The superior, middle, and inferior cervical ganglia are sympathetic chain ganglia located in the neck and responsible for supplying sympathetic innervation to the head, neck, and upper thorax. The superior cervical ganglion is the largest and provides fibers to structures such as the eyes, salivary glands, and blood vessels of the head. The middle cervical ganglion, though smaller and sometimes absent, contributes fibers to the heart and thyroid. The inferior cervical ganglion often fuses with the first thoracic ganglion to form the stellate ganglion, which distributes sympathetic fibers to the upper limbs and thoracic organs. Together, these ganglia help regulate functions like pupil dilation, sweating, and vascular tone. The Superior Middle and Inferior Cervical Ganglia Diagram - Chart - diagrams and charts with labels.
