When the wrist extends back (dorsiflexion), the fingers automatically want to curl (tenodesis action). When the wrist flexes forward, the fingers extend. This is passive tension. A figure with a hyper-extended wrist and straight fingers is biomechanically screaming.
Muscles don't just change size; they change shape, bunching up near the joint and thinning out at the attachments. When the wrist extends back (dorsiflexion), the fingers
: Knuckles are not aligned in a straight line; they form a distinct arc. When the fingers flex, these bony landmarks become prominent, creating sharp planes that catch light and cast shadows. Key Takeaways for 3D Artists and Sculptors A figure with a hyper-extended wrist and straight
Anatomy does not stop at the joint. To sculpt a realistic arm in motion, you must understand the shoulder girdle—comprising the clavicle, scapula, and humerus. [Clavicle] <---> [Scapula] \ / [Humerus (Arm)] When the fingers flex, these bony landmarks become
