  1. The Integumentary System By: Nathan Mooney & Justin Franklin

  2. Skin • Made of several layers: -Epidermis -Dermis -Hypodermis • Allows for the growing of hair • With-holds many glands secreting sweat and oils (which are often by-products of other bodily functions)

  3. Hair • Consists of 3 main parts: -Follicle -Root -Shaft • Made of dead skin cells • Covers almost all of the body • Helps protect the body from UV damage • Traps warm air from exiting the skin, creating an isolation of sorts

  4. Nails • Made of 3 parts: -Root -Body -Free edge • Also made of dead skin cells • Grow from the “Nail Matrix” • Give structure to the ends of fingers and toes

  5. Sudoriferous Glands • Found in the dermis • Commonly known as the “Sweat Gland” • 2 different types -Eccrine glands: Secrete sweat straight to the surface of the skin -Apocrine glands: Send sweat to the surface via a duct

  6. Ingrown nails (Onychocryptosis) • Caused by the ridged cutting & regrowing of toe/finger nails • Most common on the big toe • Can be self-treated if found early enough • May lead to infection, and even require slight surgery

  7. Shingles (Herpes Zoster) • Comes from dormant chickenpox virus • Forms as a painful/blistering rash • Lasts for 2-4 weeks
