Exam 4 Part 5

Question 1

Healing of wounds involving the epidermis:

Answer 1

Results is greater mitotic activity in the stratum basale & stratum spinosum

Question 2

Healing wound involving dermis/ or subcutaneous layer: Step 1

Answer 2

Wound causes rupture of blood vessels w/in the dermis (& subcutaneous layer if that deep) w/ resulting in bleeding

Question 3

Healing wound involving dermis/ or subcutaneous layer: Step 2

Answer 3

Blood platelets & fibrinogen proteins form a clot, which stops bleeding

Question 4

Healing wound involving dermis/ or subcutaneous layer: Step 3

Answer 4

Scab forms and seals off wound

Question 5

T/F Along w/ scab forming you may see signs of inflammation as damaged cells & foreign microorganisms are destroyed by immune cells

Answer 5

True

Question 6

Healing wound involving dermis/ or subcutaneous layer: Step 4

Answer 6

W/in dermis; fibroblasts form collagen fibers which binds wound edges together; w/in the epidermis, epithelial cells migrate in from wound edges & start proliferating

Question 7

Healing wound involving dermis/ or subcutaneous layer: Step 5

Answer 7

Scab sloughs off when healing is nearly complete

Question 8

• Injury of epidermis ONLY

- Skin becomes warm & reddened; surface layers of skin may be shed (peeling)

Answer 8

Frist degree burn

Question 9

• Deconstruction of epidermis & some underlying dermis as well (but NOT accessory organs)
• Skin blisters & healing process will involve epithelial cells from the accessory organs w/in the damaged area

Answer 9

Second degree burn

Question 10

With a second degree burn do you still have the hair follicle & exocrine ducts?

Answer 10

YES

Question 11

• Destroys the epidermis, dermis, & accessory organs

- Epithelial healing can occur ONLY at the margins of injury

Answer 11

Third degree burn

Question 12

• Destruction extends through ALL layers of the skin & perhaps into the underlying tissues
• Epithelial healing can occur ONLY at the margins of the injury

Answer 12

Answer 16

Question 17

Cutaneous carcinoma

Answer 17

Due to long term exposure to UVR; malignant

Question 18

Divisible into basal cell carcinoma & squamous cell carcinoma

Answer 18

Question 26

1) dietary deficiencies 2) Heavy metal exposure (hair & nails) 3) Allergic reactions (rashes/immune response) 4) Specific diseases (ex. iron deficiency anemia skin looks pale, Liver dysfunction Jaundice, yellowing of the skin & eye)

Answer 26

Integumentary system as a clinical indicator
