Human Anatomy: Form and Function, a free science course on Tomo

Human Anatomy: Form and Function

Bridge the gap between basic body parts and true functional anatomy. Discover how bones, muscles, nerves, and organs mechanically coordinate to sustain motion, regulate pressure, and maintain life.

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

20 levels across 3 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through Mechanical Architecture and Movement; Internal Logistics and Fluid Dynamics; and Coordination, Regulation, and Defense. It assumes you already know the basics.

What you'll learn

Key ideas in Human Anatomy: Form and Function

  • The acromion provides a rigid landmark roughly 5 cm above the axillary nerve
  • Tuffier's line spans both iliac crests to reliably identify the L4-L5 interspace
  • The ulnar nerve runs directly posterior to the humerus's medial epicondyle
  • The superficial back line links plantar fascia, Achilles tendon, and hamstrings
  • Fascia transfers strain longitudinally across joints rather than absorbing it locally
  • Tight hamstrings transmit tensile load downward into the plantar aponeurosis
  • The sagittal plane governs flexion and extension, checking anteroposterior shear
  • The frontal plane governs abduction/adduction, exposing collateral ankle ligaments
  • The transverse plane governs rotation, with the dens providing the primary pivot
  • Muscle spindle activation in the agonist stimulates Ia inhibitory interneurons
  • Ia interneurons suppress alpha motor neurons supplying the antagonist muscle
  • Failure of reciprocal inhibition produces co-contraction and limits joint excursion
  • Spinal curves flex dynamically under load, converting vertical impact into distributed spring tension.
  • A straight bony pillar concentrates axial shock straight into disc tissue instead of dampening it.
  • Alternating cervical, thoracic, and lumbar curves balance gravity directly over the pelvis.
  • Forward flexion compresses the anterior margins of adjacent vertebral bodies.
