Here are some highlights from Day 2, though the coup de grace on the old anatomy was delivered by Jaap van der Wal, but more on him later.
The theme of the day was the sideways connections of the fascia within the muscle. Jst how does the muscle convey its force to the fascia and vice versa?
Carla Stecco of the famous Stecco family started the day by tracing the ‘trellis’ (I would say onion bag) arrangement of the fascia at rest, with additional ‘crimping’ in the tissue. Dense irregular tissue is not ‘irregular’ at all, but has a variety of directions at very precise angles for dealing with the forces. What slides, and what is fixed?
How much is the thoracolumbar fascia a sense organ and how much a force transmitter? asks Jonas Tesarz.
Jean_Paul Delage, working with Guimberteau, shows the cells in the paratendon (what we used to think of as the sheath).
Peter Purslow showed great pictures of the honeycomb of the endomysium, showing the same angle of fibers Stecco described, which go longitudinal when the muscle is stretched, and go circumferential when the muscle is contracted. Interestingly, while the endomysium is well-equiped to transmit force, the perimysium – which is continuous with the epimysium – is poorly constructed to transmit force – so what it is for?
