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

papilla
alopecia

10. Glands of the Skin sudoriferous sebaceous ceruminous glands
sweat glands
cool the body
sebaceous
sebum(oil)
ceruminous glands
modified sweat glands located in ear canals
cerumen

11. Nails
cuticle
lunula

12. Breasts or Mammary Glands
Present in both males and females
estrogen stimulation causes adipose tissue and increased size
progesterone stimulation causes formation of lobules for milk production

involves epidermis and dermis
can extend into subcutaneous tissue, bone and muscle
cannot heal spontaneously
