Disease And Disorders
Lesion On The Skin
* A lesion on the skin is a mark on the skin that may indicate injury or damage the changes that structure of tissue or organs
Primary Lesions Of The Skin
* Primary lesions are lesions that are different color than the color of the skin and lesions that are raised above the surface of the skin. They’re often different tatied by size in layers of the skin affected. These may require medical referral.
Bulla
* A bulla is a blister containing a watery fluid, similar to vesicles, but larger, it requires a medical referral.
Cyst
* A cyst is a closed, abnormally developed sac, containing fluid pus, semi fluid, above or below the skin it requires a medical referral.
Macule
* A macule is a flat spot or discoloration on the skin.
Nodule
* A nodule is a solid bump larger than 1cm that can be easily felt
Papual
* A papule is a small elevation on the skin that contains no fluid, but may develop pus
Pustule
* A pustule is raised inflamed papule with a white or yellow center containing ous in the top lesion.
Tumor
* A tumor is an abnormal mass varying in size, shape, and color. Any type of abnormal mass was not cancer. Require medical referral.
Vesicle
* A vesicle is a small blister or sac containing clear fluid, lying within or just beneath the epidermis.
Wheal
* A wheal is an itchy, swollen lesion that can be caused by a blow, scratch, bite of insect, skin allergy.
Crust
* A crust is dead cells that form over a wound or blemish while healing, accumulation of sebum and pus, sometimes mixed with epidermal layers.
Secondary Skin Lesions
* Secondary skin lesions are characterized by piles of material on the skin surface, such as a crust or scab, or by depression in the skin surface such as ulcer.
Excoriation
* Excoriation is a skin sore or abrasion produced by scratching or scraping.
Fissure
* A fissure is a crack in the skin penetrating into the dermis.
Keloid
* A keloid is a thick scar resulting from excessive growth of fibrous tissue.
Scale
* A scale it’s a thin, dry or oily plate of epidermal flakes, excessive dandruff.
Scar
* A scar is a slightly raised mark on the skin formed after an injury or lesson of the skin heated.
Ulcer
* An ulcer is an open lesion on the skin or mucous membrane of the body, followed by loss of the skin depth and possibly weeping fluids or pus. Requires medical referral.
Open Comedo
* Also known as a blackhead, is a hair follicle filled with keratin and sebum, comedones appear most frequently on the face especially in the t-zone. When the sebum of the comdeo is exposed to air. It oxidizes and turns black.
Closed Comedo
* When the follicle is closed and not exposed to the environment, the sebum remains a white or cream colored and appears as a small bump just under the skin surface. Also known as a white head.
Mila
* Are beginning, keratin filled cyst that appear just under the epidermis and have non-visible opening. They resemble small rounded sesame seeds.
Acne
* Is a skin disorder characterized by chronic inflammation of the sebaceous glands from retained secretions and bacteria known as propionibacterium acnes (P.Acnes) the scientific term of acne bacteria.
Sebaceous Cyst
* Is a large, protruding, pocket like lesion filled with sebum. Sebaceous cyst are frequently seen on the scalp and back, and may be surgically removed by a dermatologist.
Rosacea
* Rosacea is a chrome condition that appears on the nose and the cheeks. Characterized by redness, telangiectasia which is duration of blood vessels, and formation of papules and pustules. Factors that active rosacea are spicy food, caffeine, alcohol, exposure to extreme heat, cold, or sunlight, and stress.
The Structure Of Skin
Blood Capillary Vessels
* Consist of aritenes, veins and capillaries, found in the dermis. Carry nutrients and oxygen.
Never Ending
* Found in the dermis. Respond to pain, pressure, heat and touch.
Sweet Pore
* Opens onto the epidermis. Releases sweat to cool the skin. Also removes waste products.
Hair Root
* Found in the dermis. Attach the bulb.
Hair Shaft
* The part of the hair above the skin or scalp.
Sebaceous Glands
* The gland that produces sebum, the hair's natural oil, which is secreted into the follicle where it lubricates the hair and the skin of the scalp.
Epidermis
* The outer layer of the skin. It consists of five layers. Horney layer, clear layer, granular layer, prickle cell layer, basal layer.
* Horny layer, granular layer, prickle cell layer. These layers are dead and constantly being shredded.
Clear Layer
* Three to four rows of dead skin cells which flattered. Only found on the palms of the hands and soles of the feet. Found above the granular layer. Protected in area of friction.
Basal Layer
* Deepest Layer of the epidermis. Constantly producing new cells.
Papillary Layer
* Join the epidermis and dermis layers together. Has a rich supply of blood vessels and nerve endings.
Arrector Pili Muscle
* Muscle to erect hair. If you are cold or frightened, the muscle contracts (pull tight) and the hair stands on end creating “goose pimples on the skin”.
Subcutaneous Layer
* Fat layer protects muscles, bones and internal organs, provides insulation and sources of energy.
Lymph Vessels
* Transport lymph fluid through a series of glands to filter toxins and waste.
Never Fiber
* Leads from never ending and connects to nervous system.
Sweet Glands
* The glands that produce sweat cool, the body.
