Previous problemNext problem

Verified step by step guidance

Understand the anatomy of the hair structure: The hair is composed of several parts including the hair shaft, hair follicle, sebaceous gland, and arrector pili muscle.

Identify the function of each structure: The hair shaft is the visible part of the hair, the sebaceous gland produces sebum, the arrector pili muscle is responsible for making the hair stand up, and the hair follicle is the structure from which the hair grows.

Focus on the hair follicle: The hair follicle is a complex structure that includes different regions such as the bulb, bulge, and papilla.

Learn about the hair follicle bulge: The bulge is a specific region of the hair follicle that serves as a niche for stem cells. These stem cells are crucial for hair regeneration and repair.

Conclude that the hair follicle bulge is the correct answer: Based on the understanding of the hair follicle anatomy and the role of stem cells, the bulge is the part of the hair structure that stores stem cells.
