a condition of the skin resulting from the inability to synthesize melanin
albinism
completely cutting or tearing off of a body part
amputation
coiled tubular glands that usually open into hair follicles of the axillae and genitalia, as well as around the anus

wound in which flaps of skin and tissue are torn loose or pulled off completely
avulsion
the result of heat or other thermal injury to the skin
burn
the layer of skin located directly immediately above the hypodermis
dermis
merocrine sweat glands distributed over the body that promote cooling of the body
eccrine glands
granules within the stratum lucidum that are formed from keratohyaline and are eventually transformed to keratin

the superficial, outer layer of the skin that contains numerous nerve vessels, but no nerve endings
epidermis
muscle attached to the base of the hair that pulls the hair perpendicular to the surface of the skin in cold or threatening situations
erector muscle
burns involving only the epidermis, also called superficial burns
first-degree burns
burns that involve the hypodermis and possibly bone, or internal organs, also called third degree burns

threadlike, keratin-containing appendage of the outer layer of the skin
hair
a tubular cavity beneath the skin in which hair develops
hair follicle
the portion of hair that extends above the skin
hair shaft
referring to below the skin
hypodermic
the layer of tissue immediately below the dermis, also called the subcutaneous tissue
hypodermis
a smooth cut, usually made by a sharp object
incision
the body's external surface, including the skin, nails, hair, and sweat and oil glands
integumentary system
a protein in the skin that is responsible for the strength and permeability of the epidermis
keratin
the cells in the epidermis that produce a protein called keratin
keratinocytes
a precursor of keratin that is located in the stratum granulosum of the epidermis
keratohyalin
a wound with a smooth or jagged edge, resulting from a tearing or scarping action
laceration
the white crescent-shaped structure at the base of the nail body
lunula
the dark pigment in skin that protects the skin from the sun's ultraviolet rays
melanin
epidermal cells that contribute to skin color by producing a dark pigment called melanin
melanocytes
glands that produce a solution containing salt and urea that is secreted directly onto the surface of the skin through sweat pores
merocrine sweat glands
a flattened structure at the end of each finger and toe made of keratin from the epidermis
nail
the portion of the nail over which the nail body lies
nail bed
burns that involve the epidermis and a portion of the dermis; also called second degree burns

wound made by a sharp instrument that passes through the skin, affecting all tissues in its path
penetrating wounds
glands that produce sebum and are located in the dermis of the entire body, except for the palms and soles
sebaceous glands
material produced by sebaceous glands that contain a combination of fat and cellular debris
sebum
burns that involve the epidermis and a portion of the dermis, also called partial thickness burns
second-degree burns
the flat sheets of cells that make up the epidermis
squamous epithelium
the outer layer of the epidermis, which contains about 25 layers of dead cells that continuously shed as new cells push upward
stratum corneum
the innermost layer of epidermis
stratum germinativum
the layer of epidermis between the stratum lucidum and the stratum spinosum that is composed of flattened cells that contain granules of keratohyalin
stratum granulosum
the first inner layer of the epidermis, it is found only in the thick epithelium of the palms of the hands and the soles of the feet
stratum lucidum
the layer of epidermis between the stratum granulosum and the stratum germinativum that contains cells known as keratinocytes, which synthesize the keratohyaline, a precursor of keratin
stratum spinosum
the layer of soft tissue immediately below the dermis, also called the hypodermis
subcutaneous tissue
burns involving only the epidermis, also called first-degree burns
superficial burns
pores in the skin in which sweat in secreted
sweat pores
burns that involve the hypodermis and possibly bone, muscle, or internal organs; also called full-thickness burns
third-degree burns
break in the integrity of the integumentary system
wounds
