2. 1. Describe the structure of the skin
2. Summarize the factors that determine skin color
3. Describe the accessory structures associated with the skin
4. Explain the functions of each accessory structure of the skin
5. List various skin functions, and explain how the skin helps
regulate body temperature
6. Summarize life-span changes in the integumentary system
LEARNING OBJECTIVE

3. • The skin is the biggest organ in the body
• Main function as the body containment and protection
• Made up of multiple layers of ectodermal tissue
• The thickness of skin very much varies from bodily location to
location

9. •Dermal papillae → Fingerprint
•Muscle fibers
• Smooth muscle
• Skeletal muscle
•Blood vessels for
thermoregulation
•Nervous System
• Motor nerve cell
• Sensory nerve cell → Sensation

DERMIS

10. •Nails
• Origin: Epidermis
• Protection
•Hair follicles
• Hair loss: 100 hairs a day
• Eumelanin → brownish-black
• Pheomelanin → reddish-yellow
• M. erector pili → goose bumps
• Associated with sebaceous
glands
