“…Moreover, the generally accepted parasympathetic ganglia of the head [ 2 ], which include the ciliary [ 60 – 69 ], the otic [ 69 ], the pterygopalatine [ 69 – 72 ] and the submandibular ganglia [ 69 , 73 – 78 ], all contain catecholaminergic cell bodies. Catecholaminergic cell bodies are found not only in ganglia, but also in the cranial nerves themselves, such as the (lingual branch of the) glossopharyngeal nerve [ 27 , 79 ], the cervical [ 80 ] and laryngeal branches of the vagus nerve [ 81 , 82 ], and the cranial root of the hypoglossal nerve [ 83 ]. In addition, catecholaminergic cell bodies are found in both the ventral and dorsal spinal nerve roots [ 84 – 99 ], and in the hypogastric and the (“parasympathetic”) pelvic splanchnic nerves [ 16 , 17 ].…”

Purpose We have re-evaluated the anatomical arguments that underlie the division of the spinal visceral outflow into sympathetic and parasympathetic divisions. Methodology Using a systematic literature search, we mapped the location of catecholaminergic neurons throughout the mammalian peripheral nervous system. Subsequently, a narrative method was employed to characterize segment-dependent differences in the location of preganglionic cell bodies and the composition of white and gray rami communicantes. Results and Conclusion One hundred seventy studies were included in the systematic review, providing information on 389 anatomical structures. Catecholaminergic nerve fibers are present in most spinal and all cranial nerves and ganglia, including those that are known for their parasympathetic function. Along the entire spinal autonomic outflow pathways, proximal and distal catecholaminergic cell bodies are common in the head, thoracic, and abdominal and pelvic region, which invalidates the “short-versus-long preganglionic neuron” argument. Contrary to the classically confined outflow levels T1-L2 and S2-S4, preganglionic neurons have been found in the resulting lumbar gap. Preganglionic cell bodies that are located in the intermediolateral zone of the thoracolumbar spinal cord gradually nest more ventrally within the ventral motor nuclei at the lumbar and sacral levels, and their fibers bypass the white ramus communicans and sympathetic trunk to emerge directly from the spinal roots. Bypassing the sympathetic trunk, therefore, is not exclusive for the sacral outflow. We conclude that the autonomic outflow displays a conserved architecture along the entire spinal axis, and that the perceived differences in the anatomy of the autonomic thoracolumbar and sacral outflow are quantitative.

“…According to Ohtsuka et al [3] and Oda et al [4], in these nerves, the lingual branches of the glossopharyngeal nerve are notably thick, and they follow a downward course through a slit between the constrictor pharyngis superior and medius muscles (CPS and CPM). Likewise, many atlases of human anatomy (Fig.…”

We examined pharyngeal nerve courses in paraffin-embedded sagittal sections from 10 human fetuses, at 25-35 weeks of gestation, by using S100 protein immunohistochemical analysis. After diverging from the glossopharyngeal and vagus nerves at the level of the hyoid bone, the pharyngeal nerves entered the constrictor pharyngis medius muscle, then turned upward and ran superiorly and medially through the constrictor pharyngis superior muscle, to reach either the levator veli palatini muscle or the palatopharyngeus muscle. None of the nerves showed a tendency to run along the posterior surface of the pharyngeal muscles. Therefore, the pharyngeal nerve plexus in adults may become established by exposure of the fetal intramuscular nerves to the posterior aspect of the pharyngeal wall because of muscle degeneration and the subsequent rearrangement of the topographical relationship between the muscles that occurs after birth.
