absracta rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. the superior root of the ansa cervicalis was formed by the c1 ventralramus. it accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. moreover the c1 ventral ramus formed fromthe sheath and joined the inferior root from c2 and c3 ventr...

case presentation a 30-year-old male patient with a history of severe, throbbing, constant pain in the lower mandibular molars was referred to the department of endodontics of hamedan dental university. the patient’s medical history was noncontributory. the buccal object rule (same-lingual opposite-buccal technique) confirmed the additional root as a distolingual root (radix entomolaris). follo...

acquaintance with the different anatomical variations of the arterial supply of the gallbladder is of great importance in hepatobiliary surgical procedures. a rare variation of the hepatobiliary arterial system was found during anatomical dissection of a female iranian cadaver. two cystic arteries were present, the first arising directly from the right hepatic artery and the second from the gas...

Abstract. Natural populations of Carpinus orientalis Mill. Shrub lands occur mainly in high and middle altitudes of the Hyrcanian forests, N. Iran, particularly on steep rocks and forest outcrops. There are some discrepancies on the intra-specific delimitation of this important woody species. The aim of the current study was to examine the anatomical variation of stems and leaves of sixteen pop...

The sciatic nerve is a largest single nerve of the lumbosacral nervous plexus. This nerve innervates all muscles of the leg and foot as well as the flexor muscles of the knee joint. Many variations in the direction and relations of sciatic nerve were described. The current case report presented a thick septum situated posterior to the sciatic nerve and its branches spread throughout the back of...
