This educational illustration depicts a vertical cross-section of human skin, highlighting the epidermis (outer protective layer), dermis (middle layer with collagen, elastin, hair follicles, sweat glands, and sensory nerves), and hypodermis (subcutaneous adipose tissue). Key anatomical features such as hair bulbs, sebaceous glands, arrector pili muscles, and vascular networks are clearly labeled to support learning in anatomy and physiology contexts.

Used in K-12 science curricula, medical training materials, dermatology websites, and health education resources to teach skin structure and function; matches user intent for visual learning, study aids, or classroom handouts.
