- The color of blood in the dermis contributes to skin color.
- The color of blood in the dermis contributes to skin color.
A decrease in blood flow, as occurs in shock, can make the skin appear
pale
A decrease in the blood O2 content produces a bluish color of the skin, called
Cyanosis
- Most common cancer
Skin cancer
Mainly causes by UV light exposure
Skin cancer
more prone to cancer
Fair-skinned people
- rays cause tan and is associated with malignant melanomas

The skin (cutaneous membrane) rests on the
- subcutaneous tissue
The subcutaneous tissue, which is not part of the skin, is sometimes called
Hypodermis
The subcutaneous tissue attaches the skin to underlying bone and muscle and supplies it with
blood vessels and nerves
It is loose connective tissue, including adipose tissue that contains about half the body’s stored
lipids
The amount and location of adipose tissue vary with
age, sex and diet
Adipose tissue in the subcutaneous tissue functions as
padding and insulation
The subcutaneous tissue can be used to estimate
total body fat
The acceptance percentage of body fat females
21%-30%
The acceptance percentage of body fat males
- 13% to 25% for males.
Each hair arises from a
hair follicle
- an invagination of the epidermis that extends deep into the dermis.
hair follicle
protrudes above the surface of the skin;
hair shaft
