A ganglion (pl.: ganglia) is a group of neuron cell bodies in the peripheral nervous system. In the somatic nervous system , this includes dorsal root ganglia and trigeminal ganglia among a few others.
The trigeminal ganglion (also known as: Gasserian ganglion, semilunar ganglion, or Gasser's ganglion) is the sensory ganglion of each trigeminal nerve (CN V). The trigeminal ganglion is located within the trigeminal cave (Meckel's cave) , a cavity formed by dura mater .
Ganglion cells within a ganglion. H&E stain . In neurophysiology , a ganglion cell is a cell found in a ganglion (a cluster of neurons in the peripheral nervous system ).
A dorsal root ganglion (or spinal ganglion; also known as a posterior root ganglion [1]) is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve. The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia. [2] The axons of dorsal root ganglion neurons are known as afferents.
The bilaterally symmetric sympathetic chain ganglia, also called the paravertebral ganglia, are located just ventral and lateral to the spinal cord. [3] The chain extends from the upper neck down to the coccyx, forming the unpaired ganglion impar. Ganglia within this chain are either cervical, thoracic, lumbar, or sacral.
Stellate ganglion is located at the level of C7, anterior to the transverse process of C7 and the neck of the first rib, superior to the cervical pleura and just below the subclavian artery.
The ciliary ganglion is a parasympathetic ganglion located just behind the eye in the posterior orbit. It is 1–2 mm in diameter and in humans contains approximately 2,500 neurons . [ 1 ] The ganglion contains postganglionic parasympathetic neurons.
The vestibular ganglion (also Scarpa's ganglion) is a collection of cell bodies belonging to first order sensory neurons of the vestibular nerve. It is located within the internal auditory canal . [ 1 ] [ 2 ] [ 3 ]
