The cervical sympathetic chain is a part of the sympathetic nervous system, which is one of the two divisions of the autonomic nervous system. The sympathetic nervous system is responsible for the body's "fight or flight" response to stress or danger, and it plays a crucial role in maintaining homeostasis, or balance, in the body.
The cervical sympathetic chain is a series of ganglia, or clusters of nerve cells, that run along the sides of the neck. These ganglia are connected to the spinal cord by nerves that transmit signals between the brain and the rest of the body. The cervical sympathetic chain is responsible for controlling the blood flow and sweat production in the head and neck, as well as the constriction of blood vessels and pupils.
There are several important functions of the cervical sympathetic chain. One of its primary roles is to regulate blood flow to the head and neck. When the body is under stress or in danger, the cervical sympathetic chain sends signals to the blood vessels in the head and neck to constrict, which reduces blood flow and helps to protect the brain from injury. At the same time, the cervical sympathetic chain also activates the sweat glands in the head and neck, which helps to cool the body and prevent overheating.
In addition to its role in regulating blood flow and sweat production, the cervical sympathetic chain also plays a role in controlling the pupils of the eyes. When the body is under stress or in danger, the cervical sympathetic chain sends signals to the pupils to constrict, which helps to improve vision and focus attention.
There are several conditions and disorders that can affect the cervical sympathetic chain. One common disorder is thoracic outlet syndrome, which is caused by compression of the nerves and blood vessels in the neck. This condition can cause pain, numbness, and tingling in the neck, shoulders, and arms. Other conditions that can affect the cervical sympathetic chain include neck injuries, infections, and tumors.
In conclusion, the cervical sympathetic chain is an important part of the sympathetic nervous system that plays a crucial role in maintaining homeostasis in the body. It is responsible for regulating blood flow and sweat production in the head and neck, as well as controlling the constriction of blood vessels and pupils. Understanding the functions and disorders of the cervical sympathetic chain is important for diagnosing and treating a range of conditions and disorders.
Schwannoma of cervical sympathetic chain
They emerge from the spinal cord through the seven cervical vertebrae. What is the function of the sympathetic chain? Interruption of the cervical sympathetic chain is one cause of Horner's syndrome. Stellate ganglion blockade for the treatment of refractory ventricular arrhythmias. Complications associated with stellate ganglion nerve block: A systematic review.

Preganglionic nerves from the thoracic spinal cord enter into the cervical ganglions and synapse with its postganglionic fibers or nerves. Also, the vagus nerve can be followed distinctly from the tumor. Regional nerve blocks in anesthesia and pain therapy: traditional and ultrasound-guided techniques. The lesion is longitudinally oriented without neural foraminal extension.
Block of the superior cervical ganglion, description of a novel ultrasound-guided technique in human cadavers. The physician tested for streptococcal pharyngitis, but the test results were negative, and the patient was treated with over-the-counter medication. That surrounding the external maxillary artery communicates with the submaxillary ganglion by a filament; and that accompanying the middle meningeal artery sends an offset to the otic ganglion, and a second, the external petrosal nerve, to the genicular ganglion of the facial nerve. It is connected with other branches of the sympathetic; about the middle of the neck it receives filaments from the external laryngeal nerve; lower down, one or two twigs from the vagus; and as it enters the thorax it is joined by a filament from the recurrent nerve. Localization of the superior cervical ganglion for targeted anesthetic blockade.
The parasympathetic nervous system restores the body to a calm and composed state and prevents it from overworking. All preganglionic fibers, whether they are in the sympathetic division or in the parasympathetic division, are cholinergic that is, these fibers use acetylcholine as their neurotransmitter and they are myelinated. Those fibers from the middle cervical ganglion supply the C5 and C6 nerve roots along with the cardiac plexus and thyroid gland. Superior cervical sympathetic ganglion block under ultrasound guidance promotes recovery of abducens nerve palsy caused by microvascular ischemia. This loop is named the ansa subclavia Vieussenii. Reflex sympathetic dystrophy of the face and neck: report of 6 patients treated with stellate ganglion block.

A schwannoma is a benign tumor, so most surgeons will use a subcapsular technique or enucleation. The patient was referred to Vanderbilt Bill Wilkerson Center in Nashville, Tennessee, to discuss possible courses of action. New York: Thieme, Stuttgart; 1991.
These tumors will displace the 3. The offsets to bloodvessels form plexuses on the subclavian artery and its branches. Where is the sympathetic chain ganglia located? There is no frank evidence of local invasion. Laterally is the ipsilateral vertebral artery. The Lateral Branches external branches consist of gray rami communicantes to the upper four cervical nerves and to certain of the cranial nerves. Korean J Hosp Palliate Care. The pharyngitis improved within several days; however, the patient returned to his primary care physician several weeks later because the neck swelling had not abated.
Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub. The local pathologist identified spindle cell proliferation but did not identify lymphoid tissues on the sample. Laryngoscope 108:1009—1013 Cite this article Jain, S. Cham: Springer International Publishing; 2015. Ultrasound imaging for stellate ganglion block: direct visualization of puncture site and local anesthetic spread. Comparison of effectiveness of stellate ganglion block between chronic tension headache and chronic migraine patients.
Cite this chapter Tumber, P. Thus, the cervical ganglia are not associated with white rami communicantes carrying preganglionic fibres - preganglionic fibres ascend from the thoracic part of the trunk. Hyperbaric oxygen and stellate ganglion blocks for idiopathic sudden hearing loss. What systems are only innervated by the sympathetic nervous system? The most common tumour arising primarily from this region is a neurogenic tumour, especially Schwannoma. Stellate block for trigeminal zoster.
This massive thickening at the top of the sympathetic trunk is the superior cervical ganglion. What is cervical part of sympathetic trunk? From the superior cervical ganglion, post-ganglionic fibers arise, which divide into: anastomoses with the lower cranial nerves and with the first four cervical nerves, via gray rami communicantes. Cardiac arrest following stellate ganglion block performed under ultrasound guidance. Is vagus nerve sympathetic or parasympathetic? Its form is irregular; it is larger in size than the preceding, and is frequently fused with the first thoracic ganglion. Consideration of the immediate risks and benefits favors the watch-and-wait option. A case of sympathetically mediated headache treated with stellate ganglion blockade. The otorhinolaryngologist scheduled an ultrasound-guided fine-needle aspiration biopsy, which was conducted without complications.
