front 1 What is the integument formed by? | back 1 skin, hair, nails, sweat and oil glands |
front 2 What are the layers of the skin? | back 2 Epidermis, dermis, and hypodermis |
front 3 What is the epidermis (stratum corneum) and what defenses does it provide? | back 3 - A thick layer of epithelial cells, packed w/ keratin giving the
cells the ability to withstand damage and abrasion.
- Lipids
are packed b/t cells giving them water-repelling properties
- It is replaced entirely every 25-45 days
- It contains a
basal layer which is the source for all the cells making up the
epidermis
|
front 4 What is the dermis and what defenses does it provide? | back 4 - Composed of connective tissue w/ a rich matrix of fibroblast
cells and fibers like collagen. It harbors a dense network of
nerves, blood vessels, and lymphatic vessels w/ damage causing the
dermis to bleed.
- Blisters form as a result of friction
trauma or burns, leading the dermis and epidermis to separate.
- Defenses include follicles, sweat gland, sebum, sweat, and
lysozyme
- Antimicrobial peptides are also a defense BUT they
are in both the dermis and epidermis
|
front 5 The defenses of the skin include: | back 5 - keratinized surface: creates water resistant barrier
- sloughing: continuous shedding of dead skin cells
- follicles: root of hairs containing sebaceous (oil) and scent
glands
- sweat glands: separate from follicles, producing sweat
w/ low pH and high salt concentration inhibiting microbes
- antimicrobial peptides: positive charged chemicals disrupt
negatively charged bacteria membranes
- sebum: secreted by
sebaceous gland creating low pH, high lipid concentration, and toxic
by-product via fatty acids breakdown
- lysozyme: enzyme in
sweat, tears and saliva that breaks down peptidoglycan
|
front 6 Which microbes make up the normal biota? | back 6 bacteria, viruses, archaea, fungi, and protists/protozoa |
| |
| back 8 raised lesion that is encapsulated and usually solid or semisolid |
| |
| back 18 - gram-positive coccus forming grape clusters, nonmotile and
sturdiest of all non-endospore forming to withstand high salt,
extremes in pH and high temps and viable after months of air
drying.
