MACROANATOMICAL INVESTIGATION OF THE AORTICORENAL GANGLION IN DOMESTIC PIG ( Sus scrofa domesticus ) IN PERINATAL PERIOD

The macroanatomical research of the aorticorenal ganglion (ARG) was conducted on 14 domestic pigs – 4 males and 10 females of 110 days of gestation. The pigs were obtained from one uterus. The examinations were carried out using the method of macroscopic preparation with a forehead magnifying glass and binocular (magnification 2.0–5.0x). The measurements of the ARG were performed with the aid of an electronic slide-caliper to an accuracy of 0.01 mm. The measurements of studied individuals were summarized with the use of arithmetical means, standard deviation (S.D.) and coefficient of variability (C.V.). According to our study, the ARG is characterized by variable location in relation to the suprarenal gland, the renal artery, the caudal vena cava and the abdominal aorta (syntopy), the thoracic and lumbar segments of the vertebral column (skeletotopy) (between Th 14 -L 5 ) and also by a different shape (triangular and elongated). A double ARG was found in two females on the left side of the body, and a triple ARG also on the left in one female near the suprarenal gland and the renal artery. The ARG size and its location in relation to the caudal end of the suprarenal gland were statistically independent of body size, length, and sex.
