The wall of the left atrium was thicker and more uniform than that of the right atrium. However, the lumen of the right atrium was more voluminous than that of the left atrium. The average thickness of the pectinate muscles was 0.9 mm on the left atrium while 0.7 mm on the right atrium. The pectinate muscles were connected by the muscle bridges on the left atrium, but not on the right. The depressions on the right atrium wall were well defined and polygonal in shape; however, depressions on the left atrium were not as prominent.eninfo:eu-repo/semantics/closedAccessanatomyatriumavianpectinate musclesscanning electron microscopeArticle15542172202-s2.0-2642583963N/AWOS:000222007500006Q4
