It carries motor, sensory, and autonomic (sympathetic) signals between the spinal cord and the body. It is commonly discussed when evaluating arm\/hand symptoms near the cervicothoracic junction (where neck meets upper back). It also matters in imaging, injections, and surgery involving the T1\u2013T2 foramen and nearby structures."}
