Upper Arm Points Flashcards
LI 14: BINAO Upper Arm’s Musculature
Ask the person to abduct their upper arm to expose the deltoid muscle. Find the ‘V’ of the insertion of the deltoid, on the upper arm. With the arm relaxed by the person’s side and the elbow bent, feel for the point just anterior to this insertion, on the line connecting LI 12 - LI 15. The point lies here at 7 cun above the flexure of the elbow.
TB 13: NAOHUI Upper Arm Convergence
On the posterior surface of the arm, just inferior to the posterior border of the deltoid muscle. It lies at 8 cun superior to the tip of the olecranon. Abduct the person’s arms to highlight deltoid.

LOCATION
On the posterior aspect of the humerus, on the line con- necting the tip of the olecranon and SJ-14 (jian liao), 3 cun below SJ-14 (jian liao), and on the posterior and inferior bor- der of the deltoid muscle.
LOCATION GUIDE
Have the patient adduct their arm. Locate this point on the posterior aspect of their arm, posteroinferior to the border of the deltoid muscle, 3 cun inferior to the acromial angle.
Pe 2: TIANQUAN Heavenly Spring
7 cun above the flexure of the elbow (Pc 3), between the two heads of the biceps muscle. The easiest way to identify the point is to ask the patient to move their arm in two ways to reveal the cun and muscle landmarks. Ask the patient to raise their forearm against the resistance of your hand to highlight the biceps
muscle and reveal the gap between the heads of the biceps. Notice that on someone with welldeveloped biceps muscles this looks like the mid-line of the anterior surface of the arm, but on someone with smaller muscles it may appear to be more
medial than you would have expected visually.

LOCATION
2 cun distal to the end of the anterior axillary fold, between the two heads of the biceps brachii muscle.
LOCATION GUIDE
Have the patient stretch his or her arm forward with his or her palm upward. Locate the point on the anterior aspect of the arm, 2 cun below the end of the axillary fold, between the septum of the long head and the short head of biceps brachii muscle. The distance from the end of the axillary fold to the transverse cubital crease PC-3 (qu ze) is mea- sured as 9 cun.
Lu 3: TIANFU Heavenly Treasury
6 cun above the flexure of the elbow (Lu 5), on the posterio-lateral border of the biceps muscle in the seam between the bone and the muscle. Ask the patient to raise their forearm against the resistance of your hand to reveal the biceps muscle. As with Pc 2 the position of the posterior border of the biceps varies enormously depending on a person’s build. Put your fingers on the lateral surface of the patient’s arm where you can feel the humerus. bone. Palpate anteriorly until they fall into the seam
between bone and muscle. This is the line of the
Lung Channel.
Find 6 cun by dividing the 9 cun length into 3 equal
parts.
