Human Skin Anatomy Diagram - Layers, Hair Follicles & Blood Supply #1347573 (License: Personal Use)

This medical illustration depicts a 3D cross-section of human skin, clearly differentiating the epidermis (outer layer), dermis (middle layer with collagen and elastin), and hypodermis (subcutaneous fat). Visible structures include hair follicles with associated sebaceous and sweat glands, arrector pili muscles, arterioles (red), venules (blue), lymphatic vessels (yellow), and sensory nerve endings. The diagram emphasizes vascularization and innervation critical to thermoregulation, sensation, and nutrient delivery.

Used in dermatology textbooks, medical school curricula, health websites, and patient education materials to explain skin physiology, wound healing, or conditions like acne, alopecia, or eczema. Matches user intent for learning anatomy, understanding skincare science, or diagnosing cutaneous disorders.
