Hair Follicle Anatomy Diagram - Structure and Function Explained #259676 (License: Personal Use)

This black-and-white medical illustration depicts a vertical cross-section of a human hair follicle embedded in the dermis and epidermis. Visible components include the hair shaft emerging at the surface, the hair bulb with dermal papilla, sebaceous glands secreting sebum, the arrector pili muscle responsible for goosebumps, and surrounding connective tissue and fat cells. The diagram clarifies how follicular structures interact to support hair growth, thermoregulation, and skin protection.
