  terms and procedures related to the integumentary
  system.

4
Functions of the Integumentary System

• skin
• protects against bacterial invasion
• reservoir for food and water
• sensory receptor
• synthesis of vitamin D
• regulate body temperature and water
• prevents dehydration

5
Epidermis

• outermost layer
• epithelium
• strata or layers
• keratin (a fibrous protein)
• no blood vessels or nerve supply in epidermis

6
Dermis or Corium

• Living Tissue
• capillaries
• lymphatics
• nerve endings
• hair follicles
• glands (sebaceous and sweat)

7
Subcutaneous or Hypodermis

• connective tissue layer
• specializes in formation of fat
• adipose or fat cells provide a food reserve and
  insulation

11
Nails

• cuticle

12
Breasts or Mammary Glands

• Present in both males and females

  increased size

17
Burns-First DegreeSuperficial

• Outer Layer of Epidermis
• erythema
• hyperesthesia
• Example Sunburn

18
Burns-Second DegreePartial Thickness

• damages portion of epidermis and dermis
• vesicles or bullae
