Summary
Acupuncture needle insertion at the Jingbi point penetrates the anterior scalene muscle, potentially affecting the brachial plexus. Deeper insertion was noted in male subjects compared to females.
Area of Science:
- Anatomy
- Neuroanatomy
- Acupuncture Research
Background:
- Investigated the anatomical and neuroanatomical relationships of the acupuncture point Jingbi.
- Explored potential neural pathways affected by acupuncture stimulation at Jingbi.
Purpose of the Study:
- To examine the stratified anatomy of the Jingbi acupuncture point.
- To determine the neuroanatomical relationship between Jingbi and the brachial plexus.
- To investigate neural pathways influenced by needling Jingbi.
Main Methods:
- Dissection of 12 human specimens to trace acupuncture needle pathways.
- Analysis of stratified anatomy and neuroanatomical connections to the brachial plexus.
- Comparative analysis of needling depth based on gender and side.
Main Results:
- Needles inserted at Jingbi punctured the anterior scalene muscle, positioned near the brachial plexus.
- Male subjects exhibited significantly deeper needle insertion (approx. 8mm) compared to female subjects.
- Needle proximity to the brachial plexus varied between left and right sides.
Conclusions:
- Deep needling at Jingbi can involve the anterior scalene muscle.
- Acupuncture's mechanism at Jingbi may involve the brachial plexus.
- Gender-based differences in needling depth require further investigation.

2.1K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
