1 Jing luo(Channel and Network Vessel System)1.1.3 Distribution and Organisation of
the Channel and Network Vessel
(jing luo) System
According to the law of the Exterior–Interior (biao-li) the ‘Exterior’
communicates with the ‘Interior’.
Exterior (biao) corresponds to the skin, the muscles and the
pathways of the channel and network vessel superficial (jing
luo) system. The deeper pathways of the channels and the Organ
systems (zangfu) are attributed to the Interior (li). A particular
organisational structure within the jing luosystem is necessary
to safeguard the circulation of Qi and the communication
between the Exterior and the Interior. In this respect, the extra-
ordinary vessels play a special role. While they play a major role
in coordinating and regulating the primary channels and the jing
luosystem in general, they do not directly connect the Interior
and the Exterior. There is also no direct connection between the
extraordinary vessels and the zangfu-Organs (see ➞1.7 and
Chapter 5).Depth organisation of the jing luosystem
Differing ideas exist regarding the depth at which the various
channels and vessels are located within the body. The table
below and Fig. 1.4 show the ideas according to Solinas et al.
(1998) and Deadman et al. (1998) in a modified way. While
these authors regard the deep, Interior pathways of the primaryand divergent channels as the deepest channel structures, other
authors attribute this role to the eight extraordinary vessels (for
the eight extraordinary vessels, see ➞1.7).Overview over the possible location with regard to
