Study Notes
Skin Structure
- Thick (non-hairy) skin is primarily found on the palms of the hands and soles of the feet.
- The epidermis has a histological structure composed of several layers of cells, with the outermost layer being the stratified squamous epithelium.
Subcutaneous Tissue
- The hypodermis is located beneath the dermis, and is also known as subcutaneous tissue.
Cell Structure
- The nucleus is the control center of a cell, responsible for storing genetic information.
- A mononucleated cell has one nucleus.
- An example of a binucleated cell is a hepatocyte, a type of liver cell.
- The nucleus is basophilic, meaning it stains blue with basic dyes.
- The nucleus tends to occupy a central position within the cell, often surrounded by cytoplasm.

Description
Test your knowledge of human skin anatomy with this quiz. Identify and understand the different types of skin, including thick (non-hairy) skin found in specific areas and thin (hairy) skin covering the rest of the body. Explore the histological structure of the epidermis and dermis, and learn about the hypodermis as the subcutaneous connective tissue fascia under the dermis.
