Identify the part of the hair that is visible above the skin's surface, which is known as the 'shaft'.
Determine the part of the hair that is located below the skin's surface, within the dermis, called the 'root'.
Recognize that the root is embedded in a structure known as the 'hair follicle'.
Understand that the area of the hair where cells actively divide and undergo mitosis during the growth phase is called the 'hair matrix'.
Combine these terms to fill in the blanks: The portion of the hair that projects from the surface of the skin is the 'shaft', and the portion within the dermis is the 'root', which is embedded in a 'hair follicle'. The portion of the hair that contains cells that undergo mitosis during the growth stage of the hair is known as the 'hair matrix'.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Hair Structure
Hair is composed of two main parts: the hair shaft, which is the visible portion that extends above the skin's surface, and the hair root, which is located beneath the skin in the dermis. Understanding this structure is essential for answering questions about hair anatomy and its functions.
The dermis is the layer of skin beneath the epidermis that contains connective tissue, blood vessels, and hair follicles. It plays a crucial role in supporting hair growth and providing nutrients to the hair root, making it important for understanding hair development.
The hair follicle is a small, tubular structure in the dermis that houses the hair root and is responsible for hair growth. It contains cells that undergo mitosis, leading to the formation of new hair cells during the growth phase, which is vital for understanding hair biology.
