Integumentary System .....ANSWER..... · The skin is the heaviest
single organ of the body accounting for aprox 16% of body
weight.
· Composed of three layers: epidermis, dermis and the
subcutaneous tissues.
· Hair, nails, sebaceous and sweat glands are appendages of the
skin
Functions of the Skin .....ANSWER..... · Major function is to keep
the body in homeostasis.
,Page 2 of 93
· Provides protection from microorganisms, harmful substances &
radiation
· Thermoregulation
· Maintains fluid balance
· Immunity
· Absorption
· Excretion
· Synthesis of Vitamin D
· Sensation/communication with the external environment
Epidermis .....ANSWER..... · Most superficial layer of skin
· Thin avascular, relies on the underlying vascularized dermis for
nutrition
· Composed of stratified squamous epithelium (flat, dead cells
filled with keratin, helps make our skin waterproof)
,Page 3 of 93
· Composed of two layers: stratum corneum & stratum
basale/stratum spinosum
• The Stratum corneum is the outer horny layer composed of
dead keratinized cells.
• The inner cellular layer, is the stratum basale and the stratum
spinosum, also known as the malpighian layer, where both
melanin and keratin are formed. Migration from the inner to the
outer layer takes approximately 1 month."
Dermis .....ANSWER..... · 2nd layer, made up of richly
vascularized connective tissue
· Contains blood vessels, hair follicles and sensory nerves
· Supports and separates the epidermis from the subcutaneous
layer
· Dermal blood nourishes the epidermis
· Merges with adipose
, Page 4 of 93
· If you cut yourself and you notice that you are bleeding ten you
have got into the dermis layer
Subcutaneous tissue .....ANSWER..... · Hypodermis
· Composed of loose connective tissue filled with subcutaneous
(adipose cells, fatty cells)
· Functions: 1. connects the dermis to underlying organs 2.
generates heat and provides insulation 3. protective cushion 4.
provides (reserve for) calories
Skin Color .....ANSWER..... · Depends on the amount & type of
melanin (brownish pigment, genetically determined and increases
with exposure to sun)
· Also influenced by:
• Vascular structures
• Changing hemodynamics (ex: pallor due to anemia, cyanosis
due to hypoxia)
