Integumentary System Flashcards
Covering and lining membranes, including the skin and mucous membranes.
Epithelial Membrane
Your skin.
Cutaneous Membrane
Lines all body cavities that open to the exterior.
Mucous Membrane
Lines body cavities that are closed to the exterior, except for the dorsal and joint cavities.
Serous Membrane
Separates the serous layers.
Serous Fluid
The lining of the abdominal cavity and covers its organs.
Peritoneum
Membrane that surrounds the lungs.
Pleura
Membrane that surrounds the heart.
Pericardium
Line the fibrous capsules surrounding joints, help cushion movement during muscle activity.
Synovial Membrane
Protects the interior of the body from exterior bacteria, repairs itself, etc.
Skin
Another word for the skin. Keeps good things in and bad things out.
Integument
Skin is full of this, prevents water loss from the body.
Keratin
The outermost layer of the skin, full of keratin so it can harden and prevent water loss and protect against cuts, etc.
Epidermis
Made up of dense connective tissue that connects it to the epidermis.
Dermis
The deepest layer of the epidermis, cells divide her constantly, receives the most nutrients.
Stratum Basale
The fourth layer of the epidermis.
Stratum Spinosum
The third layer of the epidermis. Last layer skin cells go before they die and form the stratum lucidum.
Stratum Granulosum
Dead skin cells form this layer.
Stratum Lucidum
Dead skin cells that are full of keratin. Outermost layer of the skin. AKA horny cells.
Stratum Corneum
Pigment that colors the skin.
Melanin
Oil glands.
Sebaceous Glands
The oil that the Sebaceous Glands secrete.
Sebum
Produce sweat.
Eccrine Glands
Found in the genital areas of the body. Secretes fatty acids and proteins into hair follicles.
Apocrine Glands
Compound structures that make up the hair of the body.
Hair Follicles
Connects each side of the hair follicle to the dermal tissue.
Arrector Pili
An itchy, red, peeling condition of the skin between the toes, resulting from fungus infection.
Athlete’s Foot
Inflammation of hair follicles typically on the dorsal neck. They are composite boils caused by bacterial infection.
Boils and Carbuncles
Inflammation of hair follicles typically on the dorsal neck. They are composite boils caused by bacterial infection.
Boils and Carbuncles
Small fluid-filled blisters that itch and sting, caused by a herpes simplex infection. Usually around the lips and in the mouth.
Cold Sores
Itching, redness, and swelling of the skin that eventually leads to blistering. Caused by the exposure of the skin to chemicals that cause an allergic reaction such as poison ivy.
Contact Dermatitis
Pink, water-filled, raised lesions typically forming around the mouth in nose, that eventually rupture. Caused by staph infection.
Impetigo
Over-production of skin cells resulting in red epidermal lesions covered with dry, silvery scales. It is an autoimmune disorder in which the immune system attacks the body’s own tissues.
Psoriasis
Most common skin cancer. Skin can no longer produce keratin and the epidermis and dermis become separate.
Basal Cell Carcinoma
Another type of skin cancer caused by over sun-exposure.
Squamous Cell Carcinoma
Most rare type of skin cancer. Typically form where there are moles in the skin. It arises from accumulated DNA damage in a skin cell. Survival rate is 50%.
Malignant Melanoma
