2. INTEGUMENTARY SYSTEM
Correct Pronunciation (in-teg-you-MEN-tah-ree)
Forms a protective two-way barrier around
the entire body and aids in temperature
regulation.
Made up of 5 structures: the SKIN
organ, hair, nails, sweat glands, and
sebaceous glands.
3. THE SKIN ORGAN
The major organ of the
integumentary system,
forming a barrier
between the external &
internal environments.
Top layer of skin made
of epithelium tissue,
which are composed of
close-packed cells that
form a covering.
4. THE MAKE UP OF SKIN
There are three layers
Epidermis- thin, outer
membrane layer.
Dermis- middle, fibrous
connective tissue layer.
Subcutaneous-
innermost layer
containing fatty tissue.
Dermatology (der-mah-TALL-oh-
jee)- is the study of skin &
the integumentary
system.
5. THE BREAK DOWN- EPIDERMIS
Epidermis- consist of a type
of epithelial tissue called
stratified squamous
epithelium, which is free of
blood and depends on
deeper layers for
nourishment.
Basal layer-deepest layer of
the epidermis, which forms stratified squamous epithelium
new cells that push old cells
to the top.
Melanin- contained in the
basal layer and produces a
Black pigment that is
responsible for the coloring
of skin and also protects
against ultraviolet rays of the
sun.
6. THE BREAK DOWN- DERMIS
Dermis- middle layer of
skin with a very good
blood supply -“true skin”.
Collagen Fibers- glue-
like protein contained
within the dermis and
gives connective tissues
its strength.
Dermis houses…
Hair follicles
Sweat glands
Blood vessels
Nerve fibers
Muscle fibers
And other elements
7. THE BREAK DOWN- SUBCUTANEOUS
Subcutaneous- also
called “hypodermis”, is
the deepest level of
skin and composed of
fat cells called
lipocytes.
Lipocytes- protects the
deeper tissues of the
body & acts as
insulation from heat and
cold.
8. ACCESSORY ORGANS & SKIN DISORDERS
Accessory Organs of the SKIN- are the
anatomical structures within the dermis such as
hair, nails, sebaceous glands and sweat glands.
Some skin disorders are rosacea, eczema, and
strawberry hemangioma. All of which can be
managed by help from a dermatologist.
Lets all protect our skin by keeping it
clean, properly moisturized and protected
from extreme heat or cold at all times.
