3. Organs in the Integumentary System
Skin
Epidermis- Outermost layer of the skin that forms barrier around the body
Dermis- Layer below the epidermis that contains blood vessels, hair follicles, and glands
Hair(3 layers)
Cuticle, cortex, and medulla

4. Organs in the Integumentary System
Nails
Hard layer of keratin
Glands
Sudoriferous glands- Eccrine and apocrine
Sebaceous glands- Found in every part of the skin except for palms and soles.
Ceruminous glands- found only in dermis of ear canals

6. Overall Functions of the Integumentary System
Protects you against exposure to dangerous things, repels water, minimises water loss, and protects underlying structures (blood vessels, nerves, and organs)
The skin regulates body temperature with its body supply
Sensory reception- Free nerve endings thought to be integrated with a variety of sensations including pain, heat, cold, and touch

7. Overall Functions of the Integumentary System
Sweat glands
The sebaceous glands are microscopic glands in the skin that secrete an oily/waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals

8. Individual Functions of the Organs
Skin
Epidermis - The epidermis provides a waterproof layer
Dermis - The dermis contains tissue which supports the skin, as well as providing energy and nutrition to the epidermis. It also plays an important role in thermoregulation and healing
Hypodermis - Supplies oxygen and nutrients to ALL layers of the skin. And it is also the layer of “ skin ” that anchors the skin to the body

9. Individual Functions of the Organs
Hair
Insulates the body, protects the surface of skin, serves as a friction buffer, and it also redirects water and sweat
Nails
Made out of hardened keratin, they protect our delicate nail beds

11. Function of Individual Cells, Enzymes, or Hormones if Pertinent
Apocrine - Triggered by emotional stress, it is 1 of 2 types of sweat glands, it mostly composes of fatty sweat
Eccrine - Also triggered by emotional stress, they release sweat mostly composed of water and salt

12. How Does it Interact: Nervous System
The integumentary system interacts with the nervous system in many different ways. One major way is that the nervous system relies greatly on neurons that are imbedded in your skin to receive information about the outside world. For example, if you stub your toe or it is cold outside, the neurons in your skin are going to let your body know to increase your body temperature or send pain signals to your toe.

14. How does it interact: Muscular system
The integumentary system also greatly interacts with the muscular system. Skin protects every little muscle in your body from the very dangerous outside world. By maintaining the right amount of pressure, the right temperature, and controlling what comes into the body, your skin protects those muscles that help you move around.
