epidermis

the top superficial layer of the skin

dermis

thickest layer of skin; contains sweat/oil glands, hair follicles, blood vessels, and nerves

hypodermis/ subcutaneous layer

a continuous, protective layer of adipose tissue; cushions, connects skin to muscle

follicle

a small, sac like structure in the skin that produces a single hair

sebaceous gland

an oil gland; gland in the dermis that secretes an oily fluid called sebum

sudoiferous gland

a sweat gland; gland in the dermis that secretes sweat

melanocyte

specialized cell found in the skin, eyes and other tissues responsible for the color of the structures

adipose

fatty tissue; made up of fat cells

collagen

the body’s primary structural protein involved in forming many connective tissues and serves as structural glue and scaffolding

normal body flora

microorganisms that normally populate the skin

keratin

a tough fibrous protein present in hair, nails, and the outer layer of the skin that provides structure and protection

lipocyte / adipocyte

a fat cell; specialized cell that stores and metabolizes fat for energy

melanin

a black/brown pigment that is responsible for color in the skin and protects from UV sun rays

excrete

the process of removing metabolic waste, toxins, food, and excess water from the body through urine or stool

secrete

the formation and release of a substance from cells or glands that will be used within/ by the body

purulent discharge

consisting of pus or producing pus

sanguineous discharge

consisting of blood

serous discharge

a thin clear to pale yellow, watery discharge

serosanguineous discharge

consists of blood and a thin, clear to pale yellow watery discharge

pallor

abnormal paleness of the skin

cyanosis

a bluish discoloration of the skin and mucous membranes

jaundice

a yellow discoloration of the skin, mucous membranes, and the sclera due to liver dysfunction

erythema

redness of the skin and mucous membrane

leukoderma

smooth, white patches on various parts of the body due to loss of the natural skin pigment

abscess

a pus containing cavity, usually painful and surrounded by inflamed tissue

callus

a thickened, hardened area of the skin that forms in response to repeated friction/ pressure

cyst

a sac like lesion with a distinct membrane that encapsulated the material inside

decubitus ulcer

ulcerative lesions caused by pressure from bony projections against the skin

lipoma

a protruding mass of fat; a benign tumor of fat under the skin

papule

any small, solid bump on the skin (<1 cm, wart, mole, bug bite)

pustule

small, elevated lesion on the skin containing pus (pimple)

ulcer

a deep erosion of the skin/ mucous membrane marked by inflammation, necrosis, and sloughing off of tissue

vesicle

small blister containing clear fluid

non-blanchable lesion

a skin lesion that does not fade when pressure is applied; can be an ominous sign of blood clotting problems

blanchable lesion

skin that turns pale or white when pressed and then returns to its normal color when the pressure is released

petechia/ purpura

pinpoint to larger-sized red to purple spots of hemorrhage caused by capillaries or small blood vessels leaking underneath the skin

abrasion

an area of skin or mucous membrane that has been scraped off by friction; “road rash”

avulsion

segment of body tissue that is forcibly torn away or detached

clot

clump of platelets, fibrin, and blood cells produced inside a wound to stop bleeding

burn

damage to skin and underlying tissue from exposure to fire, electricity, chemicals, or ultraviolet light

contusion

a bruise; shallow collection of blood under the skin caused by forceful trauma

fissure

narrow crack or tear in tissue or organ

hematoma

swelling or mass of blood within a body tissue; “goose egg”

laceration

cut or tear-like wound of the skin caused by blunt trauma

necrosis

cell death; localized area of tissue death in response to injury/ disease

scab

outer layer of a clot that dries and hardens to form a crust over a wound during healing

scar

fibrous seam that forms when the body replaces damaged tissue with fibrous tissue

puncture wound

a hole into the skin and deeper body tissues made by a pointed object

cellulitis

a bacterial infection of the skin and subcutaneous tissue; causes noticeable skin inflammation
