A highly detailed, anatomically accurate 3D model of the complete male muscular system. Static, in a standard anatomical pose (e.g., T-pose or relaxed A-pose). All superficial and deep muscle groups must be clearly visible and well-defined, showcasing realistic muscle texture, striations, origins, and insertions. Render with neutral, even lighting suitable for anatomical study. No animation required. Focus on scientific accuracy and high fidelity for educational or reference purposes.
