Saanen keçilerinde servikal sempatik ganglion’ların anatomisi

Abstract

Sympathetic ganglions located in the cervical region are important organs that make the final synapse of the sympathetic nerve fibers reached to the head, neck, and forelimbs. No anatomical data about cervical sympathetic ganglia was found in Saanen goat. Therefore, we determined the nerve branches separated from the ganglia and the location of the ganglia, and also, the expression of enzyme and protein such as tyrosine hydroxylase (TH), dopamine β-hydroxylase (DβH), neuropeptide Y (NPY) and substance P (SP) in ganglia. GCC was in the medial place of bulla tympanica. Mainly branches named as nn. carotici interni, n. jugularis, n. caroticus externus was found to be separated from this ganglion and thin branches joined to the nearby nerve. GCI were not found in all dissections and histological examinations. It was found that vertebral nerve, the two branches that constitute the subclavian ansa, and the thin nerve branches involved in the surrounding tissues and organs were separeted from GCT that located in the first intercostal space. A total of 5 GCM were found at the junction of the two branches forming the ansa subclavia. DßH, TH, NPY and SP were revealed to be express in all ganglia. DßH and NPY in GCC, TH in GCM, DβH, NPY and TH in GCT were found to be more intense staining
