Human Arm Anatomy Diagram - Extended Position Illustration #111269 (License: Personal Use)

This black-and-white line illustration depicts a human arm fully extended horizontally from the shoulder, elbow straightened, wrist neutral, and fingers gently splayed. The clean, unshaded style emphasizes skeletal alignment and joint positioning without anatomical detail, making it suitable for instructional or schematic use. It avoids muscle or skin texture to focus purely on form and orientation.

Commonly used in educational materials (e.g., anatomy textbooks, physiotherapy guides), ergonomic assessments, gesture recognition tutorials, or UI/UX design references for hand interaction patterns. Matches user intent for visualizing neutral arm extension in medical, design, or motion studies contexts.
