The Integumentary System and Body Membranes
Melanin
produced by specialized cells in this layer
Pigment
substance that gives color ro the skin. Latin for "paint"
Dermis
the deeper layer if the skin, made of a thick and largely of connective tissuse
Melanocytes
the higher the concentration of melanin, the deeper the color of the skin
Epidermis
the outer layer of the skin covering the exterior body surface of vertebrates
Stratum Corneum
the tough outer layer of the epidermis
Mucocutaneous Junction
the transitional area that serves as a point of "fusion" where skin and mucous membranes meet
Hypodermis
tissue layer beneath the dermis; contains adipose tissue, a connective tissue that includes fat-storing cells and blood vessels
Partiel Thickness Burns
1st and 2nd degree burns are also called this
pleurisy
A disorder involving the serous membranes of the lungs
Synovial Fliud
A lubricating substance secreted by the tissue to help protect the ends of the bones from damage by friction.
Apocrine sweat glands
Bacteria feast on secretions from these Glands (be specific)
Second Degree Burn
Blistering, severe pain, fluid loss and swelling, scaring is common but not the complete destruction of dermis in this type of burn
Lanugo
The hair of a newborn infant is extremely fine and soft, Latin for "down"
Mucus
a thick slippery substance produced by the mucous membrane
Membrane
a thin, sheetlike structure that may have many important functions in the body.
Keratin
a tough, waterproof material that prodives cells in the outer layer of the skin with a horny, abrasion- resistance, and protective quality.
Connective Tissue Membrane
composed exvlusively of various types of connective tissue; no epithelial cells are present in this type of membrane
Epithelial Membranes
composed of epithelial tissue and an underlying layer of specialized connective tissue
Visceral
covering of an organ
Peritonitis
inflammation of the peritoneum (membrane lining the abdominal cavity and covering the organs)
Integument
is another name for the skin, and the skin itself is the principal organ of the integumentary system
Dermal- Epidermal Junction
junction between the thin epidermal layer and the dermal layer
Parietal
lining on inside walls of cavity
Synovial Membranes
lining the spaces between bones and joints that move are classified as connective tissue
Pleurisy
painful inflammation of the pleura
Visceral Peritoneum
In dissecting a kidney, you would first have to cut through this outer membrane of the kidney
Third Degree Burn
"Full thickness burn" is this degree
Mucous Membrane
An epithelial membrane that lines a body cavity that opens to the exterior.
Sebum
Associated with every hair for lubrication And protection this secretion's science Name is
Simple squamous epithelial
Cell arrangement, cell type, and tissue type that makes up the serous membranes
Serous Membrane
Composed of two distinct layers of tissue. The epithelial sheet is a thin layer of simple squamous epithelium. The connective tissue layer form a very thin, gluelike basement membrane that holds and supports the epithelial cells.
Membranes function
Cover and Protect the body surface, line body cavities, and cover the inner surface of the hollow organs as the digestive, reproductive, and respiratory passageways
Three Types of Epithelial Membranes
Cutaneous membrane, Serous membranes, Mucous membranes
Eccrine sweat glands
Glands that cause sweaty palms
When does hair grow?
Hair growth begins when cells of the epidermal layer of the skin grow down into the dermis, forming a small tube
Free nerve endings
More than 1000 of these per square inch helps us to respond to painful stimuli
Follicles
Needed for hair growth
Deep Pressure
Pacinian corpuscles sense this
Two types of Serous Membrane
Parietal and Visceral
Pleura and Peritoneum
Pleura: Thoracic Cavities Peritoneum: Abdominal Cavities
Deep and Total Surface
Severity of burn depends on these two things
Cutaneous Membrane
Skin, another word for this. This is the primary organ of the integumentary system. Makes up 16% of body weight
Hair Papilla
Small cluster of cells that produce hair
Bursae
Synovial membranes also line the small cushionlike sacs, found between many moving body parts
dermal Papillae
The upper region, of the dermis characterized by parallel rows of tiny bumps
Meissner's Corpuscles
These are stimulated by a feather on your foot
Kause's end bulbs
These sensory structures are used to sense touch, cold, and the bass from your car stereo
Demal Papille
This highly convoluted layer helps bind the two skin layers together and forms fingerprint ridges
Rules of Nine
Used to evaluate surface area affected by burn
Lanula
Whitish crescent moon between cuticle and nail body
Cyanosis
bluish color of the skin, nail beds, and/or lips due to an insufficient amount of oxygen in the blood
Stratum Germinativam
bottom layer in epidermis, gives rise to other layers. Reproduces skin
