Electrolysis Practice Exam

Which of the following is not considered an appendage of the skin?

1. Hair

2. Nails

3. Sweat glands

4. Capillaries

The correct answer is: Capillaries

The correct answer is that capillaries are not considered appendages of the skin. In terms of skin structure, appendages refer to specialized structures that develop from the skin itself, such as hair, nails, and sweat glands. These structures serve specific functions but are distinct from the main skin layer. Capillaries, on the other hand, are tiny blood vessels that are part of the circulatory system. While they are found in the dermal layer of the skin and play a crucial role in supplying blood, delivering nutrients, and regulating temperature, they do not originate from the skin. Instead, they are components of the vascular system and are not classified as skin appendages.
