The cervical caudal ganglia is considered a nerve connection located in the mid-cervical spine. In total, up to twelve lateral cervical ganglia are identified, mainly on the right. They are located near the spine between the ninth and tenth vertebrae in the area of the sternocleidomastoid muscle in the place where it passes to the shoulder girdle. The cervical ganglia are small, round structures measuring approximately 5 to 8 mm in diameter. Externally, they look like elongated heads of muscle tissue. The fibrous fibers within them are oriented transversely with many finely branched transverse bars between them.
Among neurologists, the formation is considered relatively safe, but due to its location it is associated with a variety of diseases. Contributing factors are prolonged static posture or sudden movements in the cervical spine. The cervical caudal ganglion most often becomes inflamed with cervical osteochondrosis, herniated intervertebral discs and instability or entrapment of the intervertebrae
