  • The trigeminal nerve exits at the mid pons anteriorly, courses through the prepontine cistern (cisternal portion), and crosses the porus trigeminus to enter a prolongation of dura at the apex of the petrous temporal bone known as the Meckel cave (cavernous portion) where its fibers form the trigeminal ganglion, which is also known as the Gasserian or semilunar ganglion. (pacs.de)
  • It consists of a sensory root and a smaller motor root, the latter which bypasses the trigeminal ganglion inferiorly. (pacs.de)
  • The semilunar (gasserian or trigeminal) ganglion is the great sensory ganglion of CN V. It contains the sensory cell bodies of the 3 branches of the trigeminal nerve (the ophthalmic, mandibular, and maxillary divisions). (medscape.com)

  • Inasmuch as both sympathetic and parasympathetic ganglia are stimulated by levels of nicotine derived from tobacco smoking, the end result depends on the summation of the effects of autonomic ganglion stimulation and reflex effects. (nih.gov)
  • Direct sympathetic innervation of the salivary glands takes place via preganglionic nerves in the thoracic segments T1-T3 which synapse in the superior cervical ganglion with postganglionic neurons that release norepinephrine, which is then received by β-adrenergic receptors on the acinar and ductal cells of the salivary glands, leading to an increase in cyclic adenosine monophosphate (cAMP) levels and the corresponding increase of saliva secretion. (wikidoc.org)
  • The afferent fibers (somatic sensory, sympathetic, and taste) have their cells of origin in the jugular ganglion and in the nodosal ganglion (ganglion of the trunk) and on entering the medulla divide into ascending and descending branches as do the sensory fibers of the posterior roots of the spinal nerves after they enter the spinal cord.
