The middle cervical ganglion is the smallest of the three cervical ganglia and is occasionally absent. It is placed opposite the sixth cervical vertebra usually in front of or close to the inferior thyroid artery. It sends gray rami communicantes to the fifth and sixth cervical nerves and gives off the middle cardiac nerve.It is probably formed by the coalescence of two ganglia corresponding to the fifth and sixth cervical nerves.
