| Question | Answer |
|---|---|
| Epithelial membrane | composed of epithelial tissue and an underlying layer of specialized connective tissue |
| Connective tissue membrane, or Glossary synovial membrane, | example of connective tissue membrane, and it is found lining the spaces between joints and bones. |
| serous membrane | only on surfaces within closed cavities |
| lamina propria | located in underlying mucous membrane |
| membranes | Thin, sheetlike structures that cover and protect the body surface |
| two major types of body membranes | epithelial, connective tissue |
| peritonitis | Inflammation of the serous membrane in the abdominal cavity |
| parietal pleura | serous membrane that lines the thoracic cavity |
| mucous membrane | Epithelial membranes that line body surfaces opening directly to the exterior |
| keratin | tough, waterproof material that protects the outer layer of the skin |
| melanin | The basic determinant of skin color |
| synovial membranes function | line joint capsules, secretes lubricant fluid, line small sacs(bursae) |
| dermal papillae | upper region of the dermis is characterized by parallel rows of tiny bumps |
| lanugo | hair of a newborn infant is soft and fine |
| Sweat glands Classification | eccrine, apocrine |
| functions of the skin | protection, sense organ activities, temperature regulation, excreation |
| sebum | secretion from hair follicles that helps lubricate the hair and skin |
| subcutaneous Tissue (hypodermis) function | insulation of extreme temperature, source of stored energy, shock absorber for underlying tissue |
| Superficial fascia | name for hypodermis by Anatomists |
| arrector pilli | structure that causes "Goose pimples” |
| Epidermis, Dermis | skin layers of tissue |
| stratum germinativum | tough keratinized layer of the skin |
| eccrine sweat glands | most numerous, important, widespread in the body |
| apocrine sweat glands | found under armpit (axilla) and pigmented skin areas around genitals. |
| serous membrane structure | 2 layers, simple squamous epithelium, connective tissue layer, gluelike basement membrane |
| cutaneous membrane (skin) | has superficial layer of epithelial cells and underlying layer of supportive connective tissue |
| pleura | serous membrane for thoracic cavity |
| peritoneum | serous membrane for abdominal cavity |
| parietal layer | forms lining of body cavity |
| visceral layer | covers the organs found in cavities |
| epidermis | skin structure thin sheet of stratified squamous epithelium |
| dermis | deeper layer; largely connective tissue |
| pigment layer | stratum germinativum, pigment production Melanin, melanocytes |
| Nails structure | Nail bed, nail body, cuticle, Lunula, free edge |
| vitiligo | patchy areas of light skin, loss of epidermal melanocytes |
| reticular layer | deeper area of dermis, filled with a dense network of interlacing fibers, |
| subcutaneous tissue | hypodermis; not layer of skin, loose fibrous and adipose tissue. |
| birthmarks | (pigmented) developmental malformation of dermal blood |
| birthmark type | strawberry hemangioma, port-wine stain, stork bite. |
| hair follicle | epidermal tubelike structure , required for hair growth |
| hair papilla | hair growth starts here |
| hair root | hidden in follicle |
| shaft | visible part of hair |
| Fingerprint | Dermal papillae |
| Follicle | Hair |
| Tinea | fungal infection |
| Little moon | Lunula |
| Keratin | waterproofing |
| Sebaceous glands | secrete oil or sebum, for hair and skin |
| Pleura | Epithelial membrane |
| Perspiration | Sudoriferous sweat glands |
| common type of skin cancer | squamous cell carcinoma, Basal carcinoma, Melanoma |
| squamous cell carcinoma | most common; characterized by hard, raised tumors |
| Basal carcinoma | characterized by papuls with a central crater; rarely spreads |
| Melanoma | malignacy in a nevus, mole most serious skin cancer |
| lamina propria | fibrous connective tissue beneath the epithelium in mucous membrane |
| arrator pili | goose bumps |
| Stratum corneum | also known as outer epidermis. Tough keratinized |
| dermal papillae | upper dermis layer Finger prints |
| Epidermis layer | stratum basale; Spinosum; Granulosum; Lucidum |
| Stratum Basale | also Stratum germinativum; growth layer |
| Stratum granulosum | Epidermis granular layer |
| Stratum lucidum | Epidermis clear layer |
| Stratum corneum | referred to as the "barrier area" and is the most superficial layer of epidermis) |
| superficial | being at, on, or near the surface: |
| papillary layer | forms bumps, called Dermal papillae, that project into the epidermis |
| reticular layer | contains dense, interlacing collagenous and elastic fibers that make the skin tough, yet stretchable. |
| Sudoriferous | Perspiration |
| Dermis & epidermis | mayor layer of skin |
| where to find Keratin at skin | outer layer |
| Acne, scab, warts, non genital herpes vesicles | elevated Lesion |
| freckle, vitiligo, | flat lesion |
| striae, bedsore, athlete foot, scratch | depressed lesion |
| Birthmark | malformation of dermal blood vessels |
| Scleroderma | hard skin |
| urticaria | another name for hives |
| Synovial membrane | type of connective tissue membrane |
| Serous membrane | found in closed body cavities |
| parietal layer | lines the walls of body cavities, much like wallpaper. |
| visceral layer | covers the surfaces of organs found in body cavities. |
