2. Key Concepts

3. Where is skin found? Skin is found throughout the body,
Your skin is made up of epithelial cells.
There are 3 types of epithelial cells:

9. Structure of the skin
Thickest
Thinnest
Layers of the skin: 1. 2. 3. 3

10. 4

11. 1. Epidermis Protects the body against
Epidermis is made up of 5 layers: a. b. c. d. e.

12. 2. Dermis Composed of fibrous connective tissue .
Dermal blood vessels are important for

13. Hypodermis (aka subcutaneous)
Made up of adipose (fatty) tissue
Functions:

14. Glands of the skin
Three types of integumentary glands 1. 2. 3.

15. 1. Sebaceous glands (oil glands)
Functions: 24

16. 2. Sudoriferous Glands (sweat glands)
Two types:
Apocrine glands:
Eccrine glands:

18. 3. Ceruminous Glands
Specialized sweat glands found in the ear canal .

19. Injuries to the skin: burns
Can be fatal, disfiguring, or incapacitating .
3rd largest cause of accidental death

20. Burn Injuries Complications.

21. Burn Classifications
1st degree (Superficial burn)

22. Burn Classifications
2nd degree (partial thickness burn)

23. 3rd degree (full thickness burn)
Burn Classifications
3rd degree (full thickness burn)

24. Skin Cancer
The three major types of skin cancer are: 1. 2. 3.

25. Basal Cell Carcinoma .

26. 2. Squamous Cell Carcinoma

27. 3. Melanoma .

28. Skin Color Skin color results from three different pigments:
1. Hemoglobin:
2. Carotene:
3. Melanin: 13
