| Question | Answer |
|---|---|
| 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 |
