The inferior ganglion (g. Inferius) is one of three large nerves that provide nutrition and control of the spinal cord. Located in the lower part of the spine. Unlike other nerve plexuses, the superior and middle ganglia are located close to the spine and therefore do not require special access. The nerves of the lower ganglion, on the contrary, are located deep in the tissues. Despite this circumstance, the inferior ganglion is much easier to operate than the superior ganglion due to the peculiarities of its location.
The inferior ganglion is located in the antumbilical foramen and consists of four sections: iliac, lateral, medial and posterior. The hip flexor innervates the thigh, and the sporus muscle innervates the sporus muscle group of the thigh. The medial and lateral divisions of the spinal nerve of the lower limb form two groups of nerves located on either side of the femur inside the femoral canal. These nerves have an entrance hole and an exit hole.
The lateral part provides innervation to the rotator and adductor muscles and also helps the knee joints move. The medial part of the trunk and the external dimple transmit impulses to the spoiling muscles of the leg. The lower node of the lower tree provides an braking effect, which leads to a decrease in the frequency of contractions and an increase in the amplitude of muscle contractions. For the same purpose, a delay is used - slowing down the electrical activity of the muscle, ensuring a slow progression of fatigue when the load gradually increases during training.
If the inferior ganglion is affected, syringomyelia can develop, a degeneration of the spine that leads to weakening of the muscles on the opposite side, impaired leg movement, numbness and weakness.
