cervical sympathetic chain

The cervical sympathetic chain is a bundle of nerves located in the neck, part of the sympathetic nervous system, which controls the body's "fight or flight" responses. This chain runs alongside the spinal column and is involved in regulating functions such as heart rate, blood pressure, and sweating. It plays a key role in how the body reacts to stress and danger. By influencing various organs, the cervical sympathetic chain helps manage bodily responses to different situations, contributing to overall health and well-being.
