The superior cervical ganglion (SCG) is the upper-most and largest [1] of the cervical sympathetic ganglia of the sympathetic trunk. [1] [2] It probably formed by the union of four sympathetic ganglia of the cervical spinal nerves C1–C4. [1] It is the only ganglion of the sympathetic nervous system that innervates the head and neck.

Mar 30, 2023 · The superior cervical ganglion is the most superior ganglion of the sympathetic chain, bilaterally. It is the largest of the three ganglia of the cervical sympathetic trunk, the other two being the stellate and middle cervical ganglion.[1]

Jan 22, 2025 · The superior cervical ganglion is the largest of the three cervical sympathetic ganglia and is located in the neck. It is positioned at the level of the second and third cervical vertebrae (C2–C3) and lies anterior to the transverse processes of these vertebrae.

Sep 5, 2024 · The superior cervical ganglion is located posteriorly to the carotid artery, and anterior to the C1-4 vertebrae. Several important post-ganglionic nerves originate from here: Internal carotid nerve – hitch-hikes along the internal carotid artery, forming a network of nerves.

Aug 28, 2024 · The superior cervical ganglion provides sympathetic innervation to the head and neck. The lower pole of the ganglion is connected to the sympathetic trunk and receives preganglionic nerve fibers.

The superior cervical ganglion is the largest of the cervical ganglia and lies inferior to the occiput and anterior to the transverse processes of the second and third cervical vertebrae, in front of the longus capitis muscle (Civelek et al., 2008).

Hadley and Dale Purves have examined mouse nerve cells on the surface of a cluster of cells, called the superior cervical ganglion, located in the animal's neck.

Superior cervical ganglion is an elongated oval-shaped ganglion that marks the superior extent of the cervical sympathetic trunk. It is situated at the level of second and third cervical vertebrae (C2–C3).

Mar 30, 2023 · The superior cervical ganglion is the most superior ganglion of the sympathetic chain, bilaterally. It is the largest of the three ganglia of the cervical sympathetic trunk, the other two being the stellate and middle cervical ganglion.

Oct 30, 2023 · 23 pairs of ganglia can be found: 3 in the cervical region (which fuse to create the superior, middle and inferior cervical ganglions), 12 in the thoracic region, 4 in the lumbar region, four in the sacral region, and a single, and the unpaired ganglion impar mentioned above.
