Integumentary Conditions Flashcards
skin and whatnot
Epidermis
Thin layer containing mainly keratinocytes, melanocytes, hair follicles, and glands
Dermis
Fibrous and elastic connective tissue encompassed by a ground substance
Langerhans cells
Function in the immune response in the skin
Merkel cells
Sensory receptor cells that detect tactile stimuli
Melanocytes
synthesizes melanin
Sebaceous glands
produces fatty secretions that retains moisture and are found in with every hair follicle
Keratinization
The process that causes hair to form at the hair folicle
Apocrine glands
sweat glands
Papillary Dermis
composed of loosely organized collagen
Reticular Dermis
composed of more bundled collagen
Collagen
Main structural protein found in skin and other connective tissues
Subcutaneous Tissue
tissue that binds skin to organ below it
Arterial Insufficiency
loss of vascular flow to anatomic site causing tissue death (commonly located on the foot or the ankle)
Chronic Inflammation
periods of inflammation longer than 2 weeks
Ground Substance
“cushion” to protect against detrimental compression forces
Hypertrophic scar
contained within the site of injury
Inflammatory phase
phase in which repair of damaged tissue is initiated
clotting cascade occur during this phase, leading to the formation of fibrin clots
Inflammatory skin diseases
patchy sites of acute or chronic inflammation often referred to as dermatitis
symptoms include itching and scaling or the epidermis
Integument
largest organ of the body, 1-4mm in thickness, consisting of two layers (dermis and epidermis)
Plays a role in the body’s temperature control and providing sensory information
Keloid Scar
scars that extend beyond the original boundaries of the wound and that take longer to mature
Neoplastic skin diseases
Benign, malignant or precancerous growth on your skin (e.g. skin cancer)
Neuropathic ulcer
ulcer developed from nerve damaged
Pressure ulcer
wound due to pressure on a tissue causing ischemia
Proliferative phase
stage where epidermal regeneration occurs (where epidermal basal cells proliferate to cause wound coverage)
