Integumentary System Flashcards
Body Membrane
A thin pliable layer of tissue covering surfaces, enveloping a part, lining a cavity, or separating or connecting structures or organs.
Epithelial Membrane
line body cavities and passageways, cover internal organs, form inner lining of heart, inner lining of blood vessels
Cutaneous Membrane
the soft outer covering of vertebrates (skin), and guards the underlying muscles, bones, ligaments, and internal organs.
Mucous Membrane
an epithelial tissue that secretes mucus and that lines many body cavities and tubular organs including the gut and respiratory passages.
Serous Membrane
a mesothelial tissue that lines certain internal cavities of the body
Serous Fluid
various bodily fluids that are typically pale yellow and transparent and of a benign nature. The fluid fills the inside of body cavities.
Peritonium
the serous membrane lining the cavity of the abdomen and covering the abdominal organs.
Pleura
a pair of serous membranes lining the thorax and enveloping the lungs in humans and other mammals.
Pericardium
the membrane enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane.
Synovial Membrane
the soft tissue found between the joint capsule and the joint cavity of synovial joints. It secretes the synovial fluid, which fills the joint cavity and lubricates the joint.
Skin
the thin layer of tissue forming the natural outer covering of the body of a person or animal.
Integument
a tough outer protective layer, especially that of an animal or plant.
Keratin
a fibrous protein forming the main structural constituent of hair, feathers, hoofs, claws, horns, etc.
Epidermis
the outer layer of cells covering an organism, in particular, the surface epithelium of the skin of an animal, overlying the dermis.
Dermis
he thick layer of living tissue below the epidermis that forms the true skin, containing blood capillaries, nerve endings, sweat glands, hair follicles.
