Skin
Cutaneous Membrane – Skin, Epidermis,
Dermis, Subcutaneous Layer
Facts about Skin
•
•
•
•
Largest organ in the body.
Surface area of 18 sq. ft., weighs 6-10 lbs.
3000 sq inches of surface area.
About 15% of total body weight.
Layers of the Skin
• Epidermis – “Horny
Layer”
– Outermost layer
– semi-permeable
– 5 Layers :
• Two main Layers:
Stratum Corneum
• Stratum Germinativum
Skin Layers
• Dermis: “True Skin”
– Corium
– Elastic connective tissue
– Contains blood vessels, lymph vessels, nerves,
involuntary muscle, sweat and oil glands, and hair
follicles.
– The top layer is papillae, fit into the layers of the
stratum germinativum of the epidermis
• Forms fingerprints
Skin Layers
• Subcutaneous Fascia
“Hypodermis”- the
innermost layer.
– Elastic and fibrous
connective tissue and
adipose tissue.
– Connects the skin to
underlying muscles.
Functions of the Skin
Protection :
• Serves as barrier UV light, pathogens, and
germs.
• Holds moisture in and prevents deeper tissues
from drying out.
Sensory Perception:
• Nerves in the skin help the body respond.
Functions of the Skin
Body Temperature Regulation:
• Blood vessels
• Sudoriferous glands cool by sweating and
evaporation.
Storage:
• Skin has tissues for temporary storage of fat,
glucose, water, vitamins, and salts.
• Adipose is a source of energy.
Functions of the Skin
Absorption:
• Medications
Excretion:
• Eliminates salt, small amount of waste, excess
water and heat.
Production:
• Production of Vit D using UV light.
Pigmentation
Melanin - cells that create brown color
Carotin - Orange pigmentation
Blood - pink pigmentation
