Functional Human Anatomy, a free science course on Tomo

Functional Human Anatomy

Understand how the human body balances mobility, stability, and internal pressure during movement. Learn why joint pain often originates several segments away, how fascial sheets distribute kinetic load, and how anatomical bottlenecks protect critical nerves and vessels.

Like Duolingo, but for Functional Human Anatomy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Movement Mechanics and Force Transfer and Internal Pressures and Structural Passages. It assumes you already know the basics.

What you'll learn

Key ideas in Functional Human Anatomy

  • The kinetic chain alternates stacked mobility and stability segments from foot to head.
  • The knee (tibiofemoral) and scapulothoracic joints are built primarily to restrict excessive planar movement.
  • The hip (coxofemoral) and ankle (talocrural) joints require multi-axis freedom of movement.
  • The knee is a hinge joint meant for sagittal flexion, poorly built to handle torque and shear.
  • When a mobile joint loses range, the neighboring stable joint moves out of its primary plane.
  • Restricted ankle dorsiflexion forces the adjacent knee to compensate by collapsing into valgus.
  • Anterior pelvic tilt increases lumbar lordosis and compresses the posterior aspect of lumbar discs.
  • Posterior pelvic tilt flattens the lumbar curve, increasing anterior disc compression and flexion shear.
  • Neutral pelvic alignment optimizes the spine's natural curves to distribute vertical loads evenly.
  • Feedforward motor control fires deep stabilizing muscles milliseconds prior to prime mover activation.
  • The transverse abdominis and multifidus tense the thoracolumbar fascia before limb movement begins.
  • Reactive muscle stiffening that occurs after movement starts arrives too late to prevent joint shearing.
  • Apparent leg length discrepancy often stems from asymmetrical tonicity in the quadratus lumborum.
  • Unilateral gluteus medius weakness causes dynamic lateral pelvic drop (Trendelenburg sign).
  • Functional pelvic misalignments disappear when unloaded, whereas true structural bone discrepancies persist.
  • Fascial sheaths link distant muscles into uninterrupted longitudinal tracks across multiple joints.
