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
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

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
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
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
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
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

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.
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.
