Acid mantle |
Very fine, slightly acidic film over the epidermis. The acid mantle and the stratum corneum make the skin less permeable to water, and indirectly protects the skin from micro organisms |
|
Adipose tissue |
Vascular, loose connective tissue that stores fat and provides energy, cushioning and insultation |
|
Blister |
Collection of fluid at the junction between the dermis and the epidermis, due to friction |
|
Bony prominence |
Areas of the body, heel/ sacrum, which are protected by a relatively thin layer of subcutaneous tissue only. Bony prominence tend to be susceptible to pressure ulcers |
|
Callus |
Localized build up of stratum corneum cells due to pressure or fiction |
|
Cell adhesion |
The binding of a cell to a surface, extracellular matrix or another cell using cell adhesion molecules such as selectins, integrins, and cadherins |
|
Collagen |
Main support protein of the skin |
|
Elastin |
Protein in connective tissue that is elastic and allows many tissues in the body to resume their shape after stretching or contracting |
|
Extremity |
An arm or a leg; the arm is usually identified as an upper extremity, the leg as a lower extremity |
|
Fascia |
Fibrous connective tissue that separates and surrounds structures, and facilitated movement between adjacent structures |
|
Full- thickness wound |
Wound that extends through the epidermis and dermis and into the subcutaneous tissue |
|
Hair |
Epidermal appendages located within the dermis that are made of soft keratin |
|
Histamine |
Chemical mediator released by mast cells which causes vasodilation and increased vessel wall permeability, and attracts other cells to the area |
|
Keratin |
A protein produced by keratinocytes. Nails are made of hard keratin; hair is made of soft keratin |
|
Keratinocytes |
Epidermal cells that resurfaces a wound and produces keratin |
|
Langerhans’ cell |
Epidermal cell that assists with infection control |
|
Macrophage |
Cell that directs the repair process, secretes growth factors and enzymes and destroys bacteria and debris |
|
Mast cell |
Cell that helps initiate inflammation through secretion of histamine, enzymes, and chemical mediators |
|
Melanin |
Dark pigment of the skin and hair, formed by melanocytes |
|
Melanocytes |
Pigment-producing cell within the epidermis |
|
Nail |
Epidermis appendage made of hard keratin and located at the dorsal tips of the digits |
|
Merkel’s cell |
Sensory receptor within the epidermis providing information on light touch |
|
Papillary dermis |
This superficial dermal layer consisting of loosely arranged connective tissue |
|
Partial- thickness wound |
Wound involving the epidermis and part of the dermis |
|
Phagocytizing |
Process of engulfing and destroying bacteria and/ or debris |
|
Reticular dermis |
Thick, deep dermal layer consisting of dense, irregularly arranged connective tissue |
|
Sebaceous gland |
Oil gland, epidermal appendage located within the dermis |
|
Sebum |
Oily substance that lubricates the skin and hair |
|
Stratum basale |
Deepest epithelial cell layer; contains continuously dividing cells |
|
Stratum corneum |
Outermost epithelial call layer; consists of dead keratinocytes |
|
Stratum granulosum |
Epithelial cell layer located between the stratum spinosum and stratum lucidim |
|
Stratum lucidum |
Epithelial call layer located between the stratum granulosum and stratum corneum |
|
Stratum spinosum |
Epithelial cell layer located between the stratum basale and stratum granulosum |
|
Subcutaneous tissue |
Adipose tissue and fascia, located beneath the dermis; helps support the skin |
|
Sudoriferous gland |
Sweat gland; epidermal appendage located within then dermis |
|
Superficial wound |
Wound involving only the epidermis |
|
Tendon |
Fibrous cord of connective tissue continuous with the fibers ina muscle and attaching the muscle to bone orncratilage |
|
White blood cell |
Cell that helps fight infection. These consist of Neutrophils, lymphocytes, monocytes, eosinophils and basophils |
