Analiza morfologiczna zwoju szyjno-piersiowego u psow rasy american staffordshire terrier

Stellate ganglion (ganglion cervicothoracicum s. ganglion stellatum) is a part of pars cervical sympathica. Investigations were carry out on fetuses of 16 dogs of the American Staffordshire Terrier (AST) breed, 7 of which were the male and 9 female. The fetuses were taken out from 10 uteruses on the 62nd day of pregnancy. The examination was carried out with a magnifying glass (magnification 1.55.0×) and a stereoscopic microscope. During the preparation, in order to better perceive the anatomical structures, 0.5-2% acetic acid was used. The measurements were taken with an electronic slide caliper to the nearest 0.1 mm. For the investigations methods used in topographical anatomy were applied: i.e. holotopy and sceletotopy. According to our research stellate ganglion of dogs is located in the section between C5-8 and Th1-3. It occurs in the aftermath of a combination of 3 or 4 ganglion: inferior cervical ganglion, first thoracic ganglion, two thoracic ganglion, or tree thoracic ganglion. It is characterized by different location, form, morphometry in relation to sex and body side. Nervous branches spread out of stellate ganglion have also been characterized.
