Some macrometric anatomical parameters of the adrenal glands in the New Zealand white rabbit

Abstract

The anatomical features of the rabbit adrenal glands have been investigated in some aspects, either via classic anatomical methods and routine histology, either using imaging modalities in our previous experiments. The present study is focused for obtaining data, concerning the objective values of three macrometric indices -lateromedial, craniocaudal and dorsoventral diameters. We used the cadavers of thirty-four 8-month old (sexually mature) healthy white New Zealand rabbits weighing 2.8-3.2 kg. We reached the abdominal cavity after median incision. The both kidneys were kept in abdominal cavity with a view to find more easily the location of the right and left adrenal glands. The material was documented using a digital camera. The craniocaudal, dorsoventral and lateromedial diameters have been measured using a digital caliper, as the obtained values were accurate to the second sign. Descriptive analysis of the results using Statistica 8 -StatSoft DELL was performed. The lateromedial diameter of the right adrenal gland was 5.1 mm ± 1.0, craniocaudal diameter was 9.3 mm ± 1.2 and the dorsoventral diameter -5.0 mm ± 0.8. For the left adrenal gland were measured the following values -the lateromedial diameter was 6.5 mm ± 1.2, the craniocaudal diameter was 10. 2 mm ± 1.4 and the dorsoventral diameter was 6.3 mm ± 0.9. Our results showed that the studied parameters of the left gland were with higher values compared to the right gland. The results from the conducted anatomical study deepens the knowledge for the macroscopic features of the rabbit adrenal glands.

Computed tomography and three dimensional anatomical study of the liver in the chinchilla (Chinchilla lanigera)

“…Additionally, we found four lobes, as lobus hepatis dexter has lateral and medial parts. That differs from the theory about lobus hepatis dexter in the rabbit's liver, which has been described as uniform (Stamatova-Yovcheva, 2016).…”

“…The visceral surface of lobus hepatis sinister lateralis and the 'left middle lobe' in the chinchilla's liver is similar to the rabbit's liver (Stamatova-Yovcheva, 2016). These lobes have anatomical contact with fundus ventriculi and corpus ventriculi.…”

“…According to Stamatova-Yovcheva (2016), in rabbits, the liver is found in the cranial abdominal region between the two costal arches.…”

“…Caudally, the rabbit's liver touches parts of the stomach, as lobus hepatis sinister lateralis has anatomical contact with pars cardiaca and fundus ventriculi. Lobus hepatis sinsister medialis borders corpus ventriculi and lobus hepatis dexter is adjacent to pars pylorica (Stamatova-Yovcheva, 2016). Detailed information about the structure of the liver of the domestic rabbit by using helical CT for a transversal scan of the head, abdomen and 8th thoracic vertebra (Th8) was provided (Stamatova-Yovcheva, 2016).…”

In the transverse CT helical anatomical study in the segment of the 13th thoracic vertebra (Th13), with a stomach partially filled with food content, the anatomical adjacencies of the liver with the parts of the stomach, pancreas, segments of the caecum and the ascending colon were established (Stamatova-Yovcheva, 2016).…”
