| | Autonomic pathways to the ipsilateral head and upper extremity are interrupted by a block of this ganglion. | | | Blockade of the ganglion impar (also called the ganglion of Walther or sacrococcygeal ganglion) provides pain relief without significant somatovisceral dysfunction for many patients with advanced cancer. | | | The ganglion impar, the only unpaired autonomic ganglion, lies anterior to the sacrococcygeal junction and can be blocked with 5–10 cc of solution administered through a needle penetrating the anococcygeal ligament or directly passing through the sacrococcygeal (calcified) ligament |

| | This ganglion is located immediately next to the internal and external carotid arteries which will supply most of the head structures. | | | Generally, there is one ganglion for each spinal nerve, but neighboring ganglia may fuse into larger masses as in the Cervical region where there are only three large ganglia; Superior, Middle and Inferior. | | | The notion of sensory (i.e., afferent) fibers does not fit well into this system - and so, most people tend to ignore it until they are hard-pressed to explain some subtle visceral pain. |

| | Autonomic nervous system (Anatomy 350A at UWO) |
| | The activities of the autonomic nervous system are subject to control by descending central pathways from the amygdala, septal area, hypothalamus and reticular formation. | | | Visceral pain is often referred to somatic structures supplied by the same spinal segments as the affected organ. | | | Most sensory neurons for visceral reflexes (and also for conscious sensation of fullness) have cell bodies in the inferior ganglion of the vagus nerve, and axons that accompany the preganglionic parasympathetic fibers. |

| | Ganglion - Wikipedia, the free encyclopedia |
| | There are two major groups of ganglia: spinal ganglia and autonomic ganglia. | | | In vertebrate anatomy, a ganglion is a tissue mass that contains the dendrites and cell bodies (or "somata") of nerve cells, in most case ones belonging to the peripheral nervous system. | | | Within the central nervous system such a mass is often called a nucleus. |

| | • Autonomic reflexes occur over autonomic reflex arcs. | | | • Somatic nervous system – consciously perceived sensations – excitation of skeletal muscle – one neuron connects CNS to organ • Autonomic nervous system – unconsciously perceived visceral sensations – involuntary inhibition or excitation of smooth muscle, cardiac muscle or glandular secretion – two neurons needed to connect CNS to organ | | | • Not aware of autonomic responses because control center is in lower regions of the brain |
