ABSTRACT
A study on frequencies of various types of the hypoglossal canal was done on 187 Thai skulls, 123 males and 64 females. Type 1 was the most predominant type, found on either right or left side. Type 2, 3 and 4 appeared less respectively. Type 5 was the lest common type, found in only one skull and on only one side. The comparison with European, Egyptian and American Indian skulls showed the difference in frequencies with statistically significance.
ABSTRACT
A study on the incidence of the lateral costal artery was performed upon 117 Thai cadavers; 69 males and 48 females. The artery was found in 14 cases (11.97%), 11 males and 3 females. Bilateral arteries were observed in 5 cadavers. In 5 cadavers the artery occurred on the right side, and in 4 cases it was seen on the left. Most of the arteries terminated in the second, the third and the fourth intercostal spaces. Only in the case of an 84-year-old male with the bilateral arteries had the right artery end in the seventh intercostals space while the left artery reached to the fifth. All lateral costal arteries rose from the internal thoracic region.
ABSTRACT
After the medical curriculum of the Faculty of Medicine, Siriraj Hospital, was changed, the premedical period was reduced from two years to one year. Academic credit was also decreased from 73 to 50 credits. Basic knowledge in Biology of medical students who studied under the new curriculum was less than the students who studied the old one. Evaluation of the Students’ Anatomical knowledge revealed that there was no significant difference among three groups of medical students. This indicated that the reduction of curriculum did not effect academic performance of medical students.
