integumentary | largest organ of the body otherwise known as skin |
epidermis | stratified squamous with keratin layer, sweat pores & hair shafts |
dermis | layer of skin just below the epidermis that contains sweat, sebaceous glands as well as nerves, blood vessels and hair follicles |
hypodermis | bottom layer of skin; fatty layer, arterioles & venules found here |
sebaceous glands | oil glands found in dermal layer of skin |
cutaneous membrane | waterproof & protective membrane found on skin |
mucus membrane | lines the body cavities that open to the exterior; protective; lubricating secretions |
serous membrane | lines cavities closed to exterior (except joints); protection, fluid allows membranes to slide over each other |
synovial membrane | lines fibrous capsules lining joints; cushions organs as they move against each other |
anagen | mature hair follicle; growth phase |
catagen | transitional stage of hair follicle between growth & resting (falling out) stage |
telogen | "resting stage" of hair follicle; hair eventually falls out from this stage |
epithelial cells | cell that line the cavities of the body |
squamous epithelial cells | tile shaped epithelial cells found in alveoli & capillaries |
cuboidal epithelial cells | cube shaped epithelial cells; gland and their ducts; forms the walls of kidneys & ovaries |
columnar epithelial cells | tall, column shaped epithelial cells; goblet cells (produce lubricating mucus); line the length of the digestive system from stomach to anus |
stratified epithelial cells | 2 or more layers of epithelial cells; provides a more durable layer |
1st degree burn | skin is red and irritated; epidermis only affected |
2nd degree burn | affected area dips to dermal layer; blistering may occur; scarring may occur |
3rd degree burn | nerve damage; may be no pain due to severe nerve damage at site of burn; grafts usually required; scars usually result |
malignant | cancerous |
benign | noncancerous |
