Functional Human Anatomy, a free science course on Tomo

Functional Human Anatomy

Understand how the human body operates as an integrated mechanical and physiological system. Explore joint levers, vascular pressure gradients, organ compartmentalization, and deep neural wiring.

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.

24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Mechanics of Movement and Load; Pressure, Flow, and Gas Exchange; Visceral Architecture and Internal Crossroads; and Control Networks and Structural Routing. It assumes you already know the basics.

What you'll learn

Key ideas in Functional Human Anatomy

  • In a third-class lever, the effort inserts between the joint fulcrum and the load.
  • Third-class levers require more muscle tension than load weight but amplify distal speed.
  • Small muscle contractions produce large, rapid excursions of the hand or foot.
  • Deep bony sockets increase joint stability but physically restrict angular mobility.
  • Shallow fossae grant extreme range of motion by relying on vulnerable soft tissues.
  • Capsular tightness and ligamentous check-reins trade motion freedom for dislocation resistance.
  • Pennate fibers attach obliquely to a central tendon, packing more cross-sectional area into a volume.
  • Higher physiological cross-sectional area dramatically increases peak contractile tension.
  • Angled muscle fibers shorten over a shorter total excursion distance than parallel fibers.
  • Antagonists fire eccentrically at end-range to brake limb momentum and protect ligaments.
  • Co-contraction increases joint compressive forces to center the articulating bones.
  • Antagonists act as dynamic stabilizers rather than passive or completely relaxed opponents.
  • Open-chain movements isolate motion to one joint, generating substantial linear shear stress.
  • Closed-chain movements fix the distal end, transmitting axial compression across multiple joints.
  • Multi-joint closed chains recruit surrounding co-contractors that cushion individual capsules.
  • Deep investing fascia forms a continuous fibrous network rather than isolating individual muscles.

Questions

Questions about Functional Human Anatomy

  1. How do I learn Functional Human Anatomy?

    Go in order: start with Mechanics of Movement and Load, then Pressure, Flow, and Gas Exchange, then Visceral Architecture and Internal Crossroads, then Control Networks and Structural Routing. On Tomo that's 24 short levels, about 48 minutes in all, played five minutes a day. Start free and play the first level in under a minute.

  2. Is there a Duolingo-style app for Functional Human Anatomy?

    Yes. Tomo works like Duolingo: short daily lessons, streaks and quick quizzes. Functional Human Anatomy is one of its free courses, and you can type any other topic to get a course of your own.

  3. Is the Functional Human Anatomy course free?

    Yes. Functional Human Anatomy is playable on Tomo's free plan, which doesn't expire. No credit card, no waitlist. Download the app and start your first lesson.

  4. How long does it take to learn Functional Human Anatomy?

    24 levels across 4 sections, about 48 minutes of play in total. It's built for five minutes a day, so you finish it a little at a time instead of all at once.

  5. Do I need any background to start Functional Human Anatomy?

    No. It's pitched at an intermediate level, so it starts where you are and builds up. If you can tap a phone, you can start.
