Lesson 3.1
Body Membranes

4. Body Membranes epithelial membranes connective tissue membranes
mucous membranes
serous membranes
cutaneous membranes
connective tissue membranes
synovial membranes

5. Epithelial Membranes mucous membranes serous membranes
line cavities open to the environment
serous membranes
line cavities not open to environment
cutaneous membranes
form what we know as skin

6. Mucous Membranes and Serous Membranes

7. Connective Tissue Membranes
synovial membrane
capsule around synovial joint
tendon sheath
synovial fluid

8. Review and Assessment
Match these words with 1–4 below: synovial, mucous, cutaneous, serous. 1. line cavities open to the environment 2. line cavities not open to the environment 3. tendon sheath 4. form skin

The Integumentary System

10. The Integumentary System
functions of the integumentary system
anatomy of the skin
appendages of the skin

11. Functions of the Integumentary System
protects against
abrasion
chemical damage
drying out
UV radiation damage
regulates body temperature

12. Functions of the Integumentary System

13. Anatomy of the Skin
epidermis
dermis
hypodermis

14. Layers of the Epidermis

15. Review and Assessment True or False?
1. The dermis is the superficial layer of the skin.
2. The skin helps regulate body temperature.
3. The epidermis has three layers.
4. The hypodermis is above the dermis.
5. The skin protects against UV radiation.

16. Epidermal Cells keratinocytes epidermal dendritic cells Merkel cells
produce keratin, form layers of epidermis
epidermal dendritic cells
ward off infections
Merkel cells
touch receptors

17. Dermis dense, fibrous connective tissue papillary layer
forms fingerprints
reticular layer

18. Hypodermis fibrous connective tissue adipose tissue padding insulation
energy storage

19. Appendages of the Skin sudoriferous (sweat) glands sebaceous glands
eccrine
apocrine
sebaceous glands
hair
nails
