epidermis
outer, protective layer of the skin
dermis
layer made of dense, irregular connective tissue that house blood vessels, hair follicles, sweat glands, and other structures
hypodermis or subcutaneous layer
layer below the dermis that is composed of mainly loose connective and fatty tissues
thin skin
4 layers of cells
from deep to superficial: stratum basale, stratum spinosum, stratum granulosum, stratum corneum
thick skin
found only on palms and soles of the feet; has 5th layer called the stratum lucidum between the stratum corneum and stratum granulosum
stratum basale
deepest layer of the epidermis
keratin
intracellular fibrous protein that gives hair, nails, and skin their hardness and water-resistant properties
meissner corpuscles
specialized sensory nerve structure that responds to light and touch
papillary layer
made of loose, areolar connective tissue
reticular layer
composed of dense, irregular tissue; well vascularized and has a rich sensory and sympathetic nerve supply
pacinian corpuscle
specialized sensory nerve structure that responds to vibration
rickets
painful condition in children where bones are misshapen due to a lack of calcium, causing bow-leggedness
osteomalacia
softening of adult bones due to vitamin D deficiency
eccrine sweat gland
type of gland that produces hypotonic sweat for thermoregulation
apocrine sweat gland
associated with hair follicles in densely hairy areas
sebaceous gland
type of oil gland that is found all over the body and helps to lubricate and waterproof the skin and hair

basal cell carcinoma *(BCC)
form of cancer that affects the mitotically active stem cells in the stratum basale of the epidermis; most common of all cancers
squamous cell carcinoma (SCC)
cancer that affects the keratinocytes of the stratum spinosum and presents as lesions commonly found on the scalp, hands, and ears; 2nd most common skin cancer
melanoma
cancer characterized by the uncontrolled growth of melanocytes; develops from a mole; most fatal of all skin cancers
ABCDE for early diagnosis

abinism
genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes; inability of melanocytes to produce melanin
eczema
allergic reaction that manifests as dry, itchy patches of skin that resemble rashes
acne
skin disturbance that occurs on areas of the skin that are rich in sebaceous glands
ringworm (tinea or dermatophystosis)
a circular rash that is itchy and red
psoriasis
chronic autoimmune disorder that results in patches of thick red skin with the appearance of silvery scales
first-degree burn
superficial and only affects the epidermis; heal on its own within a few days
second-degree burn
affects both the epidermis and portion of dermis; result in swelling and painful blistering; heal within several weeks
third-degree burn
fully extends into epidermis and dermis; destroys the tissue and affecting nerve endings and sensory function; appear white, red or black; require medical attention
fourth-degree burn
affects underlying muscle and bone
bedsores or decubitus ulcers
caused by constant, long-term, unrelieved pressure on certain body parts that are bony, reducing blood flow and leading to necrosis
abscess
an enclosed collection of pus in tissues, organs, or confined spaces in the body
adipoctye
fat cell
autonomic
involuntary or unconscious
cauterize
to destroy tissue using a hot or cold instrument, an electrical current, or a chemical that burns or dissolves the tissue to kill tumors or stop bleeding
cellulitis
infection of the skin and subcutaneous tissue, characterized by tenderness, fever, and blisters
contusion
bruise
dermabrasion
a procedure to remove superficial scars using sandpaper or revolving wire brushes
dermatofibroma
fibrous tumor of the skin
diaphoresis
sweating
edema
swelling due to excessive liquid in the tissues
excisional skin surgery
surgical procedure used to remove moles, cysts, skin cancer, and other skin growths using local anesthesia
gangrene
death of tissue due to blood supply loss
hidradenitis
inflammation of a sweat gland
jaundiced
yellow-colored
keloid
raised or hypertrophic scar
nevus
benign growth on the skin that is formed by a cluster of melanocytes
nodule
growth or lump that may be malignant or benign
onychocryptosis
ingrown nail
onychomycosis
fungal infection of the nail
onychophagia
nail biting
pallor
unnatural paleness of the skin
paronychia
infection of the skin around the nail
pruritus
itching
rhytidoplasty
excision of wrinkles of the skin
scar
collagen-rich skin formed after the process of wound healing that differs from normal skin
staphylcoccus aureus
bacteria that is commonly found in minor skin infections and in the nose of some healthy people
streptococcus
bacteria that causes strep throat
