Cervical sympathetic chain Rating: 4,3/10 1585 reviews

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.

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.

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.
