Scar: Epidural row standard scar #3, post -> ant
Myochains
Location: 1 fw medial to STL
Direction: drag medial
Slight anterior bias (T1-12 only) for posterior myochains
Slight posterior bias (C/T/L regions) for anterior myochains
Foot at lambdoidal suture, hip-sac at curve, thoracic top, cervical 1 fw anterior to coronal suture, continue to TMJ myochains and eye.
Scar: Epidural row standard scar #3, post -> ant
Eye myochains
Location: 1 fw medial to STL, standard lymphatic row

Ear ligament
Location: 1 fw inferior to STL, 1-2 fw above eyebrow, scans ALL
Direction:
Superficial fascia
Location: along line of maxilla
Direction: Upper quadrant drag posteriorly (chin to ST6 = hand to thorax); lower quadrant drag anteriorly (ST6 to chin = thorax to foot)
Scar: same direction for each but on the line just under the maxilla
Spinal disc and annulus
Location: posterior to lamdoidal suture
Direction: superior toward suture (lumbar at top, cervical near occiput)
Scar: just above lamdoidal suture dragging laterally in each direction
Costal cartilage
Location: forehead ridge and occipital ridge
Direction: medial to lateral on forehead (T1 to T7); medial to lateral on occiput (T8-T10)

Scar: ?
Periosteal
Location: along the STL
Direction: posterior
Bias added for flexed segments, begin above and drag into STL; for extended segments begin below and drag into STL along posterior directions for both. Limbs unbiased.
Cranium near eyebrow, foot at lamdoidal suture
Scar: Angle anterior-superior along STL
Pericardial
