The meridian system is the same way. Yin (negative) energy off Conception, and Yang energy off the Governing vessel. Both energies are mixed together, and then split into the different sides of the body.
This is the basic "western" explanation of the purpose and way the vessels function distributing Chi energy.
Dangers of the Vessels
When it comes to self defense attacking the pressure points on the Kyusho Jitsu Vessels will yield you a strong result. Many of these pressure points when used in conjunction with other pressure points can also be deadly.
However the body does protect the center-line. This is an instinct, the same as how the brain will protect the eyes. This means once again you cannot just stand and FIGHT. You need to move, and move on angles.
Moving on angles opens up these pressure points, front and back to successful attack. Read more about Octagon Movement here.
Alarm Points are even more effective! The pressure points of the Governor Vessel also have very special purposes. Discussed in Kyusho Pressure Point Anatomy.
