“…Hypertrophy is a widely known adaptive mechanism during postnatal development in most autonomic ganglia from medium‐sized to large mammals (Miolan and Niel, 1996; Gagliardo et al, 2005; Fioreto et al, 2007). As with previous studies (Ribeiro et al, 2004; Gagliardo et al, 2005; Ribeiro, 2006; Toscano et al, 2009) preá postnatal development was marked by a 77% increase in the SCG volume, which was accompanied by a 7000‐fold increase in the animal body weight.…”

Whilst a fall in neuron numbers seems a common pattern during postnatal development, several authors have nonetheless reported an increase in neuron number, which may be associated with any one of a number of possible processes encapsulating either neurogenesis or late maturation and incomplete differentiation. Recent publications have thus added further fuel to the notion that a postnatal neurogenesis may indeed exist in sympathetic ganglia. In the light of these uncertainties surrounding the effects exerted by postnatal development on the number of superior cervical ganglion (SCG) neurons, we have used state-of-the-art design-based stereology to investigate the quantitative structure of SCG at four distinct timepoints after birth, viz., 1-3 days, 1 month, 12 months and 36 months. The main effects exerted by ageing on the SCG structure were: (i) a 77% increase in ganglion volume; (ii) stability in the total number of the whole population of SCG nerve cells (no change--either increase or decrease) during post-natal development; (iii) a higher proportion of uninucleate neurons to binucleate neurons only in newborn animals; (iv) a 130% increase in the volume of uninucleate cell bodies; and (v) the presence of BrdU positive neurons in animals at all ages. At the time of writing our results support the idea that neurogenesis takes place in the SCG of preás, albeit it warrants confirmation by further markers. We also hypothesise that a portfolio of other mechanisms: cell repair, maturation, differentiation and death may be equally intertwined and implicated in the numerical stability of SCG neurons during postnatal development.

“…The ganglia of the sympathetic chain in the cervical region are classically into three bilaterally ganglia; cranial, middle and caudal cervical ganglion (Rosse & GaddumRosse, 1997;Fioretto et al, 2003;Gabella, 2004). Occasionally, there is a vertebral ganglion on the vertebral nerve, (Rosse & Gaddum-Rosse).…”

ABUMANDOUR, M. M. A. & EL-DEFRAWY, F.Morphological investigations of the cervicothoracic sympathetic system in the horse (Equus ferrus caballus) in Egypt. Int. J. Morphol., 34(3):923-933, 2016. SUMMARY:The current study was performed on twelve healthy adult horses (E. ferrus caballus) collected from Egypt were dissected to provide anatomical descriptions of bilaterally cervicothoracic sympathetic system macroscopically. On the left side, cervicothoracic sympathetic system is represented only by the caudal cervical ganglion, which presents on lateral surface of esophagus, cranial to the level of first rib. On right side, cervicothoracic sympathetic system is represented by the caudal and middle cervical ganglion. Caudal cervical ganglion was consisted of the fusion of eighth cervical and first three thoracic nerve ganglia. Caudal directed continuation branch of left ansa subclavia gave off a pericardial branch and then gave branch for ligamentum arteriosum. There are special sympathetic-parasympathetic communicating branches; on left side, there is only one branch that was present on lateral surface of esophagus, while on right side, there were four branches; two from caudal cervical ganglion and two from middle cervical ganglion. The most suitable site of ganglion blocks from both sides; needle was placed medioventrally between the articulation of first and second rib.

“…In all mammals, the autonomic nervous systems were consisted of nerves and ganglions that connected to the central nervous system on one side and to the viscera on the other side. The ganglia of the sympathetic chain in the cervical region are classically arranged into three bilaterally ganglia; cranial, middle and caudal cervical ganglion (Fioretto et al, 2003;Gabella, 2004;Rosse and Gaddum-Rosse, 1997). Occasionally, there is a vertebral ganglion on the vertebral nerve, (Rosse and Gaddum-Rosse, 1997).…”
