AP 4 2.0 Flashcards
inflamed, plugged sebaceous gland duct, common in acne conditions; also called a blackhead
comedo
primary organ of the integumentary system; the skin
cutaneous membrane
skinfold covering the root of the nail
cuticle
bluish appearance of the skin caused by deficient oxygenation of the blood
cyanosis
tiny bumps in the upper region of the dermis that forms part of the dermal-epidermal junction and produces the ridges and grooves of fingerprints
dermal papillae
junction between the thin epidermal layer of the skin and the dermal layer providing support for the epidermis
dermal-epidermal junction
the deeper of the two major layers of the skin, composed of dense fibrous connective tissue interspersed with glands, nerve endings, and blood vessels; sometimes called the true skin
dermis
relating to an exocrine gland with secretory cells that release secretions by exocytosis without losing part of the cell, as occurs in apocrine glands
eccrine
any of a group of small sweat glands distributed over the total body surface
eccrine sweat gland
“false” skin; outermost layer of the skin
epidermis
membrane composed of epithelial tissue with an underlying layer of connective tissue
epithelial membrane
minor burn causing only minimal discomfort and no blistering; the epidermis may peel but no dermal injury occurs
first-degree burn
a pocket-like structure, such as the cylindrical pocket from which a hair grows or fluid-filled sacs in the thyroid gland or ovary
follicle
A full-thickness burn that destroys both dermis and epidermis and also extends below the subcutaneous tissue to damage underlying tissues such as muscles or bone
fourth-degree burn
burn that (1) destroys epidermis, dermis, and subcutaneous tissue and (2) extends below the skin and subcutaneous tissue to reach muscle and bone
full-thickness burn
a small tube where hair growth occurs
hair follicle
a small cap-shaped cluster of cells located at the base of the follicle where hair growth begins
hair papilla
the loose, ordinary tissue just under the skin and superficial to the muscles; also called subcutaneous tissue or superficial fascia
hypodermis
a malignant neoplasm (cancer) of the skin characterized by a purplish spots
Kaposi sarcoma (KS)
protective protein substance found in hair, nails, outer skin cells, and horny tissues
keratin
sensory receptor with a layered encapsulation found deep in the dermis that detects pressure on the skin surface
Lamellar (pacini) corpuscle
fibrous connective tissue underlying the epithelium in mucous membranes
lamina propria
the extremely fine, soft hair found on a newborn infant
lanugo
crescent shaped white area under the proximal nail bed
lunula
cancerous
malignant
brown skin pigment
melanin
a malignant neoplasm (cancer) of the pigment-producing cells of the skin
melanoma
thin layer or sheet
membrane
the transitional area where the skin and mucous membrane sheet
mucocutaneous junction
