GANGLIA
Ganglia that contain cell bodies of sensory neurons; these are not synaptic
stations.
- Dorsal root ganglia of all spinal nerves
- Sensory ganglia of cranial nerves
- Trigeminal (semilunar, Gasserian) ganglion of trigeminal (V) nerve
- Geniculate ganglion of facial (VII) nerve
- Spiral ganglion (contains bipolar neurons) of
vestibulocochlear (VIII) nerve
- Vestibular ganglion (contains bipolar neurons)
of vestibulocochlear (VIII) nerve
- Superior and inferior ganglia of glossopharyngeal (IX) nerve
- Superior and inferior ganglia of vagus (X) nerve
Ganglia that contain cell bodies of autonomic (postsynaptic) neurons; these
are synaptic stations.
- Sympathetic
ganglia
- Sympathetic trunk (paravertebral or vertebral chain) ganglia
- Prevertebral ganglia (adjacent to origins of large branches of abdominal aorta),
including celiac, superior mesenteric, inferior mesenteric, and aorticorenal ganglia
- The adrenal medulla
Head ganglia
- Ciliary ganglion of oculomotor (III) nerve
- Geniculate ganglion of facial (VII) nerve
- Submandibular ganglion of facial (VII) nerve
- Pterygopalatine (sphenopalatine) ganglion of facial (VII) nerve
- Otic ganglion of glossopharyngeal (IX) nerve
Terminal (intramural) ganglia (near or in wall of organs) including ganglia of submucosal (Meissner's) and myenteric (Auerbach's) plexuses of the intestine
and isolated ganglion cells in variety of organs.
Location: on the dorsal (posterior) root of the spinal nerve. Each segment of
the spinal cord has two ganglia, one on each side in the
posterolateral position.
Function: afferent component of the peripheral
nervous system, the site of sensory cell bodies that conduct impulses to the central nervous system
Composition:
Location: paravertebral, prevertebral, and terminal
locations
Function: the site of efferent cell bodies and synaptic stations of autonomic nervous system
(sympathetic and parasympathetic)
Composition:
