Superior cervical ganglion

The superior cervical ganglion ( "upper cervical ganglion " ), referred to in animals cervical ganglion cranial ( " anterior cervical ganglion " ), is a nerve cell nodes in the region of the second cervical vertebra. It is the switching station of the sympathetic for the head and the head near the neck. The sympathetic root cells are in the first thoracic segments of the spinal cord and travel through the neck portion of the sympathetic trunk and the trunk vagosympathicus to the superior cervical ganglion.

From the superior cervical ganglion drag multiple pathways to their supply areas:

  • Jugular nerve: This nerve controls the IX. and tenth cranial nerves (glossopharyngeal and vagus ) sympathetic fibers.
  • Internal carotid nerve: He umspinnt the internal carotid artery and thus forms the internal carotid plexus. From him spring from the deep petrosal nerve, which contributes to the greater petrosal nerve of the seventh cranial nerve (facial nerve ) sympathetic fibers and fibers to the eye (via the ciliary ganglion ) and ear. The failure of the eyes branches leads to Horner 's syndrome.
  • Nervi carotici externi: They form the external carotid artery to the external carotid plexus, are distributed over which the sympathetic fibers to the blood vessels in the head, and the common carotid artery, the carotid plexus communis.
  • Rami laryngopharyngei: They form the pharyngeal plexus to the sympathetic supply of the throat ( pharynx ) and larynx (voice box ).
  • Cervical nerve cardiacus superior: It contains pre-and post-ganglionic fibers to the cardiac plexus ( cardiac plexus ).
  • Autonomic Nervous System
  • Ganglion
