front 1 List the two layers of skin and briefly describe subcutaneous tissue. | back 1 Epidermis - composed of epithelial cells, is the outermost protective shield of the body. Dermis - the only vascularized layer making up the bulk of the skin, is tough, leathery layer composed mostly of dense connective tissue. Subcutaneous tissue > Hypodermis (superficial fascia)
|
front 2 The epidermis is composed of which of the following tissues? | back 2 Keratinized stratified squamous epithelial tissue |
front 3 Which layer of the skin- dermis or epidermis- is better nourished? | back 3 The Dermis
|
front 4 Which Cell makes up most of the Epidermis and it's chief role is to produce keratin, the fibrous protein that helps give the epidermis it protective properties?
| back 4 A |
front 5 Which Cell of the Epidermis is a spider-shaped epithelial cell that synthesizes the pigment melanin?
| back 5 B |
front 6 Which star shaped Cell of the Epidermis, also known as a Langerhans cell, arise from bone marrow and migrate to the epidermis where they ingest foreign substance and are key activator of our immune system.
| back 6 C |
front 7 Which spiky hemisphere shaped Cell of the Epidermis, also known as a Merkel, occasionally are present at the epidermaldermal junction and functuions as a sensory receptor for touch.
| back 7 D |
front 8 While walking barefoot in a barn, Jeremy stepped on a rusty nail that penetrated the epidermis on the sole of his foot. Name the layers the nail pierced from the superficial skin surface to the junction with the dermis.
| back 8 C |
front 9 Most Superficial layer; 20-30 layers of dead cells, essentially flat membranous sacs filled with keratin. Glycolipids in extracellular space.
| back 9 A |
front 10 Typically one to five layers of flattened cells, organelles deteriorating; cytoplasm full of lamellar granules (release lipids) and keratohyaline granules
| back 10 C |
front 11 Several layers of keratinocytes unified by desmosomes. Cells contain thick bundles of intermediate filaments made of pre-keratin.
| back 11 D |
front 12 Deepest epidermal layer; one row of actively mitotic stem cells; some newly formed cells become part of the more superficial layers. See occasional melanocytes and dendritic cells.
| back 12 E |
front 13 Layer of epidermal tissue that is only found in thick skin and subject to abrasion. ie: palms, fingertips, and the soles of the feet
| back 13 B |
front 14 The stratum basale is also called the stratum germinativum, a name that refers to its major function. What is that function? | back 14 the stratum basale undergoes almost continuous mitosis to replace cells lost by abrasion. |
front 15 Why are the desmosomes connecting the keratinocytes so important? | back 15 The skin is subject to a lot of abrasion and physical trauma. The desmosomes, which are connecting junctions, help to hold the cells together during such stress. |
front 16 Which of the following structures are primarily responsible for fingerprints?
| back 16 D |
front 17 Name the tissue type/s composing the dermis. | back 17
|
front 18 Which layer of the dermis is responsible for producing fingerprint patterns?
