Anatomy Trains terms
The following is a glossary of terms particular to this topic.
Standard anatomical terminology is for the most part not
included, and can be found in any medical dictionary.
vectors; in simple language, a bony landmark where
many muscles meet, such as the ASIS.
Station A place where the myofascial continuity or
track in the 'outer' myofascial bag is 'tacked down' or
attached to the fascial webbing of the 'inner' bone-
ligament bag - in other words, a muscle attachment.
Switch An area where fascial planes either converge
from two into one, or diverge from one into two.
Track A single myofascial or fascial element in a myo-
Anatomy trains The system of 12 myofascial meridians
described in this topic.
Branch line An alternative track to the primary myo-
fascial meridian, often smaller and employed only under
Cardinal line A cardinal line runs the length of the
body on one of the four major surfaces: the SBL on the
back, the SFL on the front, and the LL on right and left
Derailment A link within a myofascial meridian which
only applies under certain conditions.
Express An express is a multi-joint muscle that thus
enjoys multiple functions.
Helical lines Lines which traverse the body in a spiral,
including the Functional Lines, the Spiral Lines, the
Arm Lines (in practice), and portions of the Lateral
Local A local is a single-joint muscle that duplicates
one of the functions of a nearby or overlying express.
Locked long Used to designate a tense muscle held in
a state longer than its usual efficient length, a muscle
under strain, known in physiotherapy as 'eccentrically
Locked short Used to designate a tense muscle held in
a state shorter than its usual efficient length, a bunched
or shortened muscle, known in physiotherapy as 'con-
Mechanical connection A connection between two
tracks across a station where the connection passes
through an intervening bone.
Myofascial continuity Two or more adjacent and con-
nected myofascial structures.
Myofascial meridian A connected string of myofascial
or fascial structures, one Anatomy Train line.
Roundhouse An area where many myofascial continu-
ities join, which is thus subject to a number of different
Fascia For the purposes of this topic, this term
refers to the body-wide collagenous web or any section
Ground substance Another name for the hydrophilic
proteoglycans which constitute the various colloid inter-
fibrillar elements of connective tissue.
Tensegrity Structures combining tension and compres-
sion where the tension members are determinant of the
structure's integrity, where the compression members
are isolated in a sea of continuous tension.
Thixotropy The tendency of colloids (such as ground
substance) to become more fluid when stirred up by
the addition of mechanical or thermal energy, and to
become more solid or gelatinous when fluid or energy
is extracted or when it sits undisturbed.
