Anatomy of the Arm: Muscular Structure Illustration #14145 (License: Personal Use)

This black-and-white line drawing depicts a human arm in mid-flexion, with pronounced biceps brachii, brachialis, and forearm flexor muscles visible beneath the skin. The hand is clenched into a fist, illustrating the engagement of intrinsic hand muscles and tendon tension. The stylized yet accurate representation supports educational use in physiology, kinesiology, or strength training contexts.

Used on anatomy learning pages, fitness guides, physical therapy resources, or workout tutorials where visualizing muscle activation during elbow flexion or gripping is essential; matches user intent to understand arm biomechanics or improve exercise form.
