Chapter 2

integumentary system The structures of the integumentary system consist of the skin (and its structures and glands), the nails, and the subcutaneous tissue. This body system covers most of the surface of the body and is the body’s first line of defense against injury and infe
adipose tissue Fatty tissue that is part of the subcutaneous tissue. It contains lipocytes that store fat as an energy reserve.
collagen Firm, white protein fibers in the dermis
cutaneous Pertaining to the skin
cuticle Layer of dead cells that lie along the proximal edge of the nail. The cuticle keeps microorganisms from entering the deeper tissues.
dermis Layer of skin beneath the epidermis. It contains collagen and elastin fibers. It also contains arteries, veins, and nerves, as well as sebaceous glands, sudoriferous glands, and hair follicles.
diaphoresis The process of sweating. The sweat itself is perspiration. Sweat is secreted by the sudoriferous glands. Bacteria on the skin that digest sweat produce its characteristic odor.
elastin Yellow elastic fibers in the dermis
epidermis Thin, outermost layer of the skin. The most superficial part or squamous layer of the epidermis consists of dead cells filled with keratin. The deepest part or basal layer contains constantly dividing cells that are moving toward the surface.
epithelium Type of tissue that includes the epidermis, as well as mucous membranes that line internal cavities that connect to the outside of the body. Also known as epithelial tissue.
exfoliation Normal process of the constant shedding of dead cells from the most superficial part of the epidermis
exocrine gland Type of gland that secretes substances through a duct. The sebaceous (oil) glands and sudoriferous (sweat) glands in the dermis are both exocrine glands.
follicle Structure in the dermis in which each hair forms
hair Structure that grows as a shaft from a follicle in the dermis. Hair cells are filled with keratin.
keratin Hard, fibrous protein in the outermost cells of the epidermis. Keratin is also in the hair and nails.
lipocyte Cell in the adipose tissue of the subcutaneous tissue; it stores fat as an energy reserve.
lunula Whitish half-moon shape that is the visible part of the nail root
melanin Dark brown or black pigment that gives color to the skin and hair.
melanocyte Pigment cell in the epidermis. Melanocyte-stimulating hormone in the anterior pituitary gland in the brain causes melanocytes to produce melanin.
nail bed Layer of living tissue beneath the nail plate. It contains nerves and blood vessels. Also known as the quick.
nail plate Hard, translucent protective covering over the distal end of each finger and toe. It is composed of dead cells that contain keratin. Also known as the nail.
nail root Located beneath the skin of the finger or toe. It produces cells that form the lunula and nail plate.
piloerection Process in which body hairs become erect when the skin is cold.
sebaceous gland Exocrine gland in the dermis that secretes sebum (oil) through a duct. Sebum coats the hair and moisturizes the skin. Also known as an oil gland.
skin The skin is a major part of the integumentary system. The skin consists of two layers—the epidermis and the dermis.
subcutaneous tissue Tissue layer beneath the dermis. It is composed of connective tissue and adipose tissue.
sudoriferous gland Exocrine gland in the dermis. It secretes sweat through a duct that ends at a pore on the surface of the skin. Also known as a sweat gland.
dermatome Area of the skin that sends sensory information through a nerve to the spinal cord
healthcare–associated infection (HAI) Infection that occurs in hospitals and other healthcare facilities when caregivers do not wash their hands. Previously known as a nosocomial infection.
homeostasis Balance, equilibrium, and stability of all body systems and functions
normal skin flora Bacteria that live on the skin and inhibit the growth of disease-causing microorganisms
protection The integumentary system is the body’s first line of defense and protection against injury and infection.
sensation Sensory receptors in the dermis respond to light touch, pressure, vibration, pain, or temperature. The nervous system then relays and interprets skin sensations.
synthesis Process of putting together sunlight and the skin to create vitamin D
thermoregulation Actions of the integumentary system to help control body temperature: the subcutaneous layer conserves body heat, the skin creates heat with goosebumps and piloerection, and the sudoriferous glands secrete sweat to evaporate and cool the body.

herpes Infection caused by the herpes virus. There are clusters of vesicles, erythema, edema, and pain. The vesicles rupture, releasing clear fluid that forms crusts.
Herpes simplex virus (HSV) type 1 causes vesicles on the lips. These tend to recur during illness and stress. Also known as cold sores or fever blisters.
Herpes simplex virus (HSV) type 2 is a sexually transmitted disease that causes vesicles in the genital area. These tend to recur during illness and stress. Also known as genital herpes.

debridement Procedure in which necrotic tissue is removed (debrided) from a burn, wound, or ulcer. This is done to prevent infection from developing, to determine the depth of the wound, or to create a clean, raw surface that is ready to heal or receive a skin graft.
Mechanical debridement consists of putting on a wet dressing, letting it dry, removing the dressing, and pulling off necrotic tissue with it.
Topical debridement uses enzyme drugs to debride by chemically dissolving necrotic tissue. Medically sterilized maggots are used to eat necrotic tissue and the bacteria in it.
Surgical debridement of a large area is done under anesthesia using a scalpel or a curet.
electrosurgery Procedure that uses an electrical current to remove a nevus, wart, skin tag, or small malignant lesion. The electrical current passes through an electrode and evaporates the lesion.
Fulguration The electrode is held away from the skin and transmits the electrical current to the skin lesion as a spark.
Electrodesiccation The electrode is touched or inserted into the skin lesion to deliver the electrical current.
Electrosection A special electrode is used that can cut and remove the lesion.

dermabrasion uses a rapidly spinning wire brush or diamond surface to mechanically scrape away (abrade) the epidermis.
laser skin resurfacing uses a computer-controlled laser to vaporize the epidermis. Also known as a laser peel.
microdermabrasion uses aluminium oxide crystals to abrade and remove the epidermis.
skin turgor assessment Healthcare professionals assess a patient’s level of hydration by testing the skin turgor. A fold of skin pinched between the thumb and fingertips of the healthcare professional should flatten out immediately when released. Dehydration causes the fold of
suturing suturing
Ultherapy® Procedure that uses ultrasound waves directed to the dermis and subcutaneous tissues. It stimulates the production of new collagen to lift and tighten the skin of the face and neck.
