Human Muscle Anatomy
Discover how facial expressions, posture, and athletic movements actually work from the inside out. Learn the major muscle groups of the human body and the physiological mechanics behind every motion.
Like Duolingo, but for Human Muscle Anatomy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 3 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through The Expressive Face and Head, The Torso and Upper Limbs, and The Lower Body and Muscle Physiology. It starts from scratch.

Key ideas in Human Muscle Anatomy
- Limb and torso muscles pull bone against bone across joints to move limbs
- Facial muscles anchor directly into the dermal skin layer
- Pulling skin instead of joints enables nuanced surface wrinkles, ripples, and expressions
- Orbicularis muscles are ring-shaped muscles acting like circular drawstrings
- Orbicularis oculi loops around each eye socket to blink, close eyelids, or squint
- Orbicularis oris loops around the mouth opening to compress and purse the lips
- The zygomaticus major originates on the cheekbone and inserts into the mouth corner
- Contracting it pulls the corners of the mouth diagonally upward and outward
- This upward lift creates the classic smile shape and bunches the cheeks
- The frontalis covers the forehead and pulls the eyebrows upward to convey surprise or curiosity
- The corrugator supercilii draws the brows inward and downward, creating vertical worry lines between the eyes
- Raising the brow opposes the furrowing action of the corrugator
- Stress habitually clenches the jaw elevators and knots the muscles between the eyebrows
- Allowing the lower jaw to unclamp with lips resting softly releases the jaw muscles
- Consciously softening the space between the brows releases the corrugators
- Clenching your teeth causes the masseter to bulge at the corner of your lower jaw
