Soft Tissue Trauma Flashcards
Epidermis
The outermost skin layer
Sebum
Fatty secretion of sebaceous glands that helps keep the skin pliable and waterproof
Dermis
True skin (corium) The layer of tissue producing the epidermis and housing structures, blood vessels, and nerves
5 Ps associated with Crush Syndrome
Pain Pallor Pulseless Parathesis Paralysis
Sebaceous glands
Glands within the dermis secreting sebum.
Suforiferous glands
Glands within the dermis that secrete sweat
Macrophage
Immune system cell that has the ability to recognize and ingest foreign pathogens
Lymphocyte
WBC that specializes in humoral immunity and antibody formation
Subcutaneous tissue
Body layer beneath the dermis
Lumen
Opening, or space, within a needle, artery, vein, or other hollow vessel
Tendons
Long, thin, very strong collagen tissues that connect muscles to bones
Fascia
A fibrous membrane that covers, supports, and separates muscles and may also unite the skin with underlying tissue.
Types of closed wounds
Contusions
Hematomas
Crush injuries
Tension lines
Natural patterns in the surface of the skin revealing tensions within
Crush Syndrome
Systemic disorder of severe metabolic disturbances resulting from the crush of a limb or other body part
Types of open wounds
Abrasions Lacerations Incisions Punctures Impaled objects Avulsions Amputations
Stages of wound healing
Hemostasis Inflammation Epithelialization Neovascularization Collagen synthesis
Chemotactic factors
Chemicals released by WBC that attract more WBCs to an area of inflammation
Granulocytes
WBCs charged with the primary purpose of neutralizing foreign bacteria
Phagocytosis
Process in which a cell surrounds and absorbs a bacterium or other particle
Hyperemia
Increased blood flow into and through injured or infected tissue, responsible for the reddish skin color, or erythema, associated with inflammation
Epithelialization
Early stage of wound healing in which epithelial
Cells migrate over the surface of the wound
Neovascularization
New growth of capillaries in response to healing
Collagen
Tough, strong protein that makes up most of the body’s connective tissue
