Type of Tissue composing the most external layer of skin
Stratified Squamous Epithelium
Layer which provides insulation, anchors skin to underlying tissue
Subcutaneous Tissue
B of the ABCD rule
Border irregularity
Determine fingerprints
Dermal papillae
Functions to provide warmth, protection of eyes and upper respiratory tract (nose)
Hair
Most skin cancers are
Benign
Replacement of skin with artificial or newly grown skin
Grafting
Orange skin pigment
Carotene
Overgrowth of epidermis, plaques with silvery scales
Psoriasis
Actively mitotic epidermal region, deepest layer
Stratum basale
Red skin pigment
Hemoglobin
Inflammation of the skin
Dermatitis
C of ABCD rule
Color
Epidermis layer made up of dead cell remnants completely filled with keratin, accounts for majority of epidermal thickness
Stratum Corneum
Necrotic skin lesions from body resting on bony projections
Pressure ulcer
Cells which produce protein that gives skin its protective properties
Keratinocytes
How nutrients reach the epidermis
Diffusion
Homeostatic imbalance from liver disorder when pigments of bile are absorbed into the blood, causes yellowing of the skin
Jaundice
Lower dermal region
Reticular layer
Burn where only epidermis is damaged
First degree
Pink raised lesions that develop a yellow crust and rupture
Impetigo
D of ABCD
Diameter
Least dangerous but most common type of skin cancer
Basal cell carcinoma
A burn or friction could cause this
Blister
Organelle prominent in cell producing keratin
Ribosome
Feature common to all layers of the epidermis
A vascular
Upper dermal region
Papillary layer
Deep pressure/pain receptor
Pacinian corpuscles
The top layer of epidermis is composed of
Dead cells
Clear layer of epidermis made up of dead cells
Stratum lucidum
Develops spontaneously from pigmented moles or wherever there is pigment, most dangerous and least common type of cancer
Malignant melanoma
Burn where epidermis and upper dermis are burned and blisters form
Second degree
Swear glands located in axillary and genital regions
Apocrine gland
Oil glands are found everywhere in the body except
Palms
Common fungal infection of skin
Athletes foot
A of ABCD rule
Asymmetry
Dead Tissue is scraped off of a burn to improve healing
Debridement
Layer where Squamous cell carcinoma arises
Stratum spinosum
Oil secreted from sebaceous glands
Sebum
Toughened, outer portion of the hair
Cuticle
Glands of these ducts terminate at hair follicles, blockages causes whiteheads and pimples
Sebaceous glands
Vitamin synthesized in the skin
Vitamin D
Homeostatic imbalance causing redness of skin from embarrassment or fever
Erythema
Burn where the entire thickness of skin is consumed
Third degree
Brown to black skin pigment, provides protection from UV light; increases when exposed to sun
Melanin
Layer of skin commonly referred to as “hide”, used for leather
Dermis
