The Integumentary System By: Nathan Mooney & Justin Franklin
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)
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
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
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
Ingrown Nails (Onychocryptosis) • Caused by the ridged cutting & regrowing of toe/finger nails • Possible symptoms: -Ridged cutting of nails -Nails growing into/through the surface of the skin • Most common on the big toe • Can be self-treated if found early enough • May lead to infection, and even require slight surgery
Shingles (Herpes Zoster) • Comes from dormant chickenpox virus. • Possible symptoms: -Headache -Dizziness -Sensitivity to light -Irritated skin • Forms as a painful/blistering rash • Lasts for 2-4 weeks
Relationship with the Nervous System • Much of the nervous system’s receptors reside within the skin, allowing for it to take in lots of data on external conditions, such as temperature, pressure, or dangers. • With this information, the body is able to balance its-self accordingly and maintain homeostasis.
Relationship with the Excretory System • While sweating, not only are you cooling down your body, youre also ridding of tiny amounts of waste with each drop.
