Conception Vessel - Ren Mai

Conception Vessel:

The Conception Vessel emerges in the perineum and travels up the anterior midline to the center of the chin. To find the points, you need to use a measurement called a cun (pronounced soon). This measurement is different on everyone. The way to measure it out, is to know body landmarks and to memorize the number of units located between certain ones.
For the conception vessel, you need to remember that from the pubic symphasis (pubic bone) to the umbilicus (belly button) there are 5 measurements (units of cun). All of the points are on the anterior midline. To name all the points, I will refer to the conception vessel as CV.

CV 1- located at the perineum, midway between scrotum and anus.
CV 2- located at the superior border of the pubic symphasis (ps)
CV 3- located 1 cun superior to the PS
CV 4- located 2 cun superior to the PS
CV 5- located 3 cun superior to the PS
CV 6- located 3.5 cun superior to the PS
CV 7- located 4 cun superior to the PS
CV 8- in the center of umbilicus

Now that we have reached the umbilicus, I'll need you to remember another number. The distance between the umbilicus and the sternocostal angle is 8 cun. Let's move on.

CV 9- located 1 cun above umbilicus
CV 10- located 2 cun above umbilicus
CV 11- located 3 cun above umbilicus
CV 12- located 4 cun above umbilicus
CV 13- located 5 cun above umbilicus
CV 14- located 6 cun above umbilicus
CV 15- located 7 cun above umbilicus
CV 16- located at the sternocostal angle

For the next set of points, you'll need to be able to feel the spaces between ribs and then move your finger over to the spot on the sternum which is level with that rib space.

CV 17- level with the 4th intercostal space at sternum
CV 18- level with the 3rd intercostal space at sternum
CV 19- level with the 2nd intercostal space at sternum
CV 20- level with the 1st intercostal space at sternum

For the rest of the points, we will use landmarks:

CV 21- midway between CV 20 and CV 22
CV 22- in the deepest part of the fossia above the sternum
CV 23- On the midline, in the depression above the hyoid bone.
CV 24- Above the chin, the in depression in the center of the mentolabial groove.

Some of these points have notable mention:
CV3- Front Mu of Bladder
CV4- Front Mu of Small Intestine
CV5- Front Mu of Sanjiao
CV6- Sea of Qi
CV12- Front Mu of Stomach
CV14- Front Mu of Heart
CV15- Luo Point
CV17- Front Mu of Pericardium
