The stellate ganglia may be cut in order to decrease the symptoms exhibited by Raynaud's phenomenon and hyperhydrosis (extreme sweating) of the hands. Injection of local anesthetics near the stellate ganglion can sometimes mitigate the symptoms of sympathetically mediated pain such as complex regional pain syndrome type I (reflex sympathetic dystrophy), and symptoms associated with alterations ...
There are usually 22–23 pairs of these ganglia: three cervical ganglia, 12 thoracic ganglia (the stellate ganglion (cervicothoracic) is formed from the fusion of the first thoracic ganglion with the inferior cervical ganglion), four lumbar ganglia, and four or five sacral ganglia. In the area of the coccyx there is a small ganglion impar. The ...
The sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system.It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated.
There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. The shorter preganglionic neurons originate in the thoracolumbar division of the spinal cord specifically at T1 to L2~L3, and travel to a ganglion, often one of the paravertebral ganglia, where they synapse with a postganglionic neuron.
The treatment is known as SGB (stellate ganglion block), which can also be referred to as CSB (cervical sympathetic blockade). The stellate ganglion is treated with an injection of local anesthetic (numbing medicine) to block the sympathetic nerves located on either side of the voice box in the neck.
Subclavian loop (ansa subclavia), also known as Vieussens' ansa after French anatomist Raymond Vieussens (1635-1715), is a nerve cord that is a connection between the middle and inferior cervical ganglion which is commonly fused with the first thoracic ganglion and is then called the stellate ganglion.

The term "ganglion" refers to the peripheral nervous system. [1] However, in the brain (part of the central nervous system), the basal ganglia are a group of nuclei interconnected with the cerebral cortex, thalamus, and brainstem, associated with a variety of functions: motor control, cognition, emotions, and learning.
