavity and cover the lungs.
Epithelial membranes that line the body surfaces opening directly to the exterior. EX: Resporitory, digestive (MOUTH), urinary, and reproduvtive tracts.
Lining the spaces between bones and joints that move are classified as connective tissue memebranes.
Also line the small, cushionlike sacs called BURSAE found between moving body parts.
Structure of the skin
A sheet like organ that covers the body and acts as a barrier between the internal and external enviroment. The skin is composed of two main layers:
The outermost layer of the skin. It is a relatively thin sheet of stratified squamous epithelium.
the deeper of the two layers. It is thicker than the epidermis and is made up largely of connective tissue.
Fatty part of the skin. Also serves as a stored source of energy for the body and can be used as a food souce if required.
The cells of the inner most layer. This enables the skin to repair itself if it is injured.
The deepest cell layer of the epidermis, it is responsible for the production of a pigment called melanin.
A condition charactized by patchy looking areas of light skin resulting from the aquired loss of epidermal melanocytes.
The junction that exists between the thin epidermal layer of the skin above the dermal layer below. The area of contact between dermis and epidermis "glues" them together.
The upper region of the dermis is characterized by parallel rows of peglike projections.
A collection of dilated vessels that may intially apper as a bruise at birth, then grow rapidly during the first year in to a bright red nodule.
Cap-shaped cluster of cells that hair growth begins.
Visible part of a hair is called the shaft.
Involuntary tiny smooth muscle that is attached to the base of a dermal papilla above and to the side of a hair follicle below. This causes goose bumps.
Results from the more than fivefold increase of sebum secretion between the ages of 10 and 19. This oversecretion of sebum results in blockage of sebaceous gland ducts with sebum, skin cells, and bacteria.
Skin plays a key role in regulating the bodys temperature: by regulating sweat secretions and flow of blood close to the body surface.

Highly contagious condition results from staphylococcal or streprococcal infection and occurs most often in small children.
Also called furnucles most often local staphylococcal infections of hair folliclse and are charactereized by large inflamed pustules.,
An autoimmune disease that affects the blood vessels and connective tissues of the skin. Causes the skin to harden and thinken.
Common and chronic skin disorder, characterized by silvery white, scalelike plaques that may remain fixed on the skin for rmonths.
Squarmous cell carcinoma
Slow growing malignat tumor of the epidermis, it the most common type of skin cancer.
Malignant melanoma is the most serious form of skin cancer. Sometime developes from pigmented nevus (mole)
