Hand Anatomy Illustration: Open Palm vs. Closed Fist Gesture #69478 (License: Personal Use)

This black-and-white line illustration depicts two contrasting hand positions: on the left, a fully extended palm with realistic skin folds, cuticle details, and fingernail contours; on the right, a forceful fist with fingers curled inward, thumb secured across the index and middle fingers, highlighting joint compression and muscle engagement. The clean, clinical style makes it suitable for educational diagrams in anatomy, physiotherapy, or gesture-based communication guides.

Used in medical textbooks, occupational therapy materials, ASL learning resources, or ergonomic design documentation to demonstrate hand mobility, grip mechanics, or aging-related skin changes. Matches user intent for visual reference in health, education, or accessibility contexts.
