Anatomical studies on the cystic artery of sheep (Ovis aries)

B Venkatesh, G Purushotham, D Pramod Kumar and KBP Raghavender
Cystic artery in the present study was the branch of right hepatic artery it gave small branches to the duct and lateral part of the right lobe and quadrate lobe. The observed mean external diameter of cast preparations was 0.96 ± 0.05 mm. Similarly, morbid arteriography revealed 0.87 ± 0.05 mm. The endothelium was lined by a single layer of flat squamous type cells. The nucleus shape was oblong and resembled tear drop. The subendothelial layer was very thin. The internal elastic membrane was continuous. The tunica media constituted the bulk of the arterial wall and chiefly consisted of 10 to 15 smooth muscle cells. The external elastic lamina was indistinct. There was a no evidence of vaso vasorum and nervi vasorum. The tunica intima, media, adventitia and total wall thickness was 4.48 ± 0.63, 16.64 ± 1.9, 10.88 ± 1.18 and 32.03 ± 2.75 respectively while the long and short luminal diameters were 75.52 ± 2.56 and 12.8 ±1.9 respectively. The endothelium, basement membrane and externa of cystic artery exhibited intense alcian blue activity which indicated the presence acid mucopolysaccharides while weak alcian blue activity was observed in media and strong PAS reaction was noticed in tunica externa. The frozen sections revealed intense AKP activity in endothelium and tunica externa while moderate and scattered in tunica media. The ACP activity was very weak in endothelium and media while moderate in tunica externa.
