Anatomical observation and CT three-dimensional reconstruction of Five-shu acupoints of Shaoyin Heart Meridian in rabbit’s forelimb
Objective To investigate the location and anatomical structure of “Shaochong”(HT9)
“Shaofu”(HT8)
“Shenmen”(HT7)
“Lingdao”(HT4) and “Shaohai”(HT3) in the rabbit's forelimb. Methods Sixteen rabbits(half male and half female) were used in the present study. By referring to the national standards on the location of acupoints in the human body and the literature about the location of acupoints in the rabbit
and by using the method of comparative anatomy
the location and needling operation of the Five-shu acupoints of Shaoyin Heart Meridian on the rabbit's forelimb were defined
and these acupoints were needled and CT three-dimensional reconstruction were conducted. Then
the rabbits were killed
and intravascular perfusion was performed
followed by inserting acupuncture needles into these five acupoints for observing the anatomical relationship between the inserted acupuncture needle and the structure of surrounding tissues. Results HT9 is located at the medial side of the little finger of forelimb
about 1 mm beside the nail root
and is adjacent to the superficial flexor tendon of the finger
the dorsal branches of the proper palmar digital artery and vein
and the endings of dorsal branch of palmar digital proper nerve of the ulnar nerve on the fifth finger side. HT8 is located at the palm side of the forelimb
horizontally parallel to the proximal end of the 5th metacarpophalangeal joint and between the 4th and 5th metacarpal bones
and is adjacent to the lumbricalis
the 4th and 5th interossei
and common palmar digital artery and vein and the palmar digital proper nerve of the ulnar nerve. HT7 is located at the medial margin of the extensor carpal tendon on the ulnar side
between the distal end of the ulna and the ulnar carpal bone
and is adjacent to the tendons of flexor carpi ulnaris and extensor carpi ulnaris
ulnar artery
ulnar vein and ulnar nerve. HT4 is located at the medial border of the ulnar flexor tendon
about 1.5 cun superior to HT7
and is adjacent to extensor carpi ulnaris
flexor carpi ulnaris
flexor digitorum superficialis
flexor digitorum profundus
ulnar artery
vein and ulnar nerve. HT3 is located at the depression
medial to the condyle of humerus when the elbow is bent at 90°
its neighbor structure is composed of pronator teres
biceps brachii
brachial artery and vein
radial collateral artery
radial collateral vein
medial antebrachial cutaneous nerve and median nerve. Conclusion In the rabbit
there is a close relationship between HT9
HT8
HT7
HT4 and HT3 regions and brachial vascular and its branches
cephalic vein and its branches
medial antebrachial cutaneous nerve
median nerve and ulnar nerve
which is the morphological basis of the Five-shu acupoints of Shaoyin Heart Meridian for treating some related clinical disorders.
